Inventory API Overview

Inventory Management

Walmart's Inventory Management API provides drop ship vending (DSV) suppliers with mechanisms to update and view current item inventory levels at each ship node, also known as fulfillment centers. Suppliers assign each item they fulfill drop ship vending (DSV) through one or more ship nodes. Suppliers must accurately maintain the item's inventory level at each ship node to ensure availability for customer orders.

There are several requests to manage inventory:
