Starting January 27, 2026, we will begin the external release of the planned tables. Over the next three days (through January 30, 2026), all tables will be batch-revamped to the new Upstream Tables. During this activity, some feeds may temporarily send additional I/U/D (Insert/Update/Delete) records: Extra Inserts: Compare against the primary keys (PKs) and ignore any records you already have. Extra Updates (without prior inserts): If the PK combination doesn’t exist in your system, insert the record. Extra Deletes: If the PK combination doesn’t exist in your system, ignore the delete.
The Store Inventory APIs provide suppliers with near real-time visibility of available inventory at our Walmart stores. Suppliers can use this endpoint to request inventory status information for a single item. For multiple items, please use the Multi Item Inventory endpoint.
