Apple's metadata API changes: no action needed with RevenueCat
Apple has notified developers that deprecated In-App Purchase and subscription metadata endpoints in the App Store Connect API will begin removal in early 2027. The new workflow attaches localizations and images to a version container that goes through App Review. RevenueCat says purchases, renewals, entitlements, webhooks and product sync are unaffected, and it will migrate its Product Editor and MCP tools by December 2026 with no SDK or configuration changes required.
What this means for indie developers：If you maintain your own App Store Connect API integration for IAP metadata, plan to migrate to the version-based endpoints before 2027; RevenueCat users can wait.
