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 Settings 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.

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",
        "lang": "en",
        "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

Generating the X-SIGNATURE header

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

The X-SIGNATURE is a SHA-256 hex encoded hash of the concatenation of the request body and your API secret.

To generate the X-SIGNATURE header, please:

• in a temporary buffer, concatenate the request body and your API secret.
• calculate a SHA 256 hash
• hex encode the hash

For example, if the request object is

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

Next, take the request object and add your API-Secret to the end.(replace 'Your-API-Secret' with your API secret)

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

Alternatively, if you use stringified request body then your concatenated payload will look as following.(replace 'Your-API-Secret' with your API secret)

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

Now you will need to calculate a SHA256 hash and hex encode it, as the description of that calculation is in the API spec at #sessions

This process depends on the language you use.

Using JavaScript / ECMA

To view the code sample select the language at the top-right

const payload = JSON.stringify(verification);
const signature = crypto.createHash('sha256');
signature.update(new Buffer(payload, 'utf8'));
signature.update(new Buffer(secret, 'utf8'));
return signature.digest('hex');

Using C# / .Net

To view the code sample select the language at the top-right

string hashString;
using (var sha256 = SHA256Managed.Create())
{
    var hash = sha256.ComputeHash(Encoding.Default.GetBytes(payloadPlusSecret));
    hashString = ToHex(hash, false);
}

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:3.3.0'

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))
        .toolbarIcon(R.drawable.toolbar_icon)
        .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);

The theme color, toolbar and notification icons are optional. If a value is not provided for them the default Veriff theme color, and icons will be used.

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);

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

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

iOS SDK integration

iOS SDK Requirements

Integration Veriff iOS SDK requires at least iOS version 11.0

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"
binary "https://cdn.veriff.me/ios/carthage/VeriffWebRTC.json" == 1.0.1

After a carthage update add Veriff and WebRTC frameworks 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
$(SRCROOT)/Carthage/Build/iOS/WebRTC.framework

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

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

Using XCFramework

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

After files are downloaded, drag VeriffSDK.xcframework and WebRTC.framework 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 and microphone permissions for capturing photos an video during identification. Your application is responsible to describe the reason why camera and microphone is used. You must add 2 descriptions listed below to info.plist of your application with the explanation of the usage.

• NSCameraUsageDescription
• NSMicrophoneUsageDescription

Starting verification flow

Import Veriff in your code

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].

var veriff = VeriffSdk.shared
veriff.startAuthentication(sessionUrl: 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 and logo

You can customize the Veriff user interface through your own application, by letting the SDK know of your brand's main color and logo. The Branding struct allows customization of the theme color and the navigation bar title image. 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.

let yourColor = UIColor.someColor()
let yourImage = UIImage(named: “logo.png”)
let branding = VeriffSdk.Branding(themeColor: yourColor, logo: yourImage)

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.

let locale = Locale(identifier: “et”)

Create the configuration object

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

Start the verification flow by using the configuration

var veriff = VeriffSdk.shared
veriff.startAuthentication(sessionUrl: 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.

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 {
                …
            }
        }
    }
}

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, check the associated value(Veriff.Error) passed by error status.

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 occurences of VeriffConfiguration with VeriffSdk.Configuration.

Branding is now VeriffSdk.Branding

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

Rename VeriffDelegate to VeriffSdkDelegate

Please replace the occurences 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 occurences of sessionToken. You can now use sessionUrl to get the full sessionUrl including token.

iOS SDK Changelog

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

React Native SDK integration

React Native SDK requirements

Integration with Veriff React Native SDK requires the project to target at least iOS version 11.0 and Android version 5.0 (api 21) or higher.

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()
    }
}

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 11.0 or higher:

platform :ios, '11.0'

Also make sure your main target in the Podfile contains both use_frameworks! and use_native_modules! directives at the end:

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

  use_frameworks!
  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 iOS SDK requires camera and microphone permissions for capturing photos an video during identification. Your application is responsible to describe the reason why camera and microphone is used. You must add 2 descriptions listed below to Info.plist of your application with the explanation of the usage.

