What are pre-requisites to implement in-app purchases?

🛠️ Here are some key pre-requisites required before implementing in-app purchases on iOS and Android.

1. Developer Account & App Setup

  • iOS: Enroll in the Apple Developer Program & set up App Store Connect.
  • Android: Register for a Google Play Developer Account & enable Google Play Billing.

2. App Permissions & Store Configuration

  • Enable in-app purchases in the App Store Connect (iOS) & Google Play Console (Android).
  • Set up App ID, bundle identifier, and billing permissions in the app's manifest.

3. SDK & API Requirements

  • iOS: Install StoreKit Framework for purchase handling.
  • Android: Integrate Google Play Billing Library for transactions.
  • Cross-Platform: Use plugins like Flutter’s in_app_purchase, React Native IAP, or Unity IAP.

4. In-App Product Setup

  • Define product types (consumables, non-consumables, and subscriptions) in App Store Connect & Google Play Console.
  • Configure pricing, localization, and regional availability.

5. Security & Testing Readiness

  • Enable Sandbox Testing (iOS) & License Testing (Android).
  • Implement secure API calls & transaction validation to prevent fraud.
  • Ensure compliance with PCI-DSS & local payment security regulations.

6. (Optional but Recommended) Backend Setup

  • Use App Store Server API (iOS) & Google Play Developer API (Android) for server-side receipt validation.
  • Set up subscription management (renewals, cancellations, refunds).

These steps ensure your app is fully prepared to implement in-app purchases.
