Marketplace API Sandbox

The target audience is Marketplace Sellers who are onboarded to sell items on Walmart.com and are integrating their apps with new or existing APIs.

The Marketplace API Sandbox provides a test environment for sellers to test APIs before they push to production to ensure a successful integration.

When you create your API keys in the developer portal, you can also create sandbox API keys.

Marketplace APIs will have new Sandbox-only URLs alongside the standard production URLs. The samples, error codes and reports will be the same as the production APIs.

When you log into the Walmart Developer Portal, it takes you to the API Keys for Production and Sandbox. For more details, see Authorization.

Yes, make sure you are using the Item Specification version 3.

The benefits to using the Sandbox include:

• Access simulation APIs that you can call from your applications, in realtime, to test the integration process.
• Perform basic validations on the feeds, payloads, etc. to lessen data quality issues on production.
• Deploy with confidence as all test failures occur in a safe environment.
• Test in parallel with development without hindering project timelines.
• Try out new features and provide feedback before changes are pushed to production.

The scope of the sandbox environment includes:

• Marketplace APIs
• API request and response validation
• Spec validation
• Mock responses
• Throttling limits
• Error codes
• Delegated Access

• The items will not be seen on Walmart.com.
• Sandbox environment is NOT a full stack staging environment so partners will not be able to do end-to-end testing.
• Responses are based on mock data.
