Error code
If a wrong API request is sent, or an error occurs during its processing, then the success/failure result is returned as an HTTP status code. The detailed message is then returned in the form of JSON/XML.
Response example
{
"responseError":{

"returnMessage":"Return message"
}
}
If the output format is XML
<responseError>
<returnCode>Return code</returnCode>
<returnMessage>Return message</returnMessage>
</responseError>
