IG 2023.11


Supports client authentication with the method client_secret_post. Clients that have received a client_secret value from the Authorization Server authenticate by including the client credentials in the request body, as in the following example:

POST /oauth2/token HTTP/1.1
Host: as.example.com
Content-Type: application/x-www-form-urlencoded


Use this filter with an endpoint Handler that requires client_secret_post authentication. For example, endpointHandler in the OAuth2TokenExchangeFilter or ClientCredentialsOAuth2ClientFilter.
