# App Store Connect API 4.5 release notes Update your server-side code to use new features, and test your code against API changes. ## Discussion App Store Connect API version 4.5 provides resources that enable you to automate actions you take in App Store Connect. ## Added - Evaluate your app’s performance before you release an update. Use [`Get the performance overview for an app`](/documentation/AppStoreConnectAPI/GET-v1-apps-_id_-performanceOverviews) to read the aggregated performance overview data for an app, including the metrics Xcode surfaces in its performance reports. - Offer subscriptions to organizations. The `marketSettings` and `multiSeatStatus` attributes on [`Subscription`](/documentation/AppStoreConnectAPI/Subscription) indicate the markets where a subscription is available — the App Store, Apple School Manager, or Apple Business Manager — and whether the subscription supports multiple seats. - Moderate Game Center leaderboard scores and the players who submit them. Use [`List Score Moderations for a Leaderboard`](/documentation/AppStoreConnectAPI/GET-v2-gameCenterLeaderboards-_id_-gameCenterScoreModerations) to review the scores submitted to a leaderboard and [`Modify a Game Center Score Moderation`](/documentation/AppStoreConnectAPI/PATCH-v1-gameCenterScoreModerations-_id_) to block a score. Read the players a game blocks with [`List Blocked Players`](/documentation/AppStoreConnectAPI/GET-v1-gameCenterDetails-_id_-blockedPlayers), and block or unblock an individual player with [`Modify a Game Center Detail Player`](/documentation/AppStoreConnectAPI/PATCH-v1-gameCenterDetailPlayers-_id_). - Align your app with Korea’s age-rating classifications. Use the `ALL` and `TWELVE_PLUS` values in the `koreaAgeRatingOverride` attribute of [`AgeRatingDeclaration`](/documentation/AppStoreConnectAPI/AgeRatingDeclaration) to set the most accurate age-rating classification. ## Deprecated - The `territories` relationship on app tags is now deprecated, along with the [`List Territories for an App Tag`](/documentation/AppStoreConnectAPI/GET-v1-appTags-_id_-territories) and [`List territory IDs for an app tag`](/documentation/AppStoreConnectAPI/GET-v1-appTags-_id_-relationships-territories) endpoints. On [`List App Tags`](/documentation/AppStoreConnectAPI/GET-v1-apps-_id_-appTags), the `include`, `fields[appTags]`, `fields[territories]`, and `limit[territories]` parameters no longer accept `territories` values. --- Copyright © 2026 Apple Inc.
