Get started as a Solution Provider

Walmart Marketplace isn’t only for sellers. Companies can be approved Solution Providers who develop software that could improve sellers’ eCommerce workflows and contribute to their success.

Register to be an approved Solution Provider

1. Apply to become a Walmart Solution Provider by completing this submission form. The entire approval and application publication process may take between three to five weeks.
2. Walmart will send an approval email after review to connect with the Walmart Partnerships team for consultation.
3. You will then be invited to register on the Solution Provider Center to get Sandbox access for Development.
4. Implement OAuth 2.0 authorization.
5. After integration development, register the application for listing on the Seller Center App Store. Submit your application for verification.
6. The verification process with Walmart ensures that the core seller experiences work as intended. You will be requested to demo your application to confirm application functionality. Walmart needs to approve your application before you can publish it for Sellers on the Seller Center App Store.
7. After approval, your application you can published to be listed on the Marketplace App Store website as an approved Solution provider

Implement OAuth2.0

OAuth 2.0 is the industry standard for token-based authentication and API authorizations. It adds an extra layer of security, making the process more secure for users. OAuth 2.0 makes the process seamless and more secure than manual authentication methods.

Why you should implement OAuth 2.0

When your application uses OAuth 2.0, the onboarding process for sellers is simplified. Sellers can select Connect from your Seller Center App Store listing and sign in to authorize your application for access to their eCommerce information.

The Delegated Access method is no longer supported. Moving forward, all approved Solution Providers are expected to use OAuth 2.0.
