This section outlines the steps required to register your application, complete reviews, and obtain approval to publish on the Walmart App Store. Follow these steps carefully to ensure a smooth submission and review process.

Overview of the process

The key steps involved in the Walmart App Store publishing workflow, include sandbox testing, app registration, credential management, review processes, and final app publication.

Obtain sandbox environment credentials: Start by integrating and testing your app using the Walmart API Sandbox environment with sandbox credentials.
Register your application: Register your application in the production environment to get production credentials.
Complete app registration details: Obtain your Client ID, Client Secret, and other necessary credentials for production use.
Submit your app for Walmart review and address feedback: Submit your app for Walmart’s review. Address any feedback or required changes provided by Walmart.
Publish to the Walmart App store: Once the application is approved, you can choose to publish your app in the App store.
Walmart marketing review: After your application is approved for publishing on the App Store, Walmart’s Marketing team will assist with creating and publishing the Walmart Solution Provider landing page to promote your app.

Step 1: Obtain sandbox environment credentials

The Walmart API Sandbox provides a dedicated environment for backend testing of Walmart APIs to ensure successful integration and a smooth production launch. The sandbox environment is intended for API testing only and not for testing on Walmart.com. It uses test-only elements and simulates real-time responses.

Use the Sandbox environment to integrate and validate your app before registering it for production.

Obtain your credentials from the Sandbox page to generate tokens and begin API integration testing. Refer to the Sandbox Environment documentation.
Use the values listed in Sandbox credentials (Client ID, Client secret, Refresh token, and WM Partner ID) to generate token as described in OAuth 2.0 Token Generation explained in Step 8, Fetching new access token using refresh token.
Make sure to use https://sandbox.walmartapis.com/v3/token  as the Request URI for generating the sandbox token.

Step 2: Register your application

As you work through the integration development, you can start the app registration process directly from the Solution Provider Center. App registration is required before you connect with the Walmart Partner Integration team for the initial onboarding kickoff call.

All required details must be finalized before Walmart can evaluate and approve the app. You must complete both Technical and Marketing sections to submit the app for review.

Choose an app listing type

As the first step in app creation, select the app listing type. This selection determines the remaining registration steps.

Solution provider (API access): Select this if your application requires API integration. You must provide a solution category, technical details for API access, general information about the app, and marketing details.
Agency (No API Access): Select this if you are an agency providing services without API integration. You must provide general information and marketing details.

For Solution Provider apps, select the appropriate App Category that determines where the app appears in the Walmart App Store (for example, shipping or inventory). If your app spans multiple areas, the Walmart Business and Integration team will advise on the best primary category based on the services offered.
