Check-Driven Integration

Integrate the Android SDK using a check-driven approach.

Overview

This guide walks you through integrating the Android SDK with ComplyCube using the check-driven approach, giving you direct control over individual verification steps.

You’re viewing the check-driven SDK guide - an approach that provides detailed control but is best suited for partners or advanced use cases. We recommend using workflow integration for most implementations.

Integration flow

The Mobile SDK runs on your mobile application, but relies on your backend to create secure tokens. Here’s how it works:

Create a client

Generate an SDK token

Your backend requests a JWT token tied to that client.

Initialize the SDK in your mobile app

Pass the token and settings to the SDK initializer.

Capture documents, videos, and selfies

The SDK guides your customer through the required steps.

Perform checks

Captured data is securely sent to ComplyCube for verification checks, and results are delivered in real time through the API or webhooks.

Integration guide

Explore the source code and sample projects on our repository: .

Install the SDK

Our SDK requires the repositories below.

repositories {
  mavenCentral()
}

dependencies {
    implementation "com.complycube:complycube-sdk:+"
}

Create a client

Every verification flow starts with a client (i.e. customer). Use the API to create the client.

This must be done on your mobile app backend server, not the mobile app itself.

Example request

curl -X POST https://api.complycube.com/v1/clients \
     -H 'Authorization: <YOUR_API_KEY>' \
     -H 'Content-Type: application/json' \
     -d '{
          "type": "person",
          "email": "[email protected]",
          "personDetails":{
               "firstName": "John",
               "lastName" :"Doe"
          }
        }'

const { ComplyCube } = require("@complycube/api");

const complycube = new ComplyCube({ apiKey: "<YOUR_API_KEY>" });

const client = await complycube.client.create({
  type: "person",
  email: "[email protected]",
  personDetails: {
    firstName: "John",
    lastName: "Doe"
  }
});

from complycube import ComplyCubeClient
cc_api = ComplyCubeClient(api_key='<YOUR_API_KEY>')

new_client = {
    'type':'person',
    'email':'[email protected]',
    'personDetails': {
        'firstName':'John',
        'lastName':'Doe'
    }
}

client = cc_api.clients.create(**new_client)

use ComplyCube\ComplyCubeClient;

$ccapi = new ComplyCubeClient('<YOUR_API_KEY>');

$result = $ccapi->clients()->create([
    'type' => 'person',
    'email' => '[email protected]',
    'personDetails' => [
        'firstName' => 'John',
        'lastName' => 'Doe'
    ]
]);

using ComplyCube.Net;
using ComplyCube.Net.Resources.Clients;

var clientApi = new ClientApi(new ComplyCubeClient("<YOUR_API_KEY>"));
var newClient = new ClientRequest {
  type = "person",
  email = "[email protected]",
  personDetails = new PersonDetails {
    firstName = "John",
    lastName = "Doe"
  }
}

var client = await clientApi.CreateAsync(newclientRequest);

Example response

The response will contain an id (the Client ID). It is required for the next step.

{
    "id": "5eb04fcd0f3e360008035eb1",
    "type": "person",
    "email": "[email protected]",
    "personDetails": {
        "firstName": "John",
        "lastName": "Doe",
    },
    "createdAt": "2020-01-04T17:24:29.146Z",
    "updatedAt": "2020-01-04T17:24:29.146Z"
}

See Clients API Reference to learn more.

Generate an SDK token

Your backend must create an SDK token for each new flow. This token enable customers to send personal data securely from your mobile app to ComplyCube.

Tokens are short-lived and must not be reused.

Example request

curl -X POST https://api.complycube.com/v1/tokens \
     -H 'Authorization: <YOUR_API_KEY>' \
     -H 'Content-Type: application/json' \
     -d '{
           "clientId":"CLIENT_ID",
           "appId": "com.complycube.SampleApp"
         }'

const { ComplyCube } = require("@complycube/api");

const complycube = new ComplyCube({ apiKey: "<YOUR_API_KEY>" });

const token = await complycube.token.generate("CLIENT_ID", {
    appId: "com.complycube.SampleApp"
});

using ComplyCube.Net;
using ComplyCube.Net.Resources.SDKTokens;

var sdkTokenApi = new SDKTokenApi(new ComplyCubeClient("<YOUR_API_KEY>"));

var sdkTokenRequest = {
  clientId = "CLIENT_ID",
  appId = "com.complycube.SampleApp"
}

var sdkToken = await sdkTokenApi.GenerateToken(sdkTokenRequest);

Example response

{
    "token": "<CLIENT_TOKEN>"
}

See SDK Token API Reference to learn more.

Prepare the stages

Set up the stages you wish to include in your flow.

val complyCubeBuilder = ComplyCubeSdk.Builder(this, callback =  { }).apply {
    withStages(
        Document(
            identityDocumentType = Passport(), DrivingLicence(),
            useLiveCaptureOnly = false
        ),
        SelfiePhoto()
    )
}

IdentityDocumentType[] identityDocumentTypes;

identityDocumentTypes = new IdentityDocumentType[1];

identityDocumentTypes[0] = new DrivingLicence();

Document document = new Document(
    // documentType
    null,
    // documentTypes
    identityDocumentTypes,
    // isGuidanceEnabled
    true,
    // useLiveCaptureOnly
    false,
    // isMLAssistanceEnabled
    true,
    // retryLimit
    5,
    // isNFCEnabled
    true
);

Initialize the SDK

You can now initialize a flow. The sequence of stages you specify determines the order in which your client sees those stages.

val complyCubeBuilder = ComplyCubeSdk.Builder(this, callback =  { }).apply {
    withStages(
        Document(
            identityDocumentType = Passport(), DrivingLicence(),
            useLiveCaptureOnly = false
        ),
        SelfiePhoto()
    )
}.start(
    ClientAuth(
        token = "SDK_TOKEN",
        clientId = "CLIENT_ID"
    )
)

ComplyCubeSdk.Builder complycubeFlow =
    new ComplyCubeSdk.Builder(this, result - > {});

complycubeFlow.withStages(
    document,
    new SelfiePhoto()
);

complycubeFlow.start(new ClientAuth(
    "SDK_TOKEN",
    "CLIENT_ID"
));

Perform checks

Using the StageResults returned by the flow, you can trigger your mobile backend to run the necessary checks on your client.

For example, use the result of a selfie and document capture as follows:

StageResult.Document.Id to run a Document Check.
StageResult.Document.Id and StageResult.LivePhoto.Id to run an Identity Check.

Example request for a Document Check

curl -X POST https://api.complycube.com/v1/checks \
     -H 'Authorization: <YOUR_API_KEY>' \
     -H 'Content-Type: application/json' \
     -d '{
            "clientId":"CLIENT_ID",
            "type": "document_check",
            "documentId":"DOCUMENT_ID"
         }'

const { ComplyCube } = require("@complycube/api");

const complycube = new ComplyCube({ apiKey: "<YOUR_API_KEY>" });

const check = await complycube.check.create("CLIENT_ID", {
    type: "document_check",
    documentId: "DOCUMENT_ID"
});

use ComplyCube\ComplyCubeClient;

$ccapi = new ComplyCubeClient('<YOUR_API_KEY>');

$result = $ccapi->checks()->create('CLIENT_ID', [
    'type' => 'document_check',
    'documentId' => 'DOCUMENT_ID'
]);

using ComplyCube.Net;
using ComplyCube.Net.Resources.Checks;

var checkApi = new CheckApi(new ComplyCubeClient("<YOUR_API_KEY>"));

var checkRequest = new CheckRequest {
  clientId = "CLIENT_ID",
  type = "document_check",
  documentId = "DOCUMENT_ID"
};

var check = await checkApi.CreateAsync(checkRequest);

If you have set up webhooks as described in our webhooks guide, you will be notified once a check completes.

To retrieve the check results, you can perform a get check request.

Retrieve verification results

Your mobile backend can retrieve all check results using our API.

All our checks are asynchronous. If you have set up webhooks as described in our webhooks guide, you will be notified once a check completes.

To retrieve the check results, you can perform a get check request.

Example request

curl -X GET https://api.complycube.com/v1/checks/{:checkId} \
     -H 'Authorization: <YOUR_API_KEY>'

Stages

Each stage in the flow can be customized to create the ideal journey for your customers.

The snippet below demonstrates how to set up a customized flow using the ComplyCube Mobile SDK.

var complycubeFlow = ComplyCubeSdk.Builder(this, callback = ...)
  .withSDKToken("SDK_Token")
  .withClientId("CLIENT_ID")
  .withStages(
    Welcome(...),
    Consent(...),
    Document(...),
    SelfiePhoto(...),
    AddressCapture(...),
    ProofOfAddress(...),
    Complete(...)
  )
  .withLookAndFeel(...)
  .withCustomLanguage(...)

complycubeFlow.start()

complycubeFlow.withStages(
    new Welcome(...),
    new UserConsent(...),
    new Document(...),
    new SelfiePhoto(...),
    new AddressCapture(...),
    new ProofOfAddress(...),
    new Complete(...)
);

complycubeFlow.withLookAndFeel(...);
complycubeFlow.withCustomLanguage(..);

Welcome

The Welcome screen is always shown first in the verification flow. It displays a welcome message along with a summary of the configured stages the user will complete.

You can customize the screen title to align with your app’s tone and branding.

var welcomeStage = Welcome(
    title = "Custom Screen Title",
    message = "Custom welcome message."
)

This stage is used to collect explicit user consent before proceeding with the verification flow. It helps you meet regulatory and compliance requirements where applicable.

