As a user I scan my shipping label to bring up the order details in our WMS. I then scan each item of the order to confirm the PACK process. However I need the barcode on the Sendle label to match the tracking number we have recieved from Starshipit in the API when we preprinted the labels. Currently Sendles tracking number is not related to the barcode on the label. The barcode actually belongs to one of their carrers.
