What happened?
Walmart’s developer platform updated its order management API reference documentation on September 21, 2026, adding error examples related to Cross Border Trade and Out of Country shipment when using Ship with Walmart labels. The update primarily targets sellers and service providers operating Walmart Marketplace through APIs, ERP systems, WMS, third-party software, or self-built systems; it is not a front-end fee change for ordinary manual-operation sellers. Affected merchants include cross-border sellers shipping to the U.S. market from China, Canada, Japan, the United Kingdom, Mexico, and other locations, as well as technical sellers using Walmart labels, automated label generation, and order synchronization systems. Sellers need to check how their systems handle country codes, ship-from locations, destinations, carriers, label types, and customs-clearance information. Continuing to retry based on old error codes could cause label-creation failures, shipping delays, or unsynchronized order statuses. The actual impact depends on each seller’s API integration and fulfillment route.
What does this mean for cross-border sellers?
Walmart updated its order management API reference with new error examples for Ship with Walmart labels in cross-border trade and out-of-country shipment scenarios. Sellers using APIs, ERP, WMS, third-party software, or self-built systems should check country codes, fulfillment data, customs information, and legacy error-code retry logic to avoid label-creation failures, shipping delays, or status mismatches.
What should sellers do now?
- 1Have the technical team run a sandbox test or replay of Walmart cross-border orders, checking country codes, ship-from locations, destinations, carriers, label types, and customs information field by field. Produce a list of abnormal fields and their corresponding handling results.AI Customer Service
- 2Review legacy error-code retry rules in ERP, WMS, and self-built systems. Test Cross Border Trade and Out of Country shipment scenarios separately for Ship with Walmart labels, and complete a correction record that prevents duplicate retries.
