What happened?
The Walmart Marketplace Developer Portal showed a new version on September 17, 2026. However, the current public page does not provide specific change details. As a result, the page cannot reliably clarify which policies or fees are covered by the update, when the changes will take effect, or which sellers may be affected. The available information only confirms that the portal displays a new version; it does not establish any specific operating requirements or platform rule changes.
What does this mean for cross-border sellers?
The Walmart Marketplace Developer Portal only shows that a new version is available, while the public page has not disclosed specific changes. Sellers cannot yet confirm the policy, fee, effective date, or scope of impact. For now, prioritize record-keeping, monitoring, and current-state checks, and avoid making operational setting changes based on unknown information.
What should sellers do now?
