capacitor-in-app-purchases

Create products in App Store Connect and Google Play Console, then install a purchases plugin such as @capawesome-team/capacitor-purchases or @revenuecat/purchases-capacitor. Implement fetching products, purchasing, finishing transactions, and restoring purchases, then run npx cap sync and test on physical devices.

Capawesome Purchases is lightweight with no third-party backend dependency, but you handle server-side receipt validation yourself and need a Capawesome Insiders license. RevenueCat provides managed receipt validation, entitlements, and analytics but requires a RevenueCat account.

Both Capawesome Purchases and RevenueCat require Capacitor 8 or later. Check the @capacitor/core version in your package.json before installing either plugin.

Android purchases fail if the app is sideloaded instead of installed from Google Play. Upload a signed build to the internal testing track, add tester emails under License Testing, and install via the opt-in link. Also verify products are in Active status.

Use Sandbox testing with a test account created in App Store Connect, signed in under Settings > App Store > Sandbox Account on a physical device. Alternatively, use StoreKit Testing in Xcode with a local configuration file, which works in the Simulator.

Unfinished transactions block future purchases on some platforms. Call getUnfinishedTransactions() at every app launch, deliver the content, and call finishTransaction() for each pending transaction.
