How can I test out my APIs? Do you have a test environment?

For Marketplace:

Yes! Use Walmart API Sandbox

The Walmart API Sandbox provides an environment to test Walmart APIs to ensure a successful integration and production launch. The Sandbox is only for backend testing of APIs and there is not an option to view or test on Walmart.com. This environment uses test-only elements and simulated responses (based on mock data) and calls to applications in real-time.

All URLs, Endpoints, Users, Items, Orders, and currency/funds within the Sandbox are for testing purposes only. This environment provides production simulation, debugging, reports, and the ability to monitor API behavior before moving to production.

For Walmart 1P:

Yes! We have launched the Walmart API Sandbox for 1P Suppliers.

The Walmart API Sandbox provides an environment to test Walmart APIs to ensure a successful integration and production launch. The Sandbox is only for backend testing of APIs and there is not an option to view or test on Walmart.com. This environment uses test-only elements and simulated responses (based on mock data) and calls to applications in real-time.

Note: Only selected API’s, Feed Types, and Reports are currently supported in the Sandbox. See the detailed list here.
