Error Codes

If API calling fails, no result data is returned. You can locate the error cause according to the error code of each API. When the API 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 an error, contact customer service and provide the error code so that we can help you solve the problem as soon as possible.

The following is an example of an error response:

{
    "errors": [
        {
            "error_code": "DLV.1000",
            "error_msg": "Screen number exceed quota."
        }
    ]
}
