Air Duplicate Shipments

When creating an air shipment, the system checks for duplicates to avoid creating multiple entries;

If a shipment with the same reference and AWB number already exists, a new shipment will not be created and no cost will be applied.
If you don't provide a reference field on your request, the system will only check with the awb number.

If you are using the API, in such cases the system will return a (409 - ALREADY_EXISTS) response, including the details of the existing shipment.

TIP 💡 If you want to add a follower or tag to the existing shipment, you must make new request(s) to related endpoints using the existing shipment's id.
