When performing a shipment SKULabs communicates directly with the shipping carrier about the details of the shipment, and in return, the carrier provides the shipping label. SKULabs has limited design control because the generated label is actually produced within the carrier system.
However, there are options for replacing variables within the shipping label to display per your needs, which are found in the Reference Field Templates area of SKULabs.
ORDER_NUMBER - Order number
NOTES - Order notes
STORE_NAME - Store name
USERNAME - Username from eBay and other channels.
EXTERNAL_ORDER_ID - Order ID from external source

LISTING_IDS - List of listing IDs and quantities. e.g. 5x 612940b74b
LINE_SKUS - List of listing SKU and quantities. e.g. 5x ABC-245-RD
BATCH_NUMBER - The batch number used to stage the order for shipment.
BIN_NUMBER - In batches, the batch bin number is used to stage the order for shipment.
