# Inbound Shipments

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_id`s. These IDs can be passed into the [`/wms-api/inventory/{inventory_item_id}`](/api-reference/wms-api/inventory/get-item) endpoint for more details.

### Inbound Shipment Statuses (in order of lifecycle)

| Status       | Definition                                                                                                                |
| :----------- | :------------------------------------------------------------------------------------------------------------------------ |
| `open`       | Shipment record has been created and items are not yet in the warehouse.                                                  |
| `in-transit` | Items are on their way to the warehouse.                                                                                  |
| `receiving`  | The warehouse has begun the receiving process for the shipment.                                                           |
| `received`   | Items have been received in the warehouse.                                                                                |
| `cancelled`  | Shipment has been cancelled by either the warehouse or the customer.                                                      |
| `other`      | Status of the shipment can't be determined. Often due to a custom status being used. See raw\_status field for more info. |
