The Oracle Communications Session Delivery Manager returns standard HTTP error codes.

400 Bad Request

The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

401 Unauthorized

The request has not been applied because it lacks valid authentication credentials for the target resource.

403 Forbidden
