Introduction

Welcome to the Veriff documentation. This documentation will help you get started with Veriff. If you have any questions you can use Intercom on the bottom of the page or support@veriff.com to get in contact with us.

Getting started with Veriff

Signing up

Fill-in the form at veriff.com and an e-mail with instructions on how to log in will be sent to you.

Logging in

Veriff’s environment can be accessed by going to Veriff Station. To log in for the first time, please use the link sent in the email and follow instructions.

New users for your colleagues can be created by an Administrator role account in Veriff Station Team page.

How to find your API keys

Your API keys are stored in the Veriff Station. Choose Integrations in the top menu, then integration you need.

Once you open integration you'll see Publishable key and Private key. Private key is your API secret and Publishable key is the API Key

There are two types of Integrations that can be created by Station user:

• Test Integrations are used for development and sessions will not count towards paid usage. Veriff will not provide decisions on sessions created for test integrations

• Live Integrations are used for production and sessions created will count towards paid usage and Veriff will be providing decisions for those

Sessions Lifecycle

Generating verification with Veriff

Generating sessions manually

To generate a verification:

• Click "Verifications" on top menu
• Click "Add Verification" from the opened window
• Choose "Integration"
• Fill in the first name, last name
• Click "Generate Verification"
• Click on "Share" to copy the URL or QR image into clipboard

Generating sessions in code

{
    "verification": {
        "callback": "https://veriff.com",
        "person": {
            "firstName": "John",
            "lastName": "Smith"
        },
        "document": {
            "type": "PASSPORT",
            "country": "EE"
        },
        "vendorData": "unique id of a user",
        "timestamp": "2016-05-19T08:30:25.597Z"
    }
}

The simplest way to get a verification link for web verification flow is to create JSON object containing the user's name and the redirect(callback) URL to which the user will be sent after completing web verification flow (usually it is "Thank you" or "Waiting" page on your side). Then use HTTP POST to send the object to https://stationapi.veriff.com/v1/sessions, with Content-Type application/json and the X-AUTH-CLIENT header containing your API Key.

In response, a JSON session ID and a URL will be sent as follows:

{
    "status": "success",
    "verification":{
        "id":"f04bdb47-d3be-4b28-b028-............",
        "url": "https://alchemy.veriff.com/v/sample-url.................",
        "sessionToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJh............",
        "baseUrl": "https://alchemy.veriff.com"
    }
}

The URL of the verification session is where end-user should be redirected on web.

The session ID should be saved on your end - you can tie back the webhook responses to your customer record that way.

The session token is a JSON web token that consists of HS256 encrypted session ID and session creation timestamp. It will expire in 7 days.

Once the end user completes the verification flow, they will be redirected to the callback URL. If callback URL is not specified for the session, user will be redirected to Integration's default Callback URL, which can be set up in Station. It is important to note, the callback does not contain any decision or verification information yet.

Receiving decisions

There are 3 options to fetch decisions for a verification session:

• Manual: Station Verifications list displays sessions' details including decisions made

• Webhooks

• /sessions/{sessionId}/decision endpoint

Signing requests with the X-HMAC-SIGNATURE

The X-HMAC-SIGNATURE guarantees to us, that API calls are initiated by you. It is based on the shared key (API private key) that is known only by you and Veriff.

X-HMAC-SIGNATURE is a special header which value is a signature generated using HMAC method.

To generate the value you need to generate a keyed hash value using your API private key with the HMAC-SHA256 function.

Integrations

Android SDK integration

Android SDK Requirements

Veriff Android SDK requires Android 5.0 or newer at runtime. The project must also have Java 8 enabled and use AndroidX instead of support library.

Adding Android SDK

Open the root build.gradle file and add a new maven destination to the repositories in the allprojects section.

allprojects {
    repositories {
        maven { url "https://cdn.veriff.me/android/" } //veriff
        google()
        jcenter()
    }
}

Add the Veriff SDK dependency to the application build.gradle file:

implementation 'com.veriff:veriff-library:3.+'

Permissions

The SDK will request all the permissions it needs, please make sure that the CAMERA, RECORD_AUDIO permissions are not explicitly removed using tools:node="remove" in your app`s manifest file. Ignore this if you are not explicitly removing any permissions.

Starting the verification flow

The verification flow must be launched from the vendor Activity class with a unique session. A session is valid for 7 days and expires automatically after that.

import com.veriff.VeriffSdk;

Intent intent = VeriffSdk.createLaunchIntent(activity, sessionUrl);
startActivityForResult(intent, REQUEST_CODE);

Parameters are defined as below

Parameters	Description
sessionUrl	sessionUrl should be unique for each call. Check /sessions endpoint in the API documentation here to learn how to generate one.
REQUEST_CODE	Define an integer constant REQUEST_CODE in your activity which can be used to compare in onActivityResult

Customizing the SDK

Setting a theme (Optional)

Starting from version 2.6.0 you can customize the look and feel of the SDK flow by passing a VeriffBranding instance via VeriffConfiguration to createLaunchIntent. See the example below.

VeriffBranding branding = new VeriffBranding.Builder()
        .themeColor(getResources().getColor(R.color.theme_color))
        .backgroundColor(getResources().getColor(R.color.background_color))
        .statusBarColor(getResources().getColor(R.color.status_bar_color))
        .primaryTextColor(getResources().getColor(R.color.primary_text_color))
        .secondaryTextColor(getResources().getColor(R.color.secondary_text_color))
        .toolbarIcon(R.drawable.toolbar_icon)
        .bulletPoint(R.drawable.bullet_point)
        .buttonCornerRadius(48f)
        .notificationIcon(R.drawable.notification_icon)
        .build();

VeriffConfiguration configuration = new VeriffConfiguration.Builder()
        .branding(branding)
        .build();


Intent intent = VeriffSdk.createLaunchIntent(activity, sessionUrl, configuration);
startActivityForResult(intent, REQUEST_CODE);

All custom values for branding are optional. If a value is not provided for them the default Veriff color or icon will be used.

Custom intro screen

Veriff supports replacing introduction screen with a custom client developed introduction screen for eligible clients. First, please ask about this possibility from your account manager. In case we can offer it for you then removal process is following:

• You agree your own introduction screen visuals and copy with our account manager and get relevant legal documents signed in case they are needed.
• After that Veriff will enable custom introduction screen from backend for your integrations.
• After you have implemented your own introduction screen you can change the configuration option specified below.

VeriffConfiguration configuration = new VeriffConfiguration.Builder()
        .customIntroScreen(true)
        .build();

Note: This step alone is not enough to enable the custom intro screen. Make sure to contact your account manager so they can enable the feature for your integration.

Setting a locale for the SDK (Optional)

Starting from version 3.1.0 you can set a locale(java.util.Locale) for the SDK from the app itself. Even if you set a locale for the SDK the users will still be able to change the language during the flow if they wish to.

Locale appLocale = Locale.ENGLISH;
VeriffConfiguration configuration = new VeriffConfiguration.Builder()
        .locale(appLocale)
        .build();

Intent intent = VeriffSdk.createLaunchIntent(activity, sessionUrl, configuration);
startActivityForResult(intent, REQUEST_CODE);        

Getting the verification status

Veriff SDK sends callbacks to your mobile application. To capture the result override the onActivityResult method in your activity that started the verification flow:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE) {
        VeriffResult result = VeriffResult.fromResultIntent(data);
        if (result != null) {
            handleResult(result); //see below for handling the result
        }
    }
    super.onActivityResult(requestCode, resultCode, data);
}

public void handleResult(VeriffResult result) {
    switch (result.getStatus()) {
    case DONE:
        // Session is completed from user's perspective
        break;
    case CANCELED:
        // User cancelled the session
        break;
    case ERROR:
        // An error occurred during the flow, Veriff has already shown UI, no need to display
        // a separate error message here
        Log.w(TAG, "Verification error occurred: " + result.getError());
        break;
    }
}

Note: After the verification data is uploaded, the SDK does not wait for the final verification result. The SDK only notifies whether the verification data upload was successful or not. The verification result is sent to the vendor`s server asynchronously in the background. (Reference for that can be found here).

Adding error logging

To turn on logging, simply add your logging implementation instance (instance of VeriffLogger class) to the SDK before launching the SDK as shown.

VeriffSdk.setLogger(<Instance of your logging class>);
Intent intent = VeriffSdk.createLaunchIntent(activity, sessionUrl);
startActivityForResult(intent, REQUEST_CODE);

Excluding ML Kit support

Veriff Android SDK uses ML Kit for things like face detection, barcode scanning or text recognition to improve the end-user flow experience. It uses on-device models that are predownloaded with play services. If your app cannot use play services at all then you can exclude the transitive mlkit dependency - this will remove any dependencies on ML Kit and disable the use of these ML modules at runtime:

implementation('com.veriff:veriff-library:3.15.0') {
    exclude group: 'com.veriff', module: 'mlkit'
}

Migrating to Veriff Android SDK 3.0.0

Follow these steps to migrate from SDK 2.x.y to 3.0.0

Switch to AndroidX

Veriff SDK 3.0.0 requires AndroidX 1.0.0 or later. If you haven't switched to AndroidX in your app yet then follow this guide.

Enable Java 8

Veriff SDK 3.0.0 requires Java 8 language features to be enabled in your project. If you don't have this enabled already then add this to your app/build.gradle file under the android {} section:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

See more here.

Switch from baseUrl and sessionToken to sessionUrl

The new 3.0.0 SDK requires a single sessionUrl parameter instead of baseUrl and sessionToken. See the documentation here. As a backwards compatibility measure, if a sessionToken value is passed into the sessionUrl parameter then it will still work with an assumed baseUrl of magic.veriff.com.

Use com.veriff.* classes instead of mobi.lab.veriff.data.* ones

The name and location of the main SDK entry class has changed from mobi.lab.veriff.data.Veriff to com.veriff.VeriffSdk. The API is largely similar - instead of Veriff.Builder there's a VeriffSdk.createLaunchIntent method that returns an Intent which you can then use to launch veriff. See example here.

If you are using Branding to customize the look and feel of the SDK then it has a new name - VeriffBranding. The builder interface has been streamlined by removing the set* prefixes from all the methods. Read more about customization here.

Use com.veriff.VeriffResult instead of reading return Intent directly

Starting with 3.0.0 there's a new way to handle the result of the verification flow. Instead of reading INTENT_EXTRA_STATUS directly from the returned data intent, use VeriffResult.fromResultIntent(data) to get a result object with a status field and an optional error field. We've reduced status to just three - CANCELED, ERROR, DONE. In case of ERROR the error field contains more information. See the example here.

Remove usage of deprecated types

While the old SDK entrypoints are still present for backwards compatibility they will be removed in the future. Please remove usage of any SDK type marked with @Deprecated - the easiest way to discover these is to look at your Gradle build log with Java/Kotlin compilation warnings turned on.

Here's a list of old deprecated classes due to be removed in a future release:

mobi.lab.veriff.data.Veriff
mobi.lab.veriff.data.Veriff.Builder
mobi.lab.veriff.data.VeriffConstants
mobi.lab.veriff.data.Branding
mobi.lab.veriff.data.Branding.Builder
mobi.lab.veriff.data.DrawableProvider
mobi.lab.veriff.util.LogAccess
mobi.lab.veriff.util.LogAccess.LogLevel
mobi.lab.veriff.util.LogcatLogAccess
mobi.lab.veriff.service.VeriffStatusUpdatesService

Android SDK Changelog

Please refer to release notes.

iOS SDK integration

iOS SDK Requirements

Integration Veriff iOS SDK requires at least iOS version 9.0

Adding the SDK to the project

VeriffSDK requires the latest stable version of Xcode available at the time the release is made. If you would like to use versions that are independent of Swift versions, please integrate .xcframework.

Using Swift Package Manager

To integrate Veriff SDK with Swift Package Manager, open File > Swift Packages > Add Package Dependency and add the Veriff iOS SDK Swift Package repository url as stated below;

https://github.com/Veriff/veriff-ios-spm/

After clicking Next, select the version you would like to integrate and complete the integration.

Using Cocoapods

To integrate Veriff SDK with Cocoapods, please add the line below to your Podfile and run pod install. New to Cocoapods? Learn more here.

pod 'VeriffSDK'

After installation is done, use the newly created .xcworkspace file of your project.

Using Carthage

To integrate VeriffSDK into your Xcode project using Carthage, specify the required libraries below in your Cartfile.

binary "https://cdn.veriff.me/ios/carthage/VeriffSDK.json"

After a carthage update add Veriff framework from Carthage/Build/<platform> to project. To target build phases carthage copy-frameworks run script step add the following input files:

$(SRCROOT)/Carthage/Build/iOS/Veriff.framework

To target build phases carthage copy-frameworks run script step add the following output files:

$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/Veriff.framework

Using XCFramework

To integrate VeriffSDK into your project manually, please download VeriffSDK.

After framework is downloaded, drag VeriffSDK.xcframework into the Frameworks, Libraries, and Embedded Content section of your target and that's all!

Adding permissions

Add usage descriptions to application Info.plist

Not adding these usage descriptions causes system to kill application when it requests the permissions when needed.

Veriff iOS SDK requires camera, microphone, photo library and NFC reader permissions for capturing photos, video and scanning passport during identification. Your application is responsible to describe the reason why camera, microphone, photo library and NFC reader is used. You must add 4 descriptions listed below to info.plist of your application with the explanation of the usage.

• NSCameraUsageDescription
• NSMicrophoneUsageDescription
• NSPhotoLibraryUsageDescription
• NFCReaderUsageDescription

Add required steps for NFC scanning

The application needs to define the list of application IDs or AIDs it can connect to, in the Info.plist file. The AID is a way of uniquely identifying an application on a ISO 7816 tag, which is usually defined by a standard. Passports use the AID A0000002471001.

<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
<array>
  <string>A0000002471001</string>
</array>

Add a new entitlement for NFC scanning, available since iOS 13. This new entitlement is added automatically by Xcode when enabling the Near Field Communication Tag Reading capability in the target Signing & Capabilities. After enabling the capability the *.entitelments file needs to contain the TAG format:

<key>com.apple.developer.nfc.readersession.formats</key>
<array>
    <string>NDEF</string>
    <string>TAG</string>
</array>

Starting verification flow

Import Veriff in your code

// Swift
import Veriff

// Objective-C
@import Veriff;

In order to use Veriff SDK, please import it to your class that will use the SDK.

Start the verification flow

In order to start the verification flow please call the method below with the sessionUrl you receive from your backend implementation [Required].

// Swift
let veriff = VeriffSdk.shared
veriff.startAuthentication(sessionUrl: sessionUrl)

// Objective-C
VeriffSdk *veriff = [VeriffSdk shared];
[veriff startAuthenticationWithSessionUrl:sessionUrl];

Parameters are defined as below;

Parameters	Description
sessionUrl	sessionUrl should be unique for each call. Check /sessions endpoint in the API documentation here to learn how to generate one.
configuration	Optional VeriffConfiguration object. Refer to Customize user interface (Optional) for how to use it.

Customize user interface (Optional)

Setting theme color, font and logo

You can customize the Veriff user interface through your own application, by letting the SDK know of your brand's main color, font and logo. The Branding class allows customization of the theme color, navigation bar title image, button height and corner radius, background color, status bar color, primary and secondary text colors, bullet point image, button title text casing and font. In order to use customization set the branding property of VeriffConfiguration before you start the verification.

