App Store Connect API 4.4 release notes

Update your server-side code to use new features, and test your code against API changes.

Overview

App Store Connect API version 4.4 provides resources that enable you to automate actions you take in App Store Connect.

Use Subscription plan availability to configure monthly subscriptions with a 12-month commitment.
Added STORAGE to MetricCategory. Track your app’s storage footprint over time to catch regressions in data usage and binary size.
Added the ANIMATION MetricCategory, which displays information about the hitch rate of your app over time. The hitch rate tracks animation interruptions across all animated interactions in your app, including scrolling, transitions, and other continuous motion. To learn more, see Understanding user interface responsiveness.
Metric goals are now available for Battery Usage, Disk Writes, Hang Rate, Hitches, Memory, and Storage metrics, so you can prioritize performance engineering across more areas. Similar-app goals now cover Hang Rate, On-screen Battery Usage, Disk Writes, and Storage. Launch Time similar-app goals are more accurate, establishing new baselines. To learn more, see MetricCategory.
Added a ZERO_ZERO value to AppStoreAgeRating, representing Vietnam’s 00+ age-rating classification.

Background Assets now supports multiple locales, so your app can deliver only the assets that match a customer’s locale preference. Use List all background assets for an app with the filter[versions.locale] parameter to read the uploaded locales.

The user role permission ACCESS_TO_REPORTS for App Store Connect API is deprecated. See UserRole for available alternatives.
The Subscription availability resource is deprecated. Use Subscription plan availability instead.
The goalKeys property of xcodeMetrics.ProductData.MetricCategories.Metrics is deprecated.

Removed the GET /v1/appStoreVersions/{id}/relationships/ageRatingDeclaration and GET /v1/appStoreVersions/{id}/ageRatingDeclaration endpoints. Use Read the age-rating declaration instead.
