The token introspect endpoint is used for determining the active state and the meta-information of an OAuth 2.0 token. Only an authorized protected resource can query an OAuth 2.0 authorization server for token introspection.
This endpoint returns a JSON response, which is implemented based on RFC 7662.
Endpoint URL: https://<Identity Server URL: Port Number>/nidp/oauth/v1/nam/introspect
Request method: POST
You must use any one of the following methods to authenticate a request:
Authorization header with any of the following values:
For client_secret_basic: Basic Base64Encode of(<client_id>:<client_secret>)
For bearer: Bearer <access_token_generated_using_client_credential_flow>
client_secret_post (using client_id and client_secret in request body parameters)
The following is the priority list in which token introspect considers these methods:
client_secret_basic
bearer
client_secret_post
If you send a request to token introspect endpoint with client_secret_post (client_id and client_secret in request body) and client_secret_basic (basic authorization header), the endpoint validates the request based on the credentials that are provided through client_secret_basic.
If values in client_secret_basic are invalid, the response displays 401 exception. The endpoint does not consider client_id and client_secret in client_secret_post when client_secret_basic is available in the request.
NOTE:If you provide more than one method for authentication, the introspect endpoint returns the response based on the priority.