You can customize the screen title and message to match your legal or branding needs.

var consentStage = Consent(
    title = "Custom Consent Screen Title"
)

Selfie photo and video

You can request either a selfie photo (i.e. a Live Photo) or a selfie video (i.e. a Live Video) from the customer as part of the biometric verification process.

Photo: Captures a still image and performs a passive liveness check before allowing submission.
Video: Records a short video where the user completes an on-screen challenge (e.g. head movement or spoken phrase).

If you attempt to add both types of stages, the SDK will throw a ComplyCubeErrorCode.BiometricStageCount error stating multiple conflicting stages.

var selfiePhoto = SelfiePhoto(
    // Enable ML assistance during capture
    isMLAssistantEnabled = false
)

var selfieVideo = SelfieVideo(
    // Enable ML assistance during capture
    isMLAssistantEnabled = false
)

Document

The Document stage allows users to select and capture an identity document for verification (e.g. passport, ID card, residence permit). You can customize these screens to:

Limit the scope of document types the client can select, e.g., Passport only.
Set the document issuing countries they are allowed for each document type.
Add or remove automated capture using smart assistance.
Show or hide the instruction screens before capture.
Set a retry limit to allow clients to progress the journey regardless of capture quality.

If you provide only one document type, the document type selection screen will be skipped. The country selection screen will be skipped if you provide only a single country for a given document type.

You can control whether instructional screens are shown before each camera capture by enabling or disabling guidance mode. Only disable guidance if your users are already clearly informed about the capture steps, as these screens help reduce user error and improve capture quality.

Please note the retryLimit you set here will take precedence over the retry limit that has been set globally in your automation settings.

var documentStage = Document(
    // Set document types and limit the enabled countries
    Passport(), DrivingLicence((Country.GB, Country.US)),

    // Enable or disable additional guidance for the user
    isGuidanceEnabled = true,

    // Enable or disable the ability to upload an image from file
    useLiveCaptureOnly = true,

    // Enable ML assistance during capture
    isMLAssistantEnabled = true,
    
    // Set a maximum for quality check attempts before uploadingoft checks
    retryLimit = 3
)

IdentityDocumentType[] identityDocumentTypes;

identityDocumentTypes = new IdentityDocumentType[1];

identityDocumentTypes[0] = new DrivingLicence();

Document document = new Document(
    null,
    identityDocumentTypes, // documentTypes
    true, // isGuidanceEnabled
    false, // useLiveCaptureOnly
    true, // isMLAssistanceEnabled
    5, // retryLimit
    true // isNFCEnabled
);

NFC capture

The ComplyCube mobile SDK supports NFC-based RFID chip reading for identity documents equipped with embedded chips. This allows for secure data extraction and high-assurance document authentication.

Please get in touch with your Account Manager or support to get access to our NFC-enabled Mobile SDK.

Pre-requisites

Start by adding your access credentials for the ComplyCube NFC-Enabled SDK repository to the gradle.properties file of your mobile app:

artifactory_user= "USERNAME"
artifactory_password= "ENCRYPTED PASS"
artifactory_contextUrl= https://complycuberepo.jfrog.io/artifactory

Then, update your project level build.gradle file with the ComplyCube SDK repository Maven settings:

buildscript {
    repositories {
        ...
    }
    dependencies {
        ....
        // Check for the latest version here: 
        // http://plugins.gradle.org/plugin/com.jfrog.artifactory
        classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4+"
    }
    ...
}

allprojects {
    apply plugin: "com.jfrog.artifactory"
    ...
}

artifactory {
  contextUrl = "${artifactory_contextUrl}"  
  resolve {
    repository {
      repoKey = 'cc-gradle-release'
      username = "${artifactory_user}"
      password = "${artifactory_password}"
      maven = true
    }
  }
}

Update your module level build.gradle file with the SDK dependency:

dependencies {
    implementation "com.complycube:complycube-sdk:+"
    implementation "com.complycube:nfc-plugin:+"
}

Enabling NFC capture

var documentStage = Document(
    // Add this property to enable NFC
    isNFCEnabled = true,
)

IdentityDocumentType[] identityDocumentTypes;

identityDocumentTypes = new IdentityDocumentType[1];

identityDocumentTypes[0] = new Passport();

Document document = new Document(
    null,
    // documentTypes
    identityDocumentTypes,
    // isGuidanceEnabled
    true,
    // useLiveCaptureOnly
    false,
    // isMLAssistanceEnabled
    true,
    // retryLimit
    5,
    // isNFCEnabled
    true
);

Address capture

This stage allows users to manually enter their residential address. You can customize it to:

Restrict input to specific countries
Enable or disable the address autocomplete feature for faster and more accurate entry

var addressCaptureStage = AddressCapture(
    // This enables our address autocomplete
    useAutoComplete = true,
    
    // A list of acceptable countries for address capture feature
    allowedCountries = setOf(Country.GB,Country.US)
)

Set<Country> countries = new HashSet<> ();

countries.add(Country.GB);
countries.add(Country.US);

AddressCapture addressCapture = new AddressCapture(
    // useAutoComplete
    true,
    // allowedCountries
    countries
);

Proof of address

This stage allows customers to submit a document verifying their residential address. You can configure which document types are accepted, such as utility bills or bank statements, and choose whether customers can upload a file or must capture the document live using their device camera.

