In-depth guide

Steps

1. After an order is created, retrieve its fulfillment orders by calling GET /admin/api/2024-01/orders/{order_id}/fulfillment_orders.json; each fulfillment order groups line items by location and fulfillment service
2. Identify the fulfillment order ID(s) that belong to your fulfillment service by inspecting the assigned_location and fulfillment_service fields
3. Request fulfillment by POSTing to /admin/api/2024-01/fulfillment_orders/{fulfillment_order_id}/fulfillments.json with line item quantities and optionally tracking information
4. If the fulfillment service needs to accept the request first, respond to the fulfillment_orders/fulfillment_request webhook and call the accept endpoint at /admin/api/2024-01/fulfillment_orders/{id}/fulfillment_request/accept.json
5. Update tracking after shipping by POSTing tracking information to the fulfillment using the fulfillment update endpoint, setting tracking_number, tracking_url, and tracking_company
6. Mark the fulfillment complete or trigger partial fulfillment by specifying only the line item IDs and quantities that were shipped in the fulfillment creation payload
