Overview

Amazon has released a refreshed version of its Warehousing and Distribution (AWD) API, identified as version 2024‑05‑09. The new endpoints become publicly reachable on June 21, delivering live inventory counts from AWD fulfillment sites and granular status updates for inbound shipments. Sellers and third‑party developers can now pull these data streams into their own systems, allowing faster stock‑level decisions and tighter logistics oversight.

Key Points

• Live inventory query — The API returns the exact on‑hand quantity for any SKU stored in an AWD center; for instance, a seller can see that 1,250 units of a winter coat are presently stocked at the Dallas hub.
• Inbound shipment milestones — Each request provides a chronological list of events for a shipment, such as “Loaded on carrier” on May 30 and “Arrived at AWD facility” on June 2 for a pallet containing 500 new units.
• Unified access role — Both marketplace sellers and external software partners use the same AWD role, meaning a third‑party inventory‑optimization platform can retrieve data for a seller without needing a separate credential set.
• June 21 activation — All qualified accounts will see the new endpoints on this date, giving sellers a clear deadline to migrate before the legacy version is retired.
• Standard REST design — Calls follow the existing SP‑API pattern, using JSON bodies and OAuth 2.0 tokens, so current SDKs require only minor adjustments to accommodate the new version.

How the New AWD API Works

1. Obtain an OAuth 2.0 token — The seller authenticates through the SP‑API login flow; for example, a vendor using the Java SDK invokes loginWithRefreshToken() to receive a token that remains valid for 60 minutes.
2. Request inventory data — With the token, the seller sends a GET request to /awd/inventory/v2024-05-09/sku/{sellerSku}. The response includes fields such as warehouseId, availableQuantity, and lastUpdated. A sample payload might return .
