Error Codes for Service Plane APIs

If an error occurs in API calling, no result is returned. Identify the cause of error based on the error codes of each API. If an error occurs in API calling, HTTP status code 4xx or 5xx is returned. The response body contains the specific error code and information. If you are unable to identify the cause of an error, contact technical personnel and provide the error code so that we can help you solve the problem as soon as possible.

If an error code starting with APIGW is returned after you call an API, rectify the fault by referring to the instructions provided in .
