Great question! Here's the current situation regarding Apple In-App Purchases / StoreKit in Base44: StoreKit / Apple In-App Purchases — Not Yet Supported Base44 mobile apps currently do not support StoreKit or Google Play Billing for in-app purchases of digital goods. This is an important limitation to be aware of, especially for App Store submissions. From the documentation: Digital goods (e.g., subscriptions or in-app features): Do not use Stripe for payments inside your mobile app. Apple and Google require their own billing systems for digital content. If your app uses Stripe for digital content, your app will be rejected. "We are working on a built-in integration for StoreKit and Google Play Billing to handle digital purchases and keep your app compliant." What This Means for Your App ✅ Physical goods & services — Stripe is allowed in the App Store for physical products/services ❌ Digital goods (subscriptions, in-app features, virtual items) — These require StoreKit (iOS) / Google Play Billing (Android), which Base44 doesn't support yet If your app sells digital content via Stripe, it will likely be rejected by Apple during review What You Can Do Now Vote/track the feature — You can upvote this on the Base44 feedback board to help prioritize it Design around physical services — If your app deals with real-world services (bookings, physical products), Stripe works fine Wait for the StoreKit integration — Base44 has acknowledged they're working on it Is your Baukey app planning to sell digital content/subscriptions, or does it deal with physical goods/services? That would help clarify whether this limitation affects you directly!
