Body parameters

Important

Body parameters are case-sensitive.

If you experience an InvalidRequestBody or MissingRequiredParameter error, it might be caused by a typo. Review the API documentation and check that the submitted parameters match the relevant example.

Tracking ID

Each error response contains a unique ID parameter for tracking. The property name of this parameter is target. When contacting us about an error, attaching this ID will help us find the root cause of the problem.