See the Veriff SDK customization guide document to see what it looks like.

// Swift
let yourColor = UIColor.someColor()
let yourImage = UIImage(named: "logo.png")
let branding = VeriffSdk.Branding(themeColor: yourColor, logo: yourImage)
branding.buttonHeight = CGFloat.buttonHeight
branding.buttonCornerRadius = CGFloat.cornerRadius
branding.backgroundColor = UIColor.backgroundColor
branding.statusBarColor = UIColor.statusBarColor
branding.primaryTextColor = UIColor.primaryTextColor
branding.secondaryTextColor = UIColor.secondaryTextColor
branding.bulletPoint = UIImage(named: "bulletPoint.png")
branding.isTextUppercase = false
branding.font = VeriffSdk.Branding.Font(regularFontName: "Font", lightFontName: "Font-Light", semiBoldFontName: "Font-SemiBold", boldFontName: "Font-Bold")

// Objective-C
UIImage *logo = [UIImage imageNamed:@"logo.png"];
VeriffBranding *branding = [[VeriffBranding alloc] initWithThemeColor:[UIColor greenColor] logo:logo];
branding.buttonHeight = 56;
branding.buttonCornerRadius = 5;
branding.backgroundColor = [UIColor lightGrayColor];
branding.statusBarColor = [UIColor redColor];
branding.primaryTextColor = [UIColor darkTextColor];
branding.secondaryTextColor = [UIColor lightTextColor];
branding.bulletPoint = [UIImage imageNamed:@"bulletPoint.png"];
branding.isTextUppercase = false;
branding.font = [[VeriffBrandingFont alloc] initWithRegularFontName: @"Font" lightFontName: @"Font-Light" semiBoldFontName: @"Font-SemiBold" boldFontName: @"Font-Bold"];

Setting the user interface language

The Veriff iOS SDK allows setting the language of the SDK. In order to use this language, please set the languageLocale property of VeriffSdk.Configuration before you start the verification.

// Swift
let locale = Locale(identifier: "et")

// Objective-C
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"et"];

Create the configuration object

// Swift
let configuration = VeriffSdk.Configuration(branding: branding, languageLocale: locale)

// Objective-C
VeriffConfiguration *configuration = [[VeriffConfiguration alloc] initWithBranding:branding languageLocale:locale];

Custom intro screen

Veriff supports replacing introduction screen with a custom client developed introduction screen for eligible clients. First, please ask about this possibility from your account manager. In case we can offer it for you then removal process is following:

• You agree your own introduction screen visuals and copy with our account manager and get relevant legal documents signed in case their needed.
• After that Veriff will enable custom introduction screen from backend for your integrations.
• After you have implemented your own introduction screen you can change the configuration option specified below.

configuration.customIntroScreen = true

Note: This step alone is not enough to enable the custom intro screen. Make sure to contact your account manager so they can enable the feature for your integration.

Start the verification flow by using the configuration

// Swift
let veriff = VeriffSdk.shared
veriff.startAuthentication(sessionUrl: sessionUrl, configuration: configuration)

// Objective-C
VeriffSdk *veriff = [VeriffSdk shared];
[veriff startAuthenticationWithSessionUrl:sessionUrl configuration:configuration];

Handling result codes from SDK

To receive session results, you must implement the VeriffSdkDelegate protocol and assign a delegate to the VeriffSdk instance.

veriff.delegate = self

The Veriff SDK returns a number of result codes that your application can handle.

// Swift
extension VerificationService: VeriffSdkDelegate {
    func sessionDidEndWithResult(_ result: Veriff.Result) {
        switch result.status {
        case .done:
            // The user successfully submitted the session
            break
        case .canceled:
            // The user canceled the verification process.
            break
        case .error(let error):
            switch error {
                // ...
            }
        }
    }
}

// Objective-C
- (void)sessionDidEndWithResult:(VeriffResult *)result {
    switch (result.status) {
    case VeriffStatusDone:
        // The user successfully submitted the session
        break;
    case VeriffStatusCanceled:
        // The user canceled the verification process.
        break;
    case VeriffStatusError:
        if (result.error == nil) { break; }
        switch (result.error.code) {
            // ...
        }
    }
}

You can find the description of status codes below:

• done The session status is finished from clients perspective
• canceled User canceled the verification process
• error An error occurred. To see the error reason:
  • In Swift: check the associated value (Veriff.Error) passed by error status.
  • In Objective-C: check result.error.code (VeriffErrorCode).

Notes

• The Veriff SDK always shows an error screen itself. The errors returned by the session are to inform your application.
• After the verification data is uploaded, the SDK does not wait for the final verification result. The SDK only notifies whether the verification data upload was successful or not. The verification result is sent to the vendor`s server asynchronously in the background. (Reference for that can be found here).

Migrating to Veriff iOS 3.0.0

Switch from baseUrl and sessionToken to sessionUrl

The Veriff object in the SDK 3.0.0 takes a required sessionUrl and an optional VeriffConfiguration instance as parameters into initialisation. The sessionUrl is received from your backend implementation (see the documentation here), it is composed of the baseUrl and sessionToken sent to the VeriffConfiguration object in earlier versions.

Updated VeriffConfiguration object

The VeriffConfiguration struct now takes in branding and languageLocale as initialisation parameters.

The new VeriffDelegate method

You can now receive session results via func sessionDidEndWithResult(_ result: Veriff.Result) instead of the obsolete func onSession(result: VeriffResult, sessionToken: String). The sessionToken is included in the Veriff.Result as an instance variable.

Use Veriff.Result instead of VeriffResult

The new Veriff.Result struct comprises status: Status and sessionToken: String? instance variables. The Status enum can be of three types: done, canceled, error. The description variable on the Veriff.Result returns additional information as a string. See the example here.

Migrating to Veriff iOS 4.0.0

Rename Veriff instances to VeriffSdk

The name Veriff was used both for our module and public class name. However this blocked us from supporting Swift Package Manager due to Swift compiler bug. We renamed our public class name to VeriffSdk.

VeriffConfiguration is now VeriffSdk.Configuration

VeriffConfiguration struct is moved under VeriffSdk. Please replace the occurrences of VeriffConfiguration with VeriffSdk.Configuration.

Branding is now VeriffSdk.Branding

Branding struct is moved under VeriffSdk. Please replace the occurrences of Branding with VeriffSdk.Branding.

Rename VeriffDelegate to VeriffSdkDelegate

Please replace the occurrences of VeriffDelegate with VeriffSdkDelegate.

VeriffSdk.Result.description made non-optional

If you were dealing with unwrapping it, feel free to remove it.

VeriffSdk.Result.sessionToken removed and VeriffSdk.Result.sessionUrl added instead

Please remove the occurrences of sessionToken. You can now use sessionUrl to get the full sessionUrl including token.

Launching the verification flow

Import plugin in your code

In order to use Veriff plugin, please import it to your class that will use it. import 'package:veriff_flutter/veriff_flutter.dart'

Start verification flow

In order to start the verification flow please create a configuration with sessionUrl you receive from your backend implementation[Required].

Configuration config = Configuration(sessionUrl);

Then pass the configuration to Veriff object and start the verification flow;

Veriff veriff = Veriff();

try {
      Result result = await veriff.start(config);
      print(result.status);
      print(result.error);
    } on PlatformException {
      // handle exception
    }

Customize user interface (Optional)

You can customize Veriff SDK user interface in your application by defining your brand main color and logo.

See the Veriff SDK customization guide document to see what it looks like.

