The fulfillment object

In Shipup, a fulfillment represents a shipment of one or more items in an order. When an order has been completely fulfilled, it means that all the items that are included in the order have been sent to the customer.

In most cases, a merchant will make just one shipment per order, but sometimes the availability or size of items in the order requires a merchant to make more than one shipment. Each shipment should be treated as a separate fulfillment.

📘
On rare occasions, a fulfillment can later be split into multiple shipments. A fulfillment can thus have multiple tracker objects associated.
