An Inbound Shipment (also known as an Advance Shipping Notice, ASN, or Receiving Order) is a record of a shipment from a supplier (usually a vendor or factory) to a warehouse. Shipments are often associated with a Purchase Order, which represents the order that the warehouse sent to the supplier.

The Inbound Shipment contains information about the items being sent, including their individual inventory_item_ids. These IDs can be passed into the /wms-api/inventory/{inventory_item_id} endpoint for more details.
