# Choosing a StoreKit API for In-App Purchases Use the latest API to support In-App Purchases in new or existing apps, or the original API to support In-App Purchases in earlier operating systems. ## Discussion The StoreKit framework provides two APIs to implement a store in your app and offer in-app purchases: - [In-App Purchase](/documentation/StoreKit/in-app-purchase) is a Swift-based API that provides App Store-signed transactions in JSON Web Signature (JWS) format, available starting in iOS 15, macOS 12, tvOS 15, watchOS 8, and visionOS 1. - [Original API for In-App Purchase](/documentation/StoreKit/original-api-for-in-app-purchase) provides transaction information using App Store receipts, available starting in iOS 3, macOS 10.7, tvOS 9, watchOS 6.2, and visionOS 1. > Note: > The is deprecated. If your app has a minimum required operating system that the [In-App Purchase](/documentation/StoreKit/in-app-purchase) API supports, use this API to take advantage of Swift concurrency and simplified in-app purchase workflows. Use this API for visionOS apps that use multiple scenes. Use the [Original API for In-App Purchase](/documentation/StoreKit/original-api-for-in-app-purchase) to maintain and update app versions that have a minimum required operating system of the following versions: macOS 11 or earlier, iOS 14 or earlier, iPadOS 14 or earlier, tvOS 14 or earlier, or watchOS 7 or earlier. An app can use both the [In-App Purchase](/documentation/StoreKit/in-app-purchase) API and the [Original API for In-App Purchase](/documentation/StoreKit/original-api-for-in-app-purchase) if the app runs in iOS 15, macOS 12, tvOS 15, watchOS 8, and visionOS 1 or later. However, only the [In-App Purchase](/documentation/StoreKit/in-app-purchase) API supports multi-scene apps for visionOS. Both APIs provide access to your data in the App Store, such as your configured in-app purchases and transaction information for your customers. In-app purchases that users make using either API are fully available to both APIs. ### Use the In-App Purchase API to access new features The following features are available only with the Swift-based [In-App Purchase](/documentation/StoreKit/in-app-purchase) APIs: - [StoreKit views](/documentation/StoreKit/storekit-views), which provide the UI to build a store in your app - Refund request sheets, such as [`beginRefundRequest(for:in:)`](/documentation/StoreKit/Transaction/beginRefundRequest(for:in:)-65tph), that enable customers to request refunds - Information about a subscription’s renewal status, such as auto-renew preferences. For more information, see [`Product.SubscriptionInfo.Status`](/documentation/StoreKit/Product/SubscriptionInfo/Status-swift.struct). - Information about available promotional offers and a subscriber’s eligibility for an introductory offer. For more information, see [`Product.SubscriptionInfo`](/documentation/StoreKit/Product/SubscriptionInfo). - Deferring or suppressing Billing Issue messages that the system displays. For more information, see [`Message`](/documentation/StoreKit/Message). - Presenting the App Store sheet for managing subscriptions. For more information, see [`showManageSubscriptions(in:subscriptionGroupID:)`](/documentation/StoreKit/AppStore/showManageSubscriptions(in:subscriptionGroupID:)). - Transaction information in JSON Web Signature (JWS) format. For more information, see [`Transaction`](/documentation/StoreKit/Transaction). ### Use the Original API to support certain features You might need to use the [Original API for In-App Purchase](/documentation/StoreKit/original-api-for-in-app-purchase) for the following features, if your app supports them: - Promoting in-app purchases in apps that run in iOS 11 through 16.3. For more informaton, see [Promoting In-App Purchases](/documentation/StoreKit/promoting-in-app-purchases). For information about this feature in iOS 16.4, see [Supporting promoted In-App Purchases in your app](/documentation/StoreKit/supporting-promoted-in-app-purchases-in-your-app). - The Volume Purchase Program (VPP).
