post https://api.helloextend.com/line-items/shipments/delete
This endpoint allows shipment information to be deleted from an order line item using the Extend Line Item ID or Line Item Transaction ID (the merchant’s unique identifier for the order line item).
Shipment information may need to be deleted from an order line item if it was created in error or another scenario where updating the shipment will not address the shipment information data that was originally provided.
