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. We wrap your existing Base44 app in a native iOS shell, wire up Apple in-app purchases and subscriptions, handle App Store Connect, and ship the build to review — usually inside 14 days. 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 wrapper. 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 converts your Base44 web app into a native app 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.

Share the live URL of your Base44 app. Nothing is rebuilt — the existing build stays the source of truth.
2
Wire up native In-App Purchases
Wanilla wraps the app in a native iOS shell and injects real native In-App Purchases support, so the app is not a thin web wrapper under Apple Guideline 4.2.
3
Prepare the App Store listing
Bundle ID, App Store Connect record, privacy nutrition labels, screenshots, description and keywords are prepared for submission.
4
Configure pricing and paywall
Subscriptions and in-app purchases are created in App Store Connect and wired to StoreKit 2, with the paywall configured remotely so pricing changes need no new review.
5
Submit to Apple and go live
The build is submitted to App Review — typically within 24 hours of kickoff — and Wanilla handles any reviewer feedback until the app is approved.

Frequently Asked Questions

How long does it take to add Apple in-app purchases to a Base44 app?▾

Most Base44 apps go from web-only to live on the App Store with subscriptions in 10–14 days. We handle the native wrapper, StoreKit integration, App Store Connect setup, and submission to Apple review.

Do I have to rebuild my Base44 app in Swift?▾

No. Your Base44 app stays in Base44. Wanilla wraps it in a native iOS shell that exposes Apple's StoreKit APIs to your existing web code, so subscriptions, restore purchases, and receipts all work natively.

Is Wanilla a RevenueCat alternative for Base44 builders?▾

Yes. Where RevenueCat is a self-serve SDK you wire up yourself, Wanilla is a managed launch partner: we configure StoreKit products, server receipt validation, and the subscription lifecycle for you, then keep them running.

What does Apple take from in-app purchases?▾

15% in year one for every developer under the Apple Small Business Program (under $1M/year). We enrol you in the program during onboarding so you keep 85% from day one.

Can I sell physical goods through in-app purchases?▾

No. Apple restricts in-app purchases to digital goods and services. For physical goods, keep Stripe on web and use IAP only for digital subscriptions, credits, or premium features.

Will users be able to restore purchases on a new device?▾

Yes. We wire up native restore-purchases flows for every non-consumable and subscription product, so users sign in on any iPhone and get their entitlements back instantly.