By default, this stage includes the address capture stage with autocomplete enabled to assist users during entry. Autocomplete can be disabled if not required.

var poaStage = ProofOfAddress(
    // A list of supported document types that can be submitted
    UtilityBill(), BankStatement(),

    // When disabled, the client will be forced to perform a live capture
    useLiveCaptureOnly = false,

    // This enables address capture during the proof of address flow
    isAddressCaptureEnabled = false
    ...
)

LinkedHashSet<ProofOfAddressDocumentType> documentTypes =
    new LinkedHashSet<ProofOfAddressDocumentType> ();

documentTypes.add(new UtilityBill());
documentTypes.add(new BankStatement());

ProofOfAddress poaStage = new ProofOfAddress(
    documentTypes,
    // isGuidanceEnabled
    true,
    // useLiveCaptureOnly
    false,
    // isMLAssistanceEnabled
    true,
    // retryLimit
    5,
    // isAddressCaptureEnabled
    false
);

Completion

You can include a completion stage at the end of the flow to confirm that the process has been successfully finished. This screen provides a clear end point for the user and can be customized to display a confirmation message or next steps.

val completionStage = Complete(
    title = "Thank you!",
    message = "Your KYC submission has been completed"
)

Branding

The SDK allows you to customize the UI to match your application’s visual identity. You can define primary and accent colors during configuration to align the verification flow with your brand guidelines. Learn more about our appearance properties (see below).

complycubeFlow.withLookAndFeel(
    lookAndFeel = LookAndFeel(
        primaryButtonBgColor = Color.RED,
        /* Can also be set to UIInterfaceStyle.LIGHT 
        or UIInterfaceStyle.INHERITED */
        uiInterfaceStyle = UIInterfaceStyle.DARK
    )

Result handling

To run verification checks, you must implement the success, cancelled, and error callbacks.

On a successful completion (onSuccess), you can trigger check requests from your backend using the resource IDs returned in the result object. These IDs correspond to the uploaded assets (e.g. documents, selfies) and can be used to initiate verification checks via the ComplyCube API.

If the user exits the flow before completion, the onCancelled callback is invoked with a descriptive reason indicating why the session was cancelled (e.g. user exit, timeout, permission denied)

In some cases, the customer may cancel the flow after completing one or more capture stages. If this occurs, any data captured prior to cancellation, such as documents or biometric media, may have already been uploaded to their client record.

If the SDK encounters an issue, the onError callback is triggered with a ComplyCubeError object containing the error type and message. Refer to the error codes (see below), for a full list of possible error cases.

//Register a result handler to process the outcome of the flow.
var complycubeFlow =
    ComplyCubeSdk.Builder(
        this,
        callback = { result ->
            when (result) {
                is Result.Success -> { 
                /*
                Handling successful results:

                a Selfie (Live Photo), and a Proof of Address. Upon successful 
                completion, the 'Result' will contain an array of stage results.
                Each stage result provides the ID of the uploaded item:
                  - 'StageResult.Document.Id': the uploaded Document ID.
                  - 'StageResult.LivePhoto.Id': the uploaded Live Photo ID.
                  - 'StageResult.ProofOfAddress.Id': the uploaded PA Document ID.
                */
                }
                is Result.Cancelled -> { /* Handle Cancelled result */ }

Token expiry handling

To handle token expiration gracefully, you can provide a callback function that generates a new SDK token when needed. This allows the flow to continue seamlessly without requiring the user to restart the session manually.

var complyCubeBuilder = ComplyCubeSdk.Builder(this,
    callback = { result ->
        if (result is Result.Error) {
            if (result.errorCode is ComplyCubeErrorCode.ExpiredToken) {
                // Insert custom token renewal code here
            }
        }
    }
)

ComplyCubeSdk.Builder complyCubeBuilder =
    new ComplyCubeSdk.Builder(this, result - > {
        if (result instanceof Result.Error) {
            if (((Result.Error) result).getErrorCode() == ComplyCubeErrorCode.ExpiredToken.INSTANCE) {
                // Insert custom token renewal code here
            }
        }
        return null;
    });