Veriff Flutter plugin allows the customization of UI elements and icons in the SDK flow by passing the optional parameters when launching Veriff;

AssetImage logo = AssetImage(path_of_image);
Branding branding = Branding(
        themeColor: "#ff00ff",
        backgroundColor: "#f2ff00",
        statusBarColor: "#ff7700",
        primaryTextColor: "#52b35c",
        secondaryTextColor: "#3a593d",
        buttonCornerRadius: 5,
        logo: logo,
        androidNotificationIcon: "ic_notification",
      );

Note: If you are customizing androidNotificationIcon don't forget to add the icon to the android/res/drawable folder.

And pass the branding object with configuration for starting the verification flow;

Configuration config = Configuration(sessionUrl, branding: branding);

When a color isn't defined, the default Veriff theme color is used. Same applies to image assets - when they aren't defined, the defaults are used.

Setting the user interface language

Veriff Flutter plugin supports setting the language of the UI. In order to use this feature, please pass the locale identifier as in example below;

Configuration config = Configuration(sessionUrl, branding: branding, languageLocale: "et");

Custom intro screen

Veriff supports replacing introduction screen with a custom client developed introduction screen for eligible clients. First, please ask about this possibility from your account manager. In case we can offer it for you then removal process is following:

• You agree your own introduction screen visuals and copy with our account manager and get relevant legal documents signed in case their needed.
• After that Veriff will enable custom introduction screen from backend for your integrations.
• After you have implemented your own introduction screen you can change the configuration option specified below.

config.useCustomIntroScreen = true;

Handling the results from plugin

The Result returned by start method will have a status that is one of Status.done, Status.canceled and Status.error. In case Status.error is received, you will also have an error description that is one of the list below;

• Error.cameraUnavailable
• Error.microphoneUnavailable
• Error.networkError
• Error.sessionError
• Error.deprecatedSDKVersion
• Error.unknown
• Error.nfcError
• Error.setupError
• Error.none

You can check the statuses and errors using switch-case as in example below;

switch (result.status) {
        case Status.done:
          print("Session is completed.");
          break;
        case Status.canceled:
          print("Session is canceled by the user.");
          break;
        case Status.error:
          switch (result.error) {
            case Error.cameraUnavailable:
              print("User did not give permission for the camera");
              break;
            case Error.microphoneUnavailable:
              print("User did not give permission for the microphone.");
              break;
            case Error.networkError:
              print("Network error occurred.");
              break;
            case Error.sessionError:
              print("A local error happened before submitting the session.");
              break;
            case Error.deprecatedSDKVersion:
              print(
                  "Version of Veriff SDK used in plugin has been deprecated. Please update to the latest version.");
              break;
            case Error.unknown:
              print("Uknown error occurred.");
              break;
            case Error.nfcError:
              print("Error with NFC");
              break;
            case Error.setupError:
              print("Error with setup");
              break;
            case Error.none:
              print("No error.");
              break;
            default:
              break;
          }
          break;
        default:
          break;
}

React Native SDK integration

React Native SDK requirements

Integration with Veriff React Native SDK requires the project to target at least iOS version 9.0 and Android version 5.0 (api 21) or higher.

Note: If you have created your react native app using expo, you will have to eject out of expo at this point(if you have not ejected out already) since expo does not support native modules Check the Caveats section here for more info on that.

Add the SDK to a project

Add the Veriff React Native SDK to your package.json file:

npx yarn add @veriff/react-native-sdk

Or if using npm:

npm install @veriff/react-native-sdk --save

Update Android build.gradle file

Open the root build.gradle file in the android folder and add a new maven destination to the repositories in the allprojects section. The best place is right after the local node_modules repositories and before the google() repository.

allprojects {
    repositories {
        // ... local react native repos
        maven { url "https://cdn.veriff.me/android/" } //veriff
        google()
        jcenter()
    }
}

iOS Specific setup

Add Swift to the ios module

Veriff SDK requires your ios module to have some Swift code. If you don't have any Swift code yet then add a new empty.swift file in Xcode. If Xcode offers to add a bridging header then add it.

Update iOS Podfile

Open Podfile in the ios folder and make sure that platform is 9.0 or higher:

platform :ios, '9.0'

Also make sure your main target in the Podfile contains use_native_modules! directive at the end:

target 'MyApp' do
  # pod 'foo'...

  use_native_modules!
end

Add usage descriptions to application Info.plist

Not adding these usage descriptions causes system to kill application when it requests the permissions when needed.

Veriff requires camera, microphone and NFC reader permissions for capturing photos, video and scanning passport during identification. Your application is responsible to describe the reason why camera, microphone and NFC reader is used. You must add 3 descriptions listed below to Info.plist of your application with the explanation of the usage.

• NSCameraUsageDescription
• NSMicrophoneUsageDescription
• NFCReaderUsageDescription

Add required steps for NFC scanning

The application needs to define the list of application IDs or AIDs it can connect to, in the Info.plist file. The AID is a way of uniquely identifying an application on a ISO 7816 tag, which is usually defined by a standard. Passports use the AID A0000002471001.

<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
<array>
  <string>A0000002471001</string>
</array>

Add a new entitlement for NFC scanning, available since iOS 13. This new entitlement is added automatically by Xcode when enabling the Near Field Communication Tag Reading capability in the target Signing & Capabilities. After enabling the capability the *.entitelments file needs to contain the TAG format:

<key>com.apple.developer.nfc.readersession.formats</key>
<array>
    <string>NDEF</string>
    <string>TAG</string>
</array>

Set the iOS target in Xcode

Make sure that the 'iOS Deployment Target' in Xcode (under Project > target > Info > Deployment Target) is set to iOS 9.0 or later.

Using the Veriff React Native SDK

Starting the verification flow

In order to use Veriff SDK, please import it to the file that will use the SDK.

import VeriffSdk from '@veriff/react-native-sdk';

Before you can launch the verification flow you'll need a session URL. See our documentation on generating one. Once you have the URL you can launch Veriff using VeriffSdk imported earlier:

var result = await VeriffSdk.launchVeriff({ sessionUrl: SESSION_URL });

User Interface customization

You can customize Veriff SDK user interface in your application by defining your brand main color and logo.

See Veriff SDK customization guide document on how it looks.

Veriff React Native SDK allows the customization of various colors and images in the SDK flow by passing in these optional properties when launching Veriff:

var result = await VeriffSdk.launchVeriff({
    sessionUrl: SESSION_URL,
    branding: {
      themeColor: '#ff00ff',
      backgroundColor: '#ffffff',
      statusBarColor: '#ff00ff',
      primaryTextColor: '#000000',
      secondaryTextColor: '#333333',
      buttonCornerRadius: 28,
      logo: 'parrot', // see alternative options for logo below
      androidNotificationIcon: 'ic_parrot'
    },
  });

When a color isn't defined the default Veriff theme color is used. Same applies to image assets - when they aren't defined the defaults are used. The image assets need to be added into Xcode assets in the iOS project and into drawable folders in the Android project. In the example above you would need to add an image asset named 'parrot' into Xcode assets and both 'parrot.png' and 'ic_parrot.png' to Android drawable folders in android/src/main/res.

