What happened?
Walmart’s official partner page states that the legacy Walmart Partner Portal was fully retired on September 30, 2026. Starting September 2, the platform had redirected legacy links to the new unified OpenTTD portal. The change primarily affects sellers and technology service providers using Walmart APIs, product catalog interfaces, advertising data interfaces, inventory synchronization, order management, and third-party ERP or ISV tools. According to the official notice, developer documentation from the legacy portal will be moved to OpenTTD. Apps previously created or managed through the Partner Portal must be accessed through App Management or direct app links. Sellers that still rely on old bookmarks, legacy API documentation, or third-party authorization processes may encounter unavailable interface documentation, missing apps, renewed permission authentication, or interrupted data synchronization. The announcement did not introduce new commissions or transaction fees, but it directly affects the technical infrastructure used for multichannel operations.
What does this mean for cross-border sellers?
Walmart has retired the legacy Partner Portal. Sellers using APIs, webhooks, inventory pushes, order pulls, or third-party ERP/ISV tools may encounter unavailable documentation, app access issues, or renewed authorization requirements. Migrate to OpenTTD and App Management promptly to avoid interruptions to multichannel data synchronization.
