# CLIENT\_SECRET\_POST Setup

Authentication requirements for the token endpoint are set by the application's `tokenEndpointAuthMethod` property. When the application's `tokenEndpointAuthMethod` is set to `CLIENT_SECRET_POST`, the request does not need an `Authorization` header, and the `client_id` and `client_secret` property values are submitted in the request body.

**Key points**

* Credentials in POST body: `client_id` and `client_secret` parameters

* No Authorization header needed

* Easier for frameworks that don't handle headers well

* Still requires secure transport (HTTPS)

The following workflow shows the application configuration to complete a sign-on flow using the `CLIENT_SECRET_POST` client authentication method.