Alternative ways to provide the logo

Instead of using platform-specific image assets you can provide a URI to an image which will then be used:

var result = await VeriffSdk.launchVeriff({
    sessionUrl: SESSION_URL,
    branding: {
      themeColor: '#ff00ff',
      logo: { uri: 'http://example.com/logo/parrot.jpg' },
    },
  });

React Native assets are also supported through resolveAssetSource:

const resolveAssetSource = require('react-native/Libraries/Image/resolveAssetSource');
const parrot = require('./img/parrot.png');

var result = await VeriffSdk.launchVeriff({
    sessionUrl: SESSION_URL,
    branding: {
      themeColor: '#ff00ff',
      logo: resolveAssetSource(parrot),
    },
  });

Setting the user interface language

The Veriff RN SDK allows setting the language of the SDK. In order to use this language, please pass the locale as in example below;

var result = await VeriffSdk.launchVeriff({
    sessionUrl: SESSION_URL,
    branding: {
      themeColor: '...',
    },
    locale: 'et'
  });

Handling the result from the SDK

The result returned by launchVeriff will have a status field that is one of either VeriffSdk.statusDone, VeriffSdk.statusCanceled or VeriffSdk.statusError. In case of statusError there will be a error code (not human-readable) in the error field.

var result = await VeriffSdk.launchVeriff({ sessionUrl: SESSION_URL });
switch (result.status) {
  case VeriffSdk.statusDone:
    // user submitted the images and completed the flow
    // note that this does not mean a final decision yet
    break;
  case VeriffSdk.statusCanceled:
    // user canceled the flow before completing
    break;
  case VeriffSdk.statusError:
    // the flow could not be completed due to an error
    console.log("Veriff verification failed with error=" + result.error);
    break;
}

Migrating to React Native SDK 2.0.0

Follow these steps to migrate to React Native SDK 2.0.0 API

Use new parameter sessionUrl

New API uses sessionUrl instead of a sessionToken. sessionUrl is a combination of base URL and session token.

Rename parameter navigationBarImage to logo

We renamed the navigationBarImage parameter in configuration to logo.

React Native SDK Changelog

Below is a summary of changes introduced with each version of the React Native SDK

Javascript SDK Integration

Veriff JS SDK, is a simple and customisable library which helps to integrate with Veriff Online Identity solution. Use this to simply include Veriff flow. You don't need any backend on your side for this including JS SDK to your website.

Install JS SDK

Include as a script tag:

<script src='https://cdn.veriff.me/sdk/js/1.1/veriff.min.js'></script>

or install it via a package manager

  $ npm install --save @veriff/js-sdk

   // CommonJS
  const Veriff = require('@veriff/js-sdk');

  // ES6 style import
  import Veriff from '@veriff/js-sdk';

Adding JS SDK

Veriff JS SDK requires one parent element in HTML:

<div id='veriff-root'></div>

It is possible to set the width of js-sdk form through style attribute:

<div id='veriff-root' style="width:400px"></div>

In order to initialize the library, API Key, parentId and onSession callback function is required.

  const veriff = Veriff({
    apiKey: 'API_KEY',
    parentId: 'veriff-root',
    onSession: function(err, response) {
      // received the response, verification can be started now
    }
  });

  veriff.mount();

By default the following form will be rendered:

onSession function is executed after the response is received from the API, response body contains a verification object with following schema:

    {
      "status": "success",
      "verification": {
          "id": "UUID V4 Identifying the verification",
          "url": "full url to which a person should be redirected in order to proceed with verification flow",
          "host": "hostname",
          "status": "status of the verification",
          "sessionToken": "JWT encoded verification token"
      }
  }

vendorData: string - Client specific data string, max 400 characters long, will be sent back unmodified using webhooks. In case the Given name / Last name / Vendor Data or all of them are known, they can be passed to the SDK, therefore text input fields will not be rendered.

  const veriff = Veriff({
    apiKey: 'API_KEY',
    parentId: 'veriff-root',
    onSession: function(err, response) {
      // received the response, verification can be started now
    }
  });
  veriff.setParams({
    person: {
      givenName: 'Foo',
      lastName: 'Bar'
    },
    vendorData: 'example@mail.com'
  });
  veriff.mount({
    submitBtnText: 'Get verified'
  });

It is possible to disable fields rendering without passing any data by not including anything in corresponding value:

  const veriff = Veriff({
    apiKey: 'API_KEY',
    parentId: 'veriff-root',
    onSession: function(err, response) {
      // received the response, verification can be started now
    }
  });
  veriff.setParams({
    person: {
      givenName: ' ',
      lastName: ' '
    },
    vendorData: ' '
  });
  veriff.mount({
    submitBtnText: 'Get verified'
  });

Additionally the input placeholder and button text value can be customised.

  const veriff = Veriff({
    apiKey: 'API_KEY',
    parentId: 'veriff-root',
    onSession: function(err, response) {
      // received the response, verification can be started now
    }
  });
  veriff.mount({
    formLabel: {
      givenName: 'First name',
      lastName: 'Family name',
      vendorData: 'Email'
    },
    submitBtnText: 'Get verified',
    loadingText: 'Please wait...'
  });

InContext Javascript SDK Integration

Use this if you would like to use incontext UI.

Install InContext JS SDK

npm install @veriff/incontext-sdk

Adding InContext JS SDK

You need to have a Veriff session URL generated before initializing the SDK. Please, see our documentation to learn how to generate one.

// ES6
import { createVeriffFrame } from '@veriff/incontext-sdk';

// CommonJS
const { createVeriffFrame } = require('@veriff/incontext-sdk');

const veriffFrame = createVeriffFrame({ url: VERIFF_SESSION_URL })

This will render a modal with adapted Veriff application in iframe. createVeriffFrame() returns an object that controls the modal.

Listening for events

Pass onEvent callback function when initializing SDK

import { createVeriffFrame, MESSAGES } from '@veriff/incontext-sdk';

createVeriffFrame({
  url,
  onEvent: function(msg) {
    switch(msg) {
      case MESSAGES.CANCELED:
        //
        break;
    }
  }
})

• msg:
  • STARTED - session status changed to 'started'.
  • CANCELED - user closed the modal.
  • FINISHED - user finished verification flow.

Closing modal

  const veriffFrame = createVeriffFrame({ url: VERIFF_SESSION_URL });
  veriffFrame.close();

Using with inline script

Include a script tag:

<script src='https://cdn.veriff.me/incontext/js/v1/veriff.js'></script>

window.veriffSDK.createVeriffFrame({ url: VERIFF_SESSION_URL });

Adding Content Security Policy to JS SDK

add_header Content-Security-Policy default-src 'self' *.veriff.me;
script-src 'unsafe-inline' 'unsafe-eval' 'self' *.veriff.me *.google-analytics.com *.googletagmanager.com *.hotjar.com *.probity.io;
img-src blob: 'self' *.probity.io *.google-analytics.com;
frame-src 'self' *.hotjar.com;
connect-src 'self' *.veriff.me *.probity.io;
style-src 'self' *.veriff.me 'unsafe-inline';

API Integration

There are a few scenarios where you may not wish to use Veriff's native SDK or Veriff's web interface to verify your customers. For example:

• you wish to completely implement your own front-end
• you wish to do an offline bulk audit of previously verified customers

In those cases, you can do the whole process using our API, according to the documentation, and not show any Veriff front end to your customers, or not expect customers to be present for the verification.

Here are the steps you should do to use the API for upload.

Create a new verification session

Create a new verification session using POST request to #sessions

The goal here is to create a new object (a verification session) that contains the one verification (referred to as 'verification', nested inside the session object in the response).

If you wish to restrict the accepted document to be the one you have on file, you can also send the document type, country, and number along with the session. Document type can be one of [‘PASSPORT’, ‘ID_CARD’, ‘RESIDENCE_PERMIT’, ‘DRIVERS_LICENSE'].

Send photos

Send photos (face, document front, document back, etc) by uploading all the pictures one by one using POST request to ‘/media’

The goal here is to upload the required photos and associate them with the verification created in step 1.

Documentation: /sessions/{sessionId} /media (POST)

Submit session for review

Submit the verification session using PATCH request to ‘/sessions/:id’

Once all the photos are uploaded, you would then update (PATCH) the verification to mark it into 'submitted' status. This marks the completion of the verification. This step requires all the photos to be submitted prior to triggering this.

Documentation: /sessions/{sessionid} (PATCH)

After these three steps, you've done your part, and the verification will then be taken care of by us.

Wait for webhook response

Veriff sends you a Decision event via Webhook using POST request. You will have to implement the listener.

This hook will be sent back asynchronously, and it contains more data, including the verified identity information.

Documentation: Webhook Decision (POST)

The webhook is sent to the URL that is configurable from Veriff Station under Integrations › Webhook Decision / Events URL.

SDK Support Policy

Support Policy for Veriff SDKs

Identity verification software, practices, and regulations move fast. To keep our software user-friendly, and maintain high conversion rates for our clients, our development team needs to be faster. To delvier an increasingly smarter, better and safer product, it's important to ditch backward compatibility layers and update SDKs at least once every three months. Our SDKs are updated every two weeks, and downloading new releases will keep your verification process smooth and error-free. All releases are fully tested by our team and before being deployed, and come with the support from our team in the form of:

• SDK support for 6 months after release, including:

  • Fixing all reported bugs in the upcoming SDK release
  • Fixing critical bugs in any final version before a major release for three months
  • In case an SDK release requires major implementation efforts, then the old version will be supported for one year

• Notifications before major changes to SDK support such as:

  • Dropping support for an SDK version, where we will inform you via email one month in advance
  • The end of the one-month grace period, after which Veriff will block future use of a specified SDK version
  • When end-users engage with outdated SDKs, they will receive a prompt to upgrade the host application

SDK release versioning To help you keep track of SDK releases, Veriff uses three numbers to represent the scale of the updates. Each release is assigned either X, Y, or Z according to the following descriptions:

• Major Release (X) - These releases may require addtional development efforts, and often come with large-scale improvements to the SDK
• Minor Release (Y) - These do not come with any mandatory development efforts on your end, but may include new functionalities that require development efforts to be activated
• Bug-fix Release (Z) - These resolve issues from the previous release and do not introduce any new features or improvements

Testing Integrations

You will have 1 Test integration pre-created for you in Veriff Station. You can create more test integrations if needed. The test integration will be used by you to test the communication between Veriff's and your system and to see how the responses are handled. Verification sessions generated for test integrations are not billed and not verified by Veriff.

To check quality of Veriff responses, please select plan and subscribe to a Trial on Billing page - this will allow to create Live integrations.

Testing verification sessions checklist

• New session link is generated
• Session data is saved with your customer record
• Sessions with odd names can be started
• Sessions with vendorData - do you get them back and do you perform actions on them
• User is granted access to your platform after receiving an "Approved" decision
• User is notified about verification failure after receiving "Resubmission" or "Declined" decision
• User is prompted to try again after receiving "Resubmission" decision
• In case of resubmitted session, user is directed to same SessionURL
• In case of disrupted session (browser close, user logout, etc), user should be directed back to earlier session
• In case generated session is over 7 days old (and thus in Expired or Abandonded status)- new session is generated
• At end of verification, callback URL redirects back to the correct place in your platform

Also see our support article for getting the desired test verification result

Testing security

• A webhook with wrong API public key should not be accepted
• A webhook with mismatched X-HMAC-SIGNATURE should not be accepted
• A webhook with invalid JSON should not break or crash your server

Testing responses

Each type of response should be accepted:

• Approved (Decision endpoint)
• Declined (Decision endpoint)
• Resubmission Requested (Decision endpoint)
• Expired (Decision endpoint)
• Abandoned (Decision endpoint)

Testing process in your app

You should test the handling of best cases as well as edge cases

• approved users handled or notified as appropriate
• declined users handled as appropriate, your back office notified if necessary
• in case of resubmission request, user is invited back to try KYC again using the same session URL
• in case of Expired or Abandoned session (after 7 days), user is not offered to continue from same session, new session URL is created

Mobile testing

Test our demo app by downloading it in the app store. iOS / Android

API Upload testing

Required tools Veriff's integration demo - js-integration-demo-master.zip Node.js - (Download - https://nodejs.org/en/download/) Notepad/TextEdit (default in Windows/Mac) or Notepad++ - (Download - https://notepad-plus-plus.org/)

1. Download and install Node.js
2. Download and extract js-integration-demo-master.zip
3. Open Command (Windows) or Terminal (Mac) on your local computer.
4. Navigate to js-integration-demo-master folder cd C:\Users\User\Desktop\Veriff API).
5. Run command >npm install
6. Open app.js with your text editing app (Notepad/TextEdit) and update 'API-Public-Key' and 'API-Private-Key' to the values in your Backoffice account (Management -> Vendor). Tokens must be in single quotes. Save the file.

const API_TOKEN = process.env.API_TOKEN || 'API-Public-Key';
const API_SECRET = process.env.API_SECRET || 'API-Private-Key';
const API_URL = process.env.API_URL || 'https://api.staging.vrff.io/v1';
const WEBHOOK_PORT = process.env.WEBHOOK_PORT || 3002;
const IMAGE_DIR = process.env.IMAGE_DIR || 'documents'

Run the app.js node app.js

Now the verification session is created and it is being processed. Check your Backoffice dashboard to review the data extracted and decision made by Veriff.

Batch testing

Batch upload tests are sometimes agreed with our onboarding team and are very use case specific. Therefore below might be not applicable for most of the clients. For batch tests customers will need to prepare dataset that will be used for testing. If you have been asked for dataset please see batch test data preparetion guide.

Response

Get the session decision with sessionId = {sessionId}

Response Properties explained:

• status: String Status of the response

• verification: object Verification request decision object. Null if decision is not available yet

  • id: String UUID v4 which identifies the verification session
  • code: 9001 (one of 9001, 9102, 9103, 9104) Verification response code. Detailed meaning of the response codes:

  Code	Meaning	Description
  9001	Positive: Person was verified	The verification process is complete. Accessing the sessionURL again will show the client that nothing is to be done here.
  9102	Negative: Person has not been verified	The verification process is complete. Either it was a fraud case or some other severe reason that the person can not be verified. You should investigate the session further and read the "reason". If you decide to give the client another try you need to create a new session.
  9103	Resubmitted: Resubmission has been requested	The verification process is not completed. Something was missing from the client and she or he needs to go through the flow once more. The same sessionURL can and should be used for this purpose.
  9104	Negative: Verification has been expired	The verification process is complete. After 7 days the session gets expired. If the client started the verification process we reply - "abandoned", otherwise, if the client never comes back to the verification, the status will be "expired".

X-HMAC-SIGNATURE

Signing requests

It is important to check that the webhook responses do indeed originate from Veriff. For that we use the X-HMAC-SIGNATURE header, which value is an HMAC-SHA256 hex encoded keyed hash using your API private key.

You can secure the webhook listener in three ways:

• Have a secure SSL server for your webhook listener (Veriff will call only HTTPS URLs which are hosted by servers with a publicly verifiable certificate)
• Check the X-AUTH-CLIENT and X-HMAC-SIGNATURE headers on the received webhooks (the signature is calculated using the API private key that only you and Veriff know)
• If it is required you may restrict your webhook listener to only accept calls from the Veriff IP range (please ask your Veriff integration onboarding specialist for those details)

How to make sure the request to your endpoint originates from Veriff:

• Make sure X-AUTH-CLIENT and X-HMAC-SIGNATURE headers are present
• Compare the X-AUTH-CLIENT header to your public api key
• Generate the keyed hash using HMAC-SHA256 function and the API private key
• Hex encode the hash
• Compare the hex encoded hash with the X-HMAC-SIGNATURE header sent by Veriff

Generating X-HMAC-SIGNATURE

Here are few code examples how to sign the request.

Example verification payload:

{"verification":{"callback":"https://veriff.com","person":{"firstName":"John","lastName":"Smith"},"document":{"type":"PASSPORT","country":"EE"},"vendorData":"unique id of a user","timestamp":"2016-05-19T08:30:25.597Z"}}

The result of the generated hash should be 6af6d95822e19e9cc707aec55395d8d363ba2c7bc4625bc04ebeca0c7bf8cd67 using code examples below with the API private key abcdef12-abcd-abcd-abcd-abcdef012345.

