The Client Credentials Grant is one of the four grant types in the OAuth 2.0 specification. For more information about this grant type, see Client Credentials Grant.

Running the application

2. Enter the following details and click Authorize.

   Authorization Grant Type: Client Credentials
   Client ID: (the client id received at the application registration)
   Client Secret: (client secret received at the application registration)
   Access Token Endpoint: https://localhost:9443/oauth2/token

   OAuth 2.0 Token Introspection defines a protocol that allows authorized protected resources to query the authorization server to determine the set of metadata for a given token that was presented to them by an OAuth Client. This metadata includes whether or not the token is currently active (or if it has expired or otherwise been revoked), what rights of access the token carries (usually conveyed through OAuth 2.0 scopes), and the authorization context in which the token was granted (including who authorized the token and which client it was issued to). Token introspection allows a protected resource to query this information regardless of whether or not it is carried in the token itself, allowing this method to be used along with or independently of structured token values.

4. Now you should be able to see the access token information as seen below, as long as the provided access token is valid.
