After sending a shipment to Amazon's fulfillment network, you should call the
UpdateInboundShipment operation of the Inbound Shipment API
section. Include the ShipmentId that you used when you called the
CreateInboundShipment operation for that shipment. Also include
the ShipmentStatus request parameter with its value set to
SHIPPED. For more information about the Inbound Shipment API
section, see Fulfillment Inbound Shipment API. For code samples for calling the
UpdateInboundShipment operation, see the Client Library links on
the Amazon Marketplace Web Service (Amazon MWS) portal for your region.
