How do I integrate my application with the platform?
Integrate Your Application with Item Management APIs

Use the API Explorer page to test the APIs. Integrate your application with the item management platform by calling the item management APIs.
For setting up an item, use the provided XSDs to build an XML payload to ingest item feeds.

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

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 realtime.

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 ability to monitor API behavior before moving to production.
