Developers Program
  • Important Update: eBay's API integrations will be modified to address data handling requirements for select developers. Usernames will be replaced with immutable user IDs, and financial data will be protected for certain users. Learn more here.
  • Action Required: From early May, API users must include standardized condition details when creating or updating listings in certain coins category. Update your integration to stay compliant. Learn more here.
  • Size Standardization Update: Apparel & Footwear listings with non-standard, missing, or incomplete size information may be blocked or hidden starting August 2026. Normalization begins in June. Learn more here.
  • Action Required: A new Right of Withdrawal (ROW) return reason will be added to the getReturnDetails API for eligible EU returns. Update your integration so it can safely handle new/unknown return reason enum values without errors. Learn more here.
