          This API endpoint allows you to authorize another user to access your model in a read or write capacity.
          Before calling authorize, you must first make sure your model has been registered.
  
          Inputs:
          email - String: The email of the user you would like to share access with.
          permission_type (optional) - String: One of ['read', 'write'].  Users with read permissions can only call `predict`.
            Users with `write` permissions can add new input examples and train models.
          api_key (optional) - String: Your API key, required only if the key has not been declared
            elsewhere. This allows the API to recognize a request as yours and automatically route it
            to the appropriate destination.
          cloud (optional) - String: Your private cloud domain, required only if the key has not been declared
            elsewhere. This allows the API to recognize a request as yours and automatically route it
            to the appropriate destination.
