App Store Server API is one of 199 APIs that [iOS](https://apis.io/providers/ios/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include In-App Purchases, Subscription, Receipts, Refunds, and StoreKit. The published artifact set on APIs.io includes API documentation and an API reference.

The App Store Server API is the server-to-server REST API for managing App Store transactions — looking up transaction history, fetching all subscription statuses for a customer, requesting test notifications, and issuing refunds. It pairs with StoreKit on the device and with App Store Server Notifications v2 for asynchronous state changes. Authentication is JWT (ES256) signed with a key created in App Store Connect; payloads and responses are JWS-signed JSON.
