Integration Guide

This guide walks you through the steps to integrate Reap’s KYC workflow using SumSub’s WebSDK. By the end, your users will be verified and ready to use downstream services such as Card Issuance

🚀 Step-by-Step Integration

1. Generate an API Key

Where: Reap Card Issuance Dashboard → Settings -> Product Settings -> KYC API Keys
What you get: A Sandbox API key linked to a Business UUID (BUUID).

Use this key for authentication in all API requests. The BUUID scopes all activity to your business.

2. Create an Entity (Applicant)

Endpoint: POST /entities

Register a new user by creating an entity of type INDIVIDUAL.

  • externalId: An ID to identify your user (i.e userID in your database)
  • type: INDIVIDUAL

Response:
Returns a unique entityId used in all further steps.

3. Generate SumSub WebSDK Token

Endpoint: POST /entities/{entityId}/kyc
Generate a WebSDK token to launch SumSub’s identity verification UI

Response:
Returns a WebSDK token to initialize SumSub on your frontend.

Then, go through steps highlighted in SumSub WebSDK Integration Doc to set up frontend integration

Users complete:

  • Identity document verification
  • Liveness check

Reap handles the backend verification and status updates

4. Generate Signed Payload

Endpoint: POST /entities/{entityId}/signed-payload

Once KYC is complete, call this to get a signed payload for the verified entity.

Response:
Returns a signed JWT payload which proves the user passed KYC.

Use this payload to interact with other Reap products (e.g. Create Card in CaaS)

5. Pass Signed Payload to Create Card

Refer to CaaS API documentation

Endpoint: POST /cards

Once signed JWT payload is generated, it can be used to verify KYC status when creating a card for the user. Pass this signed payload in POST /cards kyc object and customerType = Consumer
