Problem with CompleteSale and half.com shipping notes field
The simple task of editing the shipping note, a unique field to
half.com orders, proves impossible due to an API error in CompleteSale incorrectly associating it with the "ShipmentTrackingDetails" container. The "Notes" element is NOT part of that container. The following simple request fails with the bizarre error 21916964 - Tracking number(s) already exists. MY_AUTH_TOKEN This is my shipping note. MY_ITEM_ID MY_TRANS_ID Halfen_USHigh For
Half.com, the seller shipment notes can be updated/edited at anytime AFTER the tracking number has been added to the order regardless of the orderStatus being marked "Shipped" or not. The CompleteSale API is not reflecting this expected behavior from the
half.com Web UI. For reference, the "Shipped" boolean "/Shipped" can be successfully marked off and on without receiving any 2916964 errors, which is as expected and mirrors the
half.com Web UI behavior correctly. The shipment notes update(s) should respond similarly.
