Overview

Amazon’s Selling Partner API (SP‑API) has added native tracking number support to the Fulfillment Outbound API for Multi‑Channel Fulfillment (MCF) orders. As of the latest release, the getFulfillmentOrder call now returns an amazonTrackingNumber field, allowing sellers to retrieve MCF tracking data programmatically without extra lookups. This change shortens the time between shipment creation and customer notification, a critical factor for sellers who fulfill orders from external platforms such as Shopify or WooCommerce.

Key Points

• New amazonTrackingNumber field — The getFulfillmentOrder response now includes a tracking identifier for every MCF shipment that has been assigned a number.
• Two‑step tracking flow — Sellers can feed the returned tracking number into the getTracking endpoint to obtain carrier details, event history, and estimated delivery dates.
• MCF‑focused visibility — The enhancement mirrors the tracking experience already available for Amazon marketplace orders, eliminating the previous gap for off‑Amazon sales.
• Unified response payload — Tracking data is embedded directly within the fulfillment order object, keeping the API schema unchanged and reducing integration overhead.
• Real‑time assignment — Tracking numbers appear as soon as Amazon’s fulfillment network generates them, enabling faster automated communications.

How the Update Works

1. Request fulfillment order — Call getFulfillmentOrder with the specific fulfillment order ID.

   • Example: A seller submits GET /fba/outbound/v0/fulfillmentOrders/1234567890 and receives a JSON payload that now contains "amazonTrackingNumber": "TBA123456789US".

2. Extract tracking number — Parse the response to capture the amazonTrackingNumber value.
