Authorization Response Error Codes

Error code

Description

Solution

invalid_request

The authorization request to Hub is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, or is otherwise malformed.

Check that all parameters are correct, that provided service_id exists, etc.

unauthorized_client

The client is not authorized to request an authorization code using this method: The redirect_URI of the service either is incorrect or not provided.

  1. Make sure the provided redirectUri is correct and properly registered as one of the service's redirect URIs.

  2. Make sure your service provides at least one redirect_uri in Hub.

unsupported_response_type

Hub does not support obtaining an authorization code using this method.

Try to change selected method of authorization.

invalid_scope

The scope for which authorization is requested, does not match any registered service.

Make sure that request is correct.

Error code

Description

Solution

invalid_request

The request is missing a required parameter, includes an unsupported parameter value (other than grant type), repeats a parameter, includes multiple credentials, utilizes more than one mechanism for authenticating the client, or is otherwise malformed.

Possible reasons: Authorization header in response is not of the Bearer type. Also, a parameter in the token request may be malformed or missing.

Please check the response header. Then check if the request is correct.

invalid_client

Client authentication failed. For example, the client is unknown, no client authentication included, or authentication method is unsupported.

Possible reasons:

  • No service with the provided clientServiceId was found.

  • Authorization header was either of invalid format or not passed at all.

invalid_grant

Possible reasons:

  • Refresh token was issued to another client service.

  • Refresh token is unknown.

  • Authorization code is unknown or is of invalid format.

  • The service secret is of invalid format.

  • Provided credentials of the service owner are invalid.

  • Requested scope does not match allowed by access token

unauthorized_client

Possible reasons: The service that requests authorization token is not verified.

unsupported_grant_type

Possible reasons: The authorization grant type is not supported by Hub.

invalid_scope

Possible reasons: The scope to which you are requiring access token does not match any registered service.

Please check the request.
