If an error occurs in API calling, no result will be returned. You can identify the error cause based on the error codes of each API.

If an error occurs in API calling (for example, HTTP status code 400 or 505 is returned), the response body contains the specific error code and information.

If you cannot locate the cause of an error, contact customer service and provide the error code, so that we can help you solve the problem as soon as possible.

Error Response Body Format

If an error occurs during API calling, an error code and the corresponding error message will be displayed. The following shows an error response body:

{
    "error_msg": "The format of message is error",
    "error_code": "AS.0001"
}

In the response body, error_code is an error code, and error_msg describes the error.

Error Code Description

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.
