The Swift server library for the App Store Server API and App Store Server Notifications. Also available in Java, Python, and Node.js.
Add the following dependency
.package(url: "https://github.com/apple/app-store-server-library-swift.git", .upToNextMinor(from: "2.2.0")),To use the App Store Server API or create promotional offer signatures, a signing key downloaded from App Store Connect is required. To obtain this key, you must have the Admin role. Go to Users and Access > Integrations > In-App Purchase. Here you can create and manage keys, as well as find your issuer ID. When using a key, you'll need the key ID and issuer ID as well.
Download and store the root certificates found in the Apple Root Certificates section of the Apple PKI site. Provide these certificates as an array to a SignedDataVerifier to allow verifying the signed data comes from Apple.
