All errors have their own code, allowing you to perform some automatic activity in the event of receiving one. For example, entering in a non-existent consignment code where a valid one is required will result in a particular fault. All error codes start with "E" and are followed by five decimal digits (padded with zeros).

In addition to the error codes, we also have Incident Report Codes. A new one is assigned each time a fault occurs, allowing us to track it through the system. All report codes start with "R" and are followed by five decimal digits (padded with zeros).

For connectivity issues, we recommend you implement a retry process to submit your requests again at a later time.
