Fulfillment API

The outcome of a buyer's eBay checkout process is an order. Order payments are often processed immediately. However, in some cases such as cash on delivery (COD), order payments will be pending until other activities complete.

Note: The Fulfillment API covers only the transactions that have completed the checkout process. This includes both paid purchases and purchases that do not require upfront payment (such as COD). However, the API does not cover pending payment purchases that require upfront payment before shipment.

This API enables sellers to manage the completion of an order in accordance with the payment method and timing specified at checkout. The line items in the order are grouped into one or more packages. As the seller addresses, handles, and ships each package, you use the Fulfillment API to facilitate these activities. The set of specifications for this process is known as a fulfillment.

Business use cases

This section outlines the high-level use cases addressed by the Fulfillment API.

Discover orders that need to be fulfilled

Retrieve unfulfilled orders so you can create and process each order's shipping fulfillments. You can retrieve known orders or search for orders by creation date, modification date, or fulfillment status. See Discovering unfulfilled orders.

Package line items and define delivery parameters

Determine whether any line items in an order have not been assigned to a shipping fulfillment, or have been assigned to a shipping fulfillment but not fulfilled. Ensure that all line items have been included in one or more packages, and that each package is assigned to a shipping fulfillment. See Handling unfulfilled line items.

Monitor fulfillments to completion

Periodically retrieve and examine an order's shipping fulfillments to determine if they have been fulfilled. When all of the order's shipping fulfillments are complete, the order is fulfilled. See Managing fulfillments for an order.
