The API authorization can be done using a Session Key, REST API Key, or Open ID Connect (OIDC) authorization. To use REST API Key as authorization, you need to create a REST API Key. For more information, see [Using REST API Key](docId\:UaQTDeGHj3Ebw29Q0goP8).

If OIDC is enabled in ConfigDB on the tenant used to log-in, JWT Bearer Token is generated, else, Session Key is generated.
