Hi there, I’m Nikita, a backend developer at Qonversion helping developers optimize in-app purchases and subscription handling.

To manage in-app purchases seamlessly, you need to keep up with updates from App Store and Google Play, and today I'll walk you through the App Store Server API — a relatively recent update in StoreKit 2. We’ll dive deep into its key endpoints, explore how to integrate them into your backend, and discuss best practices for handling subscriptions, refunds, and analytics. I’ll also share some practical tips and examples, including Go-based implementations, to help you get the most out of this powerful API.
