New DSV Inventory and Lag Time Management APIs

April 18, 2023

Walmart is releasing a new API for Drop Ship Vendors (DSV) to manage their item inventory and order lag time more efficiently and accurately. The primary identifier has been changed to the global trade item number (GTIN) to enhance accuracy. Additionally, a new Read API and an updated Post APIs have been created to help reduce the number of required system calls.

Inventory API

  1. Walmart has changed the primary identifier for inventory updates from the stock keeping unit (SKU) to global trade item number (GTIN).
    • POST requests: GTIN is the only primary identifier accepted for new released versions.
    • GET requests: Both SKU and GTIN are supported to read inventory levels.
  2. POST Update Bulk Item/Node schema update: Walmart has created a new v2.X version. The new version has a flattened request structure to help improve processing time.
  3. New GET Single Item/Multiple Nodes read request: Enables users to view inventory levels on a single item across multiple ship nodes. This includes two new attributes, in addition to on-hand inventory:
    • Reserved inventory for customer orders
    • Inventory amount available to sell

Lag Time API

For lag time, the primary identifier has been changed to GTIN.

  • POST request: GTIN is the only primary identifier accepted for new released versions.
  • GET requests: Both SKU and GTIN will continue to be supported.

Only business-approved suppliers will have access or permissions to access and update Lag Time requests. If suppliers do not have access to the Lag Time API, they can request access from the Walmart Drop Ship Vending (DSV) Business Operations team.