JavaScript / ECMAScript

const signature = crypto
  .createHmac('sha256', apiPrivateKey)
  .update(Buffer.from(verificationJsonAsString, 'utf8'))
  .digest('hex')
  .toLowerCase();

console.log(signature);

Python

signature = hmac \
    .new(api_secret, msg=verificationJsonAsString, digestmod=hashlib.sha256) \
    .hexdigest() \
    .lower()

print(signature)

PHP

<?php
  $signature = strtolower(hash_hmac('sha256', $verificationJsonAsString, $apiPrivateKey));
  echo $signature;

C# / .Net

var hmacsha256 = new HMACSHA256(Encoding.UTF8.GetBytes(api_private_key));
var hash = hmacsha256.ComputeHash(Encoding.UTF8.GetBytes(verificationJsonAsString));
var signature = Convert.ToHexString(hash).ToLower();

Console.WriteLine(signature);

Using online tooling

Use your favorite HMAC-SHA256 calculator to calculate the hash. E.g. https://codebeautify.org/hmac-generator (link opens in new window)

• Select SHA256 from the algorithm dropdown
• Paste the API private key provided earlier into "Enter Key" field
• Paste the example verification payload provided earlier into "Enter the Plain or Cipher Text" field
• Click on Generate HMAC
• The result of generated hash is the same provided earlier

Signing your request with headers

To make sure you are sending correct HTTP headers, here is the list of the headers and their values to compose the correct request.

CONTENT-TYPE: application/json
X-AUTH-CLIENT: abcdef12-abcd-abcd-abcd-abcdef012345
X-HMAC-SIGNATURE: 6af6d95822e19e9cc707aec55395d8d363ba2c7bc4625bc04ebeca0c7bf8cd67

Validating X-HMAC-SIGNATURE

We sign all responses using the same logic so you can make sure that the response is sent by Veriff using the X-HMAC-SIGNRATURE header.

Here are few examples how to validate the response signature.

JavaScript / ECMAScript

function isSignatureValid({ signature, apiPrivateKey, payload }) {
  if (payload.constructor === Object) {
    payload = JSON.stringify(payload);
  }

  if (payload.constructor !== Buffer) {
    payload = new Buffer.from(payload, 'utf8');
  }

  const digest = crypto
    .createHmac('sha256', apiPrivateKey)
    .update(Buffer.from(payload, 'utf8'))
    .digest('hex')
    .toLowerCase();

  return digest === signature.toLowerCase();
}

Testing the validation functionality

The easiest way to test the validation functionality is to setup small service in your localhost and use cURL with the correct payload to test it. This way you can test your functionality independently from our Webhook or API service.

Step 1 - Setup a simple HTTP server with a simple POST endpoint

Small JavaScript / ECMAScript code example

import express from 'express';
import bodyParser from 'body-parser';
import { createHmac } from 'crypto';
import { Server } from 'http';

const app = express();

const SERVICE_PORT = 3001;
const API_SECRET = 'abcdef12-abcd-abcd-abcd-abcdef012345';

function isSignatureValid({ signature, apiPrivateKey, payload }) {
    if (payload.constructor === Object) {
        payload = JSON.stringify(payload);
    }

    if (payload.constructor !== Buffer) {
        payload = new Buffer.from(payload, 'utf8');
    }

    const digest = createHmac('sha256', apiPrivateKey)
        .update(Buffer.from(payload, 'utf8'))
        .digest('hex')
        .toLowerCase();

    return digest === signature.toLowerCase();
}

app.use(bodyParser.json());
let server = Server(app);

app.post('/verification/', (req, res) => {
    res.json({
        isSignatureValid: isSignatureValid({
            signature: req.get('x-hmac-signature'), apiPrivateKey: API_SECRET, payload: req.body
        })
    });
})

server.listen(SERVICE_PORT, () => console.log('Server is UP \n Listening port:', SERVICE_PORT));

Step 2 - Post a prepared data into HTTP server

The curl request described below will return {"isSignatureValid":true} if you use abcdef12-abcd-abcd-abcd-abcdef012345 as an API private key to validate the signature.

curl --request POST 'http://localhost:3001/verification/' -k \
--header 'accept:application/json' \
--header 'x-auth-client:abcdef12-abcd-abcd-abcd-abcdef012345' \
--header 'x-hmac-signature:6af6d95822e19e9cc707aec55395d8d363ba2c7bc4625bc04ebeca0c7bf8cd67' \
--header 'content-type:application/json' \
--data '{"verification":{"callback":"https://veriff.com","person":{"firstName":"John","lastName":"Smith"},"document":{"type":"PASSPORT","country":"EE"},"vendorData":"unique id of a user","timestamp":"2016-05-19T08:30:25.597Z"}}'

Face Match

Prerequisites

1. You should have a document-front image of the user that needs re-authentication. This image will be passed to the verification session via API as a reference to compare the newly captured “face” image to.
2. A Face-match integration should be configured. (Reach out to your contact at Veriff to set it up for you!)

Process overview

1. Generate a session using the Face-match integration tokens. Check /sessions endpoint in the API reference here.
   Note: You can use vendorData parameter to pass a unique identifier for the user who will be verified.
2. Upload the reference image (document-front). Check /sessions/{sessionId}/media POST endpoint here.
   Note: Set context parameter as document-front while using POST media endpoint.
3. Choose face capture method:
     a. Capturing images with Veriff’s SDKs
     i. Send the end user through the verification flow to capture the new face image using one of Veriff’s SDKs (iOS, Android, React Native, Flutter, inContext). You will need the session url generated at step 1 to use the SDKs.
     Note: Session will be submitted automatically once the user takes necessary images of their face.
     b. Your own face capturing method (not recommended)
     i. Upload the user's face image via the POST media endpoint. Specify context parameter as face.
     ii. Patch session status to submitted status using PATCH /sessions/{sessionId} endpoint.
   
4. Receive the results from Veriff via webhooks.

Handling decisions

verification.status	verification.code	What to do
approved	9001	Positive: Person was verified. The verification process is complete. Accessing the sessionURL again will show the client that nothing is to be done here.
declined	9102	Negative: Person has not been verified. The verification process is complete. Either it was a fraud case or some other severe reason that the person can not be verified. You should investigate the session further and read the "reason". If you decide to give the client another try you need to create a new session.
resubmission_requested	9103	Resubmitted: Resubmission has been requested. The verification process is not completed. Something was missing from the client and they need to go through the flow once more. The same sessionURL can and should be used for this purpose. And the reference image should be uploaded again (same if related to the face, different one if related to the reference image)
expired	9104	Negative: Verification has been expired. The verification process is complete. After the session creation, if the end user has not started the verification in 7 days, the session gets expired.
abandoned		Negative: Verification has been abandoned. The verification process is complete. After the session creation, if the end user has started but not completed the verification in 7 days, the session gets abandoned status.

Handling the decision reasons

verification.status	verification.reasonCode	verification.reason	What to do
declined	509	Person showing the document does not match document photo	User’s new face doesn’t match with reference uploaded image
declined	515	Attempted deceit, device screen used for face image	Face image shown from a device/screen/printout.
declined	526	Attempted deceit, photos streamed	Face images are being presented as a slide show/stream. Note: This feature comes when using Veriff's end user flow to capture the images
declined	106	Known fraud	Suspicious multi/country accesses, previously declined multiple times for fraud
declined	108	Decline - Velocity/abuse duplicated user	This feature needs to be enabled for your integration. It is not active by default
declined	109	Decline - Velocity/abuse duplicated device	This feature needs to be enabled for your integration. It is not active by default
declined	110	Decline - Velocity/abuse duplicated ID	This feature needs to be enabled for your integration. It is not active by default
resubmission_requested	605	Face missing from image	Upload reference image again to the same session uuid Send the end user to the same url.
resubmission_requested	606	Face is not clearly visible
resubmission_requested	608	Document front missing	Reference image/s not good enough to do face match, try uploading a different document-front image. Send the user to the same url.
resubmission_requested	619	Document data not visible
expired	null	null	Create a new session for the user
abandoned

Face Match Service Flow Diagram

Webhooks

To handle the response from Veriff services, you will need to implement an endpoint that accepts payloads posted by our services. Please note that Veriff does not allow custom ports to be added to the webhook URLs.

