Keycloak REST API with Postman
Demonstrate how to use Keycloak's admin REST API with a postman client application.
For invoking a REST endpoint, client application should obtain an access token. After that the access token should be added to the authorization header of each REST API call as a bearer token.
OAuth 2.0 protocol is used to obtain access token.
