The GetUniquePackageLabels operation returns PDF
document data for printing unique shipping labels and carrier labels for an
inbound shipment. For information about extracting PDF document data,
see Extracting PDF Document Data.
Use this operation to get unique shipping labels for the packages in all types of inbound
shipments: Small Parcel, Less Than Truckload/Full Truckload (LTL/FTL), Amazon-partnered, or non-Amazon-partnered shipments. For
Amazon-partnered, Small Parcel shipments, this operation
returns carrier labels in addition to shipping labels.
The language of the address section of a shipping label is determined by the
ShipFromAddress value for the shipment, which was
specified with a previous call to the
CreateInboundShipmentPlan operation. The language of
the FC Prep instructions (if applicable) is determined by the marketplace of
the Amazon fulfillment center receiving the shipment.