Add them to the ios/TARGET/Info.plist file:

<dict>
...
    <key>NSCameraUsageDescription</key>
    <string>Access to camera is needed for user identification purposes </string>
    <key>NSMicrophoneUsageDescription</key>
    <string>Access to microphone is needed for video identification</string>
</dict>

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 11.0 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 theme color and navigation bar title image and notification image (Android only) by passing in these optional properties when launching Veriff:

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

When the 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.

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 your own 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 is link 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 graned 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

• Decision webhook with wrong API key should not be accepted
• Decision webhook with mismatched X-SIGNATURE should not be accepted
• Decision 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 (Event endpoint)
• Abandoned (Event 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 sessionURL
• 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 'Your-API-Key' and 'Your-API-Token' 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 || 'Your-api-key'; 
const API_SECRET = process.env.API_SECRET || 'Your-api-token';
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.

Session Status Diagram

API Reference

Requirements

API Key and API token can be found by logged in customers on settings page.

Headers

X-AUTH-CLIENT: string (required) - API Key
CONTENT-TYPE: string (required) - Type for the request: (application/json)
X-SIGNATURE: string (required) - Request Body signed with API Secret.

X-Signature is a SHA-256 hex encoded hash. The stringified body is concatenated by the API Secret and then hex digested.

API URL https://stationapi.veriff.com/v1

Note: Headers are sent with each request

Lifecycle of a verification:

Endpoints

In this post request the vendor sends the data of the client to Veriff and in return, recieves a unique sessionToken that is related to the client. You can find the sample implementation for Javascript. https://github.com/Veriff/js-integration-demo

The URIs have the following structure:

https://<Base-URL>/v1/

For example, https://your-veriff-baseUrl/v1/sessions/

Note: to get Base URL choose Integrations in the top menu of Veriff Station, then integration you need.

Available endpoints and methods:

• /sessions
  • /sessions /{sessionId}
  • /sessions/{sessionId} /media GET
  • /sessions/{sessionId} /media POST
  • /sessions/{sessionId} /person
  • /sessions/{sessionId} /attempts
  • /sessions/{sessionId} /decision
• /media /{mediaId}
• /attempts

/sessions

Request Properties explained:

• verification : object (required) Verification object
  • callback: String - default is defined on settings - Callback url to which the client is redirected after the verification session is completed
  • person: object - Person to be verified
    • firstName: String - First name
    • lastName: String - Last name
    • idNumber: String - National identification number
    • gender: String - Gender
  • document: object - Document of a person to be verified
    • number: String - Document number
    • country: ISO-2 - String Issuing country of the document
    • type: PASSPORT - (PASSPORT, ID_CARD, DRIVERS_LICENSE, RESIDENCE_PERMIT) Document type
  • additionalData: object (This field is deprecated , not actively used by Veriff) - Data from the filled application. JSON object should not have any nested objects it’s just simple key value pair
  • vendorData: string - Vendor specific data string, max 400 characters long, will be sent back unmodified using webhooks
  • lang: String - Language of end user flow. ISO 639-1 codes are being used.

  • 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-Signature

Signing requests

It is important to check that the webhook responses do indeed originate from Veriff.

You can secure the webhook listener URL in three ways:

have a good secure SSL server for your webhook listener (Veriff will call only to HTTPS URLs, to servers with a publicly verifiable certificate) check the X-AUTH-CLIENT and X-SIGNATURE headers on the decision webhook (the signature is calculated using the API secret that only you and Veriff know) finally, if you are really suspicious, 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).
When Veriff calls your webhook endpoint, we use the same logic of X-SIGNATURE generation on our calls to you, as on your calls to us. So, when we call your endpoint for any notification URL, we set the X-AUTH-CLIENT http header to your API key, and we set the X-SIGNATURE header to the hex encoded sha256 digest of the request body and the secret.

When you accept a webhook call from us, you need to proceed as follows:

Compare the X-AUTH-CLIENT header to your api key, if different -> fail with error access the http request body (before it is parsed) calculate the sha256 digest of the request body string + api secret compare the hex encoded digest with the X-SIGNATURE header, if different -> fail with error only now you should parse the request body JSON object The calculation for X-SIGNATURE is following the same algorithm as for session generation.

Generating X-Signature:

Here are few examples how to do it.