Configuring the webhook endpoint

Go to Veriff Station, Integrations -> Find the integration to configure -> Settings, and set one of the webhook URLs to the URL where your endpoint is accepting payloads from Veriff. There are several types of webhooks.
Veriff will post payloads to respective webhook URLs.

If there is a network connectivity issue or technical issue with delivering the notification (any non-200 response code), Veriff will retry the notification once in every hour for up to a week.

Recognizing your customer

When your server receives a payload from Veriff, you need to be able to reference a customer.
There are a couple of ways to do this.

Using the Veriff session ID

The easiest way is to track the session ID provided by Veriff during session creation. All future webhooks payloads refer to the attempt ID. The attempt ID is unique for each session and it can be used to look up sessions in Station interface.

Using your own customer ID

To use your own customer ID you need to provide your internal customer ID to Veriff, or some other key that uniquely identifies your customer. You can store your identifier in the vendorData property during the session creation. Please bear in mind that it is technically possible for one customer to be associated with multiple verification sessions, and this could potentially create ambiguous situations in code, if you are only recognizing customers by your own identifier, and not Veriff's session ID.

Handling security

It is important to check that the webhook responses do indeed originate from Veriff. For that we use the X-HMAC-SIGNATURE header, which value is an HMAC-SHA256 hex encoded keyed hash using your API private key.

Different webhook types

There are several different webhook types to help you to tailor your service specifically to your needs.

• Webhook decisions URL is where we post decisions about verifications (approved, declined, resubmission_required, expired, abandoned, review), see the sample payload
• Webhook events URL is where we post events during the lifecycle of a verification (started, submitted), see the sample payload
• Webhook watchlist screening URL is where we post events related to both the initial and monitored results of the PEP, sanctions, and adverse media checks, see the example payload

Meaning of the various verification responses

Verification status is one of

• approved
• resubmission_requested
• declined
• expired
• abandoned

Verification response code is one of 9001, 9102, 9103, 9104 All codes and explanations can be found from Response and error codes

Explanation of the meaning of the response codes: Meaning of the various event codes

• 9001 : Positive: Person was verified. The verification process is complete. Accessing the sessionURL again will show the client that nothing is to be done here.
• 9102 : Negative: Person has not been verified. The verification process is complete. Either it was a fraud case or some other severe reason that the person can not be verified. You should investigate the session further and read the "reason". If you decide to give the client another try you need to create a new session.
• 9103 : Resubmitted: Resubmission has been requested. The verification process is not completed. Something was missing from the client and she or he needs to go through the flow once more. The same sessionURL can and should be used for this purpose.
• 9104 : Negative: Verification has been expired. The verification process is complete. After 7 days the session get's expired. If the client started the verification process we reply "abandoned" here, otherwise if the client never arrived in our environment the status will be "expired"

Lifecycle of the verification session

Responses 9001, 9102, and 9104 are conclusive responses. The session is closed and the URL is not available for the end user.

Response 9103 is an inconclusive response. The session remains open until you receive one of the above conclusive responses. The session is re-opened for the end user, accepting a new attempt.

Preconditions for approval decisions

We give a positive conclusive decision (status approved, code 9001) when the user has provided us with:

• photos and videos uploaded to us
• the data on the document is readable and matches throughout the document
• the user's portrait photo is recognizable
• the user on the portrait photo corresponds to the person on the document photo
• the document is valid (dates, etc) A positive decision means that the person was verified. The verification process is complete. Accessing the KYC session URL again will tell * the user that nothing more is to be done.

Reasons for negative conclusive decisions

• Physical document not used
• Suspected document tampering
• Person showing the document does not appear to match document photo
• Suspicious behaviour
• Velocity/abuse
• Known fraud

A negative decision means that the person has not been verified. The verification process is complete. Either it was a fraud case or some other severe reason that the person can not be verified. You should investigate the session further and read the "reason". If you decide to give the client another try you need to create a new session.

Reasons for inconclusive decisions

• Video and/or photos missing
• Face not clearly visible
• Full document not visible
• Poor image quality
• Document damaged
• Document type not supported
• Document expired

*In case of verifications which have received a "Resubmission requested" decision from Veriff, we highly recommend notifying the user about the reason why the verification did verification fail and tips for what could be done better on the next attempt. This can be done either via e-mail, SMS and/or in your platform for better visibility. In case of resubmitted verification attempts where something was missing or the quality of the submission was poor, a next attempt is created ready to be used and accessible via the same session URL. The same session URL should be used for verification attempts by the same user.

Final decisions

You have the right to make the final decision about verifying an end-user even after they have completed the verification process with Veriff. In order for you to make the final decision, we recommend you create an appropriate functionality in your back-end. This will enable you to either approve or reject applications after the person has completed Veriff’s verification session. When you perform additional checks outside of Veriff’s service, it is necessary to have another layer of decision making. The decision has to be motivated based on further checks or extra information independent of Veriff’s decision. The additional verification details can be determined in accordance with your business needs and the amount of data and background information available to you about the end-user. Potential use cases: * Age checks * Name validation checks * A user is unable to pass verification as required, but their attempt is sincere and the document is legitimate * A user has made multiple fraudulent attempts to verify and cannot pass Veriff's verification any more * You wish to restrict the user's access to your platform based on their earlier behavior Veriff provides a more standardized solution where unconventional user behavior is not deferred to for the benefit of overall decision quality.

Meaning of the various event codes

{
  "id": "f04bdb47-d3be-4b28-b028-a652feb060b5",
  "feature": "selfid",
  "code": 7002,
  "action": "submitted",
  "vendorData": "QWE123"
}

The event webhook informs you about the progress of the verification. However, it does not inform you of the decision.

The event code can be one of:

• 7001 : Started
• 7002 : Submitted

Storing verification media

For businesses which are regulated by various KYC and AML laws and rules, storing proof of the customer's verification is often a requirement. While Veriff stores and holds the customer's media - photos and videos - it might also be mandatory and more convenient for the business to store this media internally.

First, you need to get the sessionId of a session you want to download the media for. This can be found from the decision webhook(parameter "id") which is automatically sent after a decision has been made for a verification session. With the sessionID, make a GET request to /sessions/{sessionId}/media endpoint. From there, you will find a mediaId for every media file we have stored.

With the mediaIds, you can make a GET request to /media/{mediaId} endpoint to get the media file in .jpeg or .mp4 format. A separate request will have to be made for each media file.

Automating the download of photo and video files associated with completed verifications.

/sessions/{sessionId}/media First, query for a list of files using a GET request to /media/{mediaId} The response to your GET request to /sessions{sessionID}/media will be a list of videos and images related to this sessionID.

Second, the individual media files can be downloaded by using the mediaID returned in the first step with a GET request to /media/{mediaID}

Decision webhook

This is the description of the payload sent to Webhook decisions URL.
The result of the verification is sent back to the vendor once the verification has been processed.

Testing

For testing purposes we provide an example payload so you do not depend on Veriff sending the response. You can use this Curl command. Beware, that the signature will not match your API Public Key and API Private Key. To validate this example signature and payload use API Private Key 'abcdef12-abcd-abcd-abcd-abcdef012345'.

curl --request POST 'https://your.url' -k \
--header 'accept:application/json' \
