Obtain an access token using client credentials

Learn how to retrieve an access token using the OAuth 2.0 client credentials grant type in Postman.

You need a valid Reltio Client ID and Client Secret. These are typically generated in Reltio Console under your application's OAuth configuration. Ensure your client is authorized for the correct scopes and environments.

Use these steps to generate an access token using the OAuth 2.0 client credentials grant type in Postman. This token is required to authenticate API requests in Reltio.

In Postman, open your request and go to the Authorization tab.
Set the Type to OAuth 2.0.
Select Get New Access Token and configure the token settings:
- Token Name: Any descriptive name
- Grant Type: Client Credentials
- Access Token URL: https://auth.reltio.com/oauth/token
- Client ID: Your client ID
- Client Secret: Your client secret
- Scope: Leave blank (unless required by your tenant)
- Client Authentication: Send client credentials in body
SelectGet New Access Token at the bottom of the dialog.
Select Use Token to apply the token to your request.

Note: The token is issued by a centralized Reltio authentication service and is not tenant-specific. As a result, IP whitelisting is not enforced when retrieving the token. However, when you use this token to access tenant-specific APIs (for example, /entities/_scan), IP whitelisting is enforced. If your request comes from a non-whitelisted IP, it will fail with a 403 Forbidden error, even with a valid token.

The token is now applied to your request. You can send API requests to Reltio endpoints with this token. The token typically expires after one hour.
