To implement in-app purchases, you can leverage several tools and APIs provided by Apple. Here's a brief overview of the process and some resources from WWDC sessions that can help you:
-
StoreKit: This is the primary framework for implementing in-app purchases within your app. It allows you to handle transactions, manage product information, and more. You can learn about the latest updates in StoreKit from the session What’s new in StoreKit and In-App Purchase.
-
App Store Server APIs: These APIs allow your server to interact with the App Store to manage transactions, handle refunds, and more. The session Explore App Store server APIs for In-App Purchase provides insights into the purchase lifecycle and how to deliver content effectively.
-
Signing Requests: To ensure secure transactions, you can sign your in-app purchase requests using the App Store Server Library. This is covered in the session Dive into App Store server APIs for In-App Purchase.
-
Testing: You can test your in-app purchase flows using Xcode. The session What’s new in StoreKit and In-App Purchase discusses how to test purchase intents and other features in Xcode.
-
Promotional Offers: You can create promotional offers for subscriptions using the new JWS-based Subscription Promotion Offer modifier. This is detailed in the session What’s new in StoreKit and In-App Purchase.
These resources should provide a comprehensive guide to implementing and managing in-app purchases in your app.
