B2B – Request New Onboarding API

This API allows a B2B client to start a new onboarding session for a specific user under a specific integration. The API returns a generated onboarding link that can be delivered to the end user. The API is authenticated using an OAuth 2.0 Client Credentials access token.

Security Model

The B2B Request New Onboarding API uses the OAuth 2.0 Client Credentials grant type — a server-to-server authentication pattern intended for trusted backend systems. Unlike the Authorization Code flow, this grant does not involve a user-facing login step. Instead, your server authenticates directly using a client_id and client_secret to obtain an access token, which is then used to authorize API requests.

A Client Credentials integration is created automatically for organizations that have Integration Ecosystem enabled.

Find the Client ID & Client Secret

To view the integration details in Dashboard:

1. In the left navigation, go to Integrations.
2. On the Custom tab, click Default client credentials integration.

3. Copy the Client ID to use in the access token request.
4. Click Generate to create the Client Secret. Copy it to use in the access token request. The secret is shown and copyable only once. Store it securely in a secrets manager or vault. If lost, you must generate a new one.

Step 1: Obtain an Access Token

Before calling the B2B onboarding endpoint, your backend must obtain a Bearer token from the Incode authorization server using the Client Credentials grant.

Endpoint: POST {auth-server-url}/oauth2/token

Environment URLs

Request Parameters

Example Request

POST {auth-server-url}/oauth2/token HTTP/1.1
Content-Type: application/x-www-form-urlencoded
grant_type=client_credentials&client_id={clientId}&client_secret={secret}&scope=openid

A successful response returns an access_token to be used as a Bearer token in Step 2.

Step 2: Call the B2B Request New Onboarding Endpoint

Use the access token obtained in Step 1 to call the onboarding endpoint.

Endpoint: POST {base-api-url}/omni/b2b/onboarding/request-new

Environment URLs

Headers

• Authorization: Bearer <access_token>
• Content-Type: application/json
• x-api-key: {api_key}
