Error Code

No data is returned if an API fails to be called. You can locate the cause of error according to the error code of each API. When the calling fails, HTTP status code 4xx or 5xx is returned. The returned message body contains the specific error code and error information. If you fail to locate the cause of error, contact the database customer service and technical support 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 API gateway error codes.