NodeJS

const crypto = require('crypto');

// Globals
const API_KEY = 'Your-api-key';
const API_SECRET = 'Your-api-secret';

const data = 'my precious data';

// Headers 
const headers = 
   { 'Content-Type': 'application/json',
     'X-AUTH-CLIENT': API_KEY,
     'X-SIGNATURE': generateSignature(data, API_SECRET) };


function generateSignature(payload, secret, error) {
  if (payload.constructor === Object) {
    payload = JSON.stringify(payload);
  }

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

  const signature = crypto.createHash('sha256');
  signature.update(payload);
  signature.update(new Buffer.from(secret, 'utf8'));
  return signature.digest('hex');

};

console.log(headers);

Python3

import hashlib
import json

#Globals
API_KEY = 'Your-api-key'
API_SECRET = 'Your-api-secret'
payload=json.dumps({'my precious data':'goes here'})            

def generateSignature(payload, secret): 
  sha_signature = \
      hashlib.sha256(f'{payload}{secret}'.encode()).hexdigest()
  return sha_signature

print(generateSignature(payload, API_SECRET))

Manual Generation:

Create session with following payload via API. Sometimes you might want to use Postman or any other tool for API testing. For this you will need to manually calculate sha-256 hash from payload and send it with X-signature header Keep in mind that if you stringify payload body then you will need to sign stringified payload at hash calculation step as well.

{
    "verification": {
        "callback": "https://veriff.com",
        "person": {
            "firstName": "John",
            "lastName": "Smith",
            "idNumber": "1234567890"
        },
        "document": {
            "number": "B01234567",
            "type": "PASSPORT",
            "country": "EE"
        },
        "vendorData": "11111111",
        "lang": "en",
        "timestamp": "2016-05-19T08:30:25.597Z"
    }
}

First take the payload and add your API-Secret to the end. (replace 'Your-API-Secret' with your API secret) Note: current example can be encoded using "Your-API-Secret" for manual calculation

{
  "verification": {
      "callback": "https://veriff.com",
      "person": {
          "firstName": "John",
          "lastName": "Smith",
          "idNumber": "1234567890"
      },
      "document": {
          "number": "B01234567",
          "type": "PASSPORT",
          "country": "EE"
      },
      "vendorData": "11111111",
      "lang": "en",
      "timestamp": "2016-05-19T08:30:25.597Z"
  }
}Your-API-Secret

Use your favorite SHA-256 hash calculator to calculate hash.
E.g https://xorbin.com/tools/sha256-hash-calculator

SHA-256 hash is: 4f6a803b432dae66340ea7aba816527f0ccac2e8956c3f3db37510eca1177941

X-Signature included to your request headers is above hash:

Headers

Content-Type: application/json  
X-AUTH-CLIENT: Your-API-Key 
X-SIGNATURE: fae37e40c27875f52f944a39d37540d6d32ab4c39bf004c5e107925e44c7c05a

Validating X-Signature:

We sign all responses using same logic. Response body + Your-API-Secret = X-SIGNATURE in response headers.
To be sure that response is sent by Veriff you can validate X-SIGNRATURE.

Here are few examples how to do validate response signature. Below is function you can use.

NodeJS

function isSignatureValid(data) {
  const { signature, secret } = data;
  let { payload } = data;

  if (data.payload.constructor === Object) {
    payload = JSON.stringify(data.payload);
  }
  if (payload.constructor !== Buffer) {
    payload = new Buffer.from(payload, 'utf8');
  }
  const hash = crypto.createHash('sha256');
  hash.update(payload);
  hash.update(new Buffer.from(secret));
  const digest = hash.digest('hex');

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

Validate from response:

Easiest way to test validation function is to setup webhook listnener on localhost and do use cURL for quick validation test. This way you can test your function independently from our Webhook or API responses.

Step 1 - Setup webhook listsener and validate payload.

