What happened?
TikTok Shop Partner Center published a summary of the September 2026 API updates on October 18, 2026, stating that three breaking changes require developer migration. The Cancel Order API will remove two buyer-responsible cancellation reasons; the Shipping Template widget will stop being available on October 31, 2026; and the single-video Analytics Details API will be retired by December 28, 2026, at the latest. Meanwhile, the new Shop Performance Score for the U.S. site went live on October 15, 2026, with the platform recalibrating metrics including product satisfaction and logistics fulfillment. Data returned by the legacy SPS API should be used for reference only, and systems should no longer treat the old score as the current seller performance. The changes apply to local and cross-border sellers in markets including the United States, the United Kingdom, the European Union, and Malaysia, and also affect ERP, order management, customer service, logistics plug-in, and data dashboard providers. Failure to migrate on time may result in failed order cancellations, unavailable shipping-template calls, interrupted analytics data, or incorrect seller-performance displays.
What does this mean for cross-border sellers?
This TikTok Shop update directly affects order cancellations, shipping templates, video analytics, and U.S. seller-performance displays. Local and cross-border sellers in the United States, the United Kingdom, the European Union, and Malaysia should take note. If ERP, order management, customer service, logistics plug-in, or data dashboard systems are not migrated, API failures, data interruptions, or incorrect performance displays may occur.
