Base44 In-App Purchases: Apple IAP Without a Rebuild

The Limits of Base44 for Mobile Monetization

You built a working app in Base44. Now you want to charge for it on iOS — and you've hit the Apple wall. Apple requires native StoreKit for any digital purchase. Stripe is not allowed. Web-only paywalls get rejected at review. And building StoreKit yourself means rewriting your Base44 app as a native Swift project — defeating the whole point of building in Base44. Wanilla is the App Store launch and growth partner for Base44 founders. Wanilla builds your product into an iOS app with native features and prepares an honest App Store submission. You keep editing in Base44. We handle the iOS side.

How to Implement In-App Purchases in Base44 using Wanilla

Wanilla adds native in-app purchase capabilities to your Base44 app by embedding StoreKit and Google Billing Library into the native iOS app. Define your products in App Store Connect, map them in Wanilla, and trigger purchases from your Base44 app with a simple JavaScript call. Receipts are validated server-side and purchase events are sent to your backend.

How Wanilla builds a native app around your Base44 product with In-App Purchases

Code Integration Example

The in-app purchase integration supports all product types: consumables for credit-based systems, non-consumables for permanent unlocks, and auto-renewable subscriptions for recurring revenue. Wanilla manages the complete lifecycle — from purchase initiation to receipt validation to renewal tracking. Family Sharing and promotional codes are supported out of the box.

How Apple IAP is added to a Base44 app, step by step

Products are created in App Store Connect. Consumables, non-consumables or auto-renewing subscriptions, with pricing, free trials and introductory offers, plus the localised descriptions Apple requires before review.
StoreKit 2 is wired into the native layer. Purchases, renewals, refunds and family sharing are handled natively rather than through a web checkout, which is what keeps the app clear of guideline 3.1.1.
Entitlements are written back to Base44. Base44's database has no transaction table, so a small entitlements record is added and updated over the bridge whenever a purchase, renewal or cancellation happens. Your existing Base44 logic then reads one field to decide what a user can see.
Restore is implemented. Apple requires a visible restore path on any app selling non-consumables or subscriptions; missing it is one of the most common rejections.
Sandbox testing before submission. Every product is bought, cancelled and restored in Apple's sandbox, including the upgrade and downgrade paths, so review does not hit a dead end.

Stripe can stay in place for your web customers. The two are reconciled through the same entitlements record, so a subscriber who signed up on the web is recognised in the app and is not asked to pay twice.