NodeJS

const crypto = require('crypto');
const request = require("request");
const express = require('express');
const bodyParser = require('body-parser');
const app = express();

const WEBHOOK_PORT = 3001;
const API_SECRET = 'Your-API-Secret';

function isSignatureValid(data) {
  const { signature, secret } = data;
  let { payload } = data;

  if (data.payload.constructor === Object) {
    payload = JSON.stringify(data.payload);
  }
  if (payload.constructor !== Buffer) {
    payload = new Buffer.from(payload, 'utf8');
  }
  const hash = crypto.createHash('sha256');
  hash.update(payload);
  hash.update(new Buffer.from(secret));
  const digest = hash.digest('hex');

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

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

app.post('/verification/', (req, res) => {
  const signature = req.get('x-signature');
  const secret = API_SECRET;
  const payload = req.body;

  console.log('Received a webhook');
  console.log('Is signature valid:', isSignatureValid({ signature, secret, payload }));
  console.log('Payload', JSON.stringify(payload, null, 4));
  res.json({ status: 'success' });
  process.exit();
})

server.listen(WEBHOOK_PORT);
console.log('Server is UP \n Listsening port:', WEBHOOK_PORT);

Step 2 - Post some data to webhook listener for validation:

Below will return: Is signature valid: true if you use 'Your-API-Secret' for validating signature.

CURL

Webhooks

To automate the handling of responses from verifications, you will need to implement a webhook listener, according to the documentation at Webhook Decision (POST). Determine the URL of the listener, also, take into account that Veriff doesn't allow custom ports to be added to the webhooks urls (neither on decisions nor on events). Once the URL is determined it can be configured in the Veriff Station under Integrations › Webhook Decision / Events URL. In case you want to test web hooks before the mobile app fully working, it is possible to manually generate verification session in Station and then following the URL for a web-based verification session, which will post the result to your webhook.

Configuring the webhook endpoint

Go to Veriff's back office, Management -> Vendors -> Edit, and set 'Decision notification url' to the URL where your server will be listening for decision notifications from Veriff. Veriff will post decision notifications of verification results to this URL. Only HTTPS URLs are allowed.

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

The full description of the webhook format is at Webhook Decision (POST)

Recognizing your customer

When your server receives a decision notification from Veriff, you have to figure out, which customer is it about.

There are two ways to do this:

• using the Veriff session ID, or
• using your own customer ID.

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

The other way is to provide Veriff with your internal customer ID, or some other key that uniquely identifies your customer. You can store your identifier in the vendorData element as a string, and we will send it back to you in webhook notifications. 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.

You can secure the webhook listener URL in three ways:

• have a good secure SSL server for your webhook listener (Veriff will call only to HTTPS URLs, to servers with a publicly verifiable certificate)
• check the X-AUTH-CLIENT and X-SIGNATURE headers on the decision webhook (the signature is calculated using the API secret that only you and Veriff know)
• you may also restrict your webhook listener to only accept calls from the Veriff IP range (please ask your Veriff integration onboarding specialist for those details)

When Veriff calls your webhook endpoint, we use the same logic of X-SIGNATURE generation on our calls to you, as on your calls to us. So, when we call your endpoint for any notification URL, we set the X-AUTH-CLIENT http header to your API key, and we set the X-SIGNATURE header to the hex encoded sha256 digest of the request body and the secret.

When you accept a webhook call from us, you need to proceed as follows:

1. compare the X-AUTH-CLIENT header to your api key, if different -> fail with error
2. access the http request body (before it is parsed)
3. calculate the sha256 digest of the request body string + api secret
4. compare the hex encoded digest with the X-SIGNATURE header, if different -> fail with error
5. only now you should parse the request body JSON object

The calculation for X-SIGNATURE is following the same algorithm as for session generation.

Different webhook calls

The difference between the URLs is as follows:

• the Decision Webhook Url is where we post decisions about verifications (approved, declined, resubmission_required, expired, abandoned, etc)
• the Event Webhook Url is where we post events during the lifecycle of a verification (started, submitted, etc)
• finally, there is a Callback URL, which is actually the redirect URL for the user on the web site at the end of KYC

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: Webhook response 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 video 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 verificaton 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 attemtps 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}

/webhooks /decision (POST)

This endpoint specifies how the asynchronous response to the notification url looks like. It sends the result of the verification back to the vendor once the verification has been reviewed. The notification url needs to be specified in Veriff's backoffice.

Response

Description For testing this endpoint without depending on Veriff sending responses you can use this Curl command. Beware, that the signature will not match your Vendors Key and Secret. To validate this example signature and payload use Secret '3c184872-6929-43d9-91d5-9e68468b5aa1'.
