The Walmart API Sandbox Beta for Marketplace Sellers is now available, which provides an environment to test Walmart APIs to ensure a successful integration and production launch. The Sandbox can be used for backend testing of APIs using mock responses. Sellers can use the Sandbox APIs to test out all changes in a safe and simulated environment. The API Sandbox can also be used to try out new features and provide feedback before changes are pushed to production.
