Try Client Credentials Grant

Running the application:

1. Visit the URL http://localhost:8080/playground2/oauth2.jsp to start 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)
   Authorize Endpoint: https://localhost:9443/oauth2/authorize

   If you have configured the service provider in a tenant, you have to add the tenant domain as a query parameter to the access token endpoint.

   If the tenant domain is wso2.com, access token endpoint will be as follows.

   Access Token Endpoint: https://localhost:9443/oauth2/token?tenantDomain=wso2.com

    

   

3. At this point the application receives the Access Token.
