AuthZ Error Codes

HTTP STATUS HTTP CODE CAUSE/RESOLUTION

FORBIDDEN

403

The 403 (Forbidden) HTTP Status code indicates that this project does not have permission to access the requested resource.

Check for the following:

  • You are using a project and the credential for the project which includes the API being accessed.
  • Create a project and receive sandbox credentials for the API’s being called.
  • Add the API being called (if not already included) to the project with credentials that are being used.
