Choose an Inventory API

The Walmart Marketplace Inventory API has two main ways to manage your inventory:

• Retrieve inventory data
• Update inventory data

Retrieve inventory data

View current inventory levels for standard seller-fulfilled items by getting the inventory count for an item.

Sellers often begin by retrieving their inventory to get an accurate view of stock levels before any adjustments.

Update inventory data

Modify existing inventory quantities. You can update single SKUs on demand or run bulk updates for many SKUs in one file.

After reviewing current inventory, sellers often update stock levels to reflect recent sales, shipments, or adjustments.
