After sellers create an Inbound Order successfully, the response from the Create Inbound Shipments API will tell whether the order can be sent in a single shipment to one WFS fulfillment center or needs to be split into multiple shipments to different fulfillment centers. To retrieve the Shipment level info, call the Get Inbound Shipments API, and to get what needs to be in a specific shipment and SKU level receipt situation, call the Get Inbound Shipment Items API.
