Authenticate
OAuth 2.0 is a popular protocol for authorization. This controls entry to our system and ensures that only authorized entities can access our APIs and other protected resources. The information you enter into our authentication system is confidential and can never be accessed from any other Cross River applications.
Our system authenticates machine clients and authorizes them to talk to our APIs.
The Cross River Integration Team provides you with a client_id and a client_secret that you use when requesting an access token. You can use a web-based tool, like Postman, to send API requests.
HTTP component | Attribute | Description |
|---|---|---|
Endpoint | POST /connect/token | Endpoint for retrieving an access token |
Header | content-type | application/x-www-form- urlencoded |
Body | grant_type | This field will always have a value of client_credentials Secrets cannot be recovered by CR. If you lose a secret, a new one must be generated. |
Body | scope | A specific range of services that a user can access. - If the required scope is missing the subsequent API call will be returned as forbidden (403). - If a scope isn't specified, the token returned will contain all scopes associated with your credentials. Note: Multiple scopes can be sent in the same request by adding a space between the name of each scope. For example: 'scope=scope1 scope2 scope3' |
Body | client_id | The unique identifier for a client |
Body | client_secret | An encrypted string of characters used to sign and validate ID tokens. IMPORTANT: Do not commit your secrets into source control |
When you've successfully authenticated, an access_token will be returned to you. The access token allows you to send information securely as a JSON object for use in our APIs. Add this token to the header of your API calls.
IMPORTANT Protect your token. Don't log them. Anyone who steals your token can impersonate your client for the lifetime of the token.

Attribute | Description |
|---|---|
access_token | A digitally signed JSON web token (JWT) sent from the oAuth server that allows access to specific Cross River resources |
scope | A range of services that a user can access |
expires_in | The amount of time until the token expires. - Our Integration Team will inform you of the expiration time or you can decode your access token as well. - We recommend that you retrieve a new access token a short time before the old token is set to expire. - Reuse tokens for their entire lifespan rather than getting a new token for each call to the same protected resource (API). IMPORTANT: Never decode your token on a publicly hosted website |
token-type | Bearer token |
If the authentication is successful, the Status code is OK.
Sandbox URL: https://oauthtest.crbnj.net/connect/token
You can test the authorization and authentication into our systems with this endpoint, GET /api/SignupCard/TestOauth.
If the authentication token is valid, it will return a 200. If the authentication token isn't valid, it will return a 401.
If you unable to get a bearer token and you haven't received one in the past:
- Confirm the URL.
- Check that the client_id and client_secret are typed correctly. They are case sensitive.
- Check your client_id and client_secret against the one you received.
- Make sure there are no network or allowlist issues.
