Returns the inventory level for every SKU at every ship node.

• Each response contains up to 50 records (zero- or non-zero inventory).
• Use the nextCursor value from the last response to get the next page.

Call the endpoint repeatedly, passing the updated nextCursor each time—until the response omits nextCursor. The WFS Inventory API provides real-time inventory data for items fulfilled through Walmart Fulfillment Services (WFS). This API allows you to monitor stock availability, manage your catalog, item publishing, and lifecycle status. By querying for specific SKUs, you can access a wide range of inventory metrics, to ensure optimal stock management, streamline operations, and make informed decisions about WFS inventory.

Important: Effective May 15, 2026, the API will begin enforcing sequential behavior and no longer support parallel requests. Any request that submits a cursor out of order, reuses a cursor from a prior response, or runs multiple requests simultaneously within the same session will receive a 404 error. The API endpoint, data format, and response structure are not changing, only the enforcement of the documented sequential requirement.

Do I need to take action?

If you manage inventory through an approved Solution Provider, they are responsible for confirming their integration meets this requirement. If you have questions about how this change may affect your inventory management, please contact your approved Solution Provider directly.

If your integration already calls this API sequentially, one batch at a time before issuing the next request, then no changes are needed.

If your integration makes parallel or concurrent calls using the same cursor token, you will need to update before May 15 to avoid errors.
