App-to-Web Checkout

Every dollar that runs through Apple's in-app purchase loses 15 to 30 percent to commission. For U.S. iOS apps, App-to-Web Checkout gives you another path: a button on your paywall opens an external Stripe checkout in Safari, the user pays on the web, and the purchase links straight back into your app. No second login. No engineering project. You wire it up in the same campaign editor you already use for paywall tests, and you can turn it on for a segment without shipping a build.

The revenue you're handing to Apple

The math is simple and it stings. On a $99/year subscription, Apple's cut is real money you never see, on every renewal, forever. You can't A/B test your way around a commission rate, and rebuilding a compliant external purchase flow by hand — Stripe integration, deep links, entitlement syncing, redemption emails — is the kind of project that sits in the backlog for two quarters.

App-to-Web Checkout collapses that project into configuration. Apple's guidelines now permit U.S. App Store apps to show buttons and calls to action for purchase methods other than in-app purchase (Guideline 3.1.1(a)). Superwall is built to use that opening cleanly: present a Stripe path to the users it's allowed for, keep IAP for everyone else, and let the platform handle the plumbing.

What it actually does

App-to-Web Checkout, also called App2Web, links your iOS paywall to a Superwall-hosted Stripe checkout and brings the result back into the app:

• One tap to Safari. A call-to-action on your paywall opens an external browser straight to a hosted Stripe checkout page — not an embedded web view, which keeps the flow compliant.

• No authentication. The user doesn't create an account or sign in to pay. Their email or Stripe Customer ID is prefilled, so the page is ready to convert the moment it loads.

• Automatic linking back to the app. After payment, the user returns via deep link and entitlements update on their own. The SDK fires willRedeemLink() and didRedeemLink(result:) so you can react in code if you need to.

• Subscriptions, lifetime, and consumables. Stripe subscriptions and one-time prices both work, so you can run annual plans, lifetime access, or consumable purchases through the same path.

• Local-currency pricing. Stripe Adaptive Pricing lets eligible customers pay in their local currency at checkout.

• Revenue tracking with no extra wiring. When you check out through Stripe, web revenue is tracked automatically — unlike iOS and Android, which need manual configuration.

How it works

Setup is account configuration, not a code rewrite. You connect Stripe by installing Superwall's official Stripe app, add your products, and place them on the paywalls you want to route through the web. The app side needs the SDK set up to handle the return deep link, and for Apple Pay you add the *.superwall.app domain to Stripe's payment method domains.

Connect Stripe

From there it's the Superwall workflow you already know: build a campaign, target the audience that qualifies, and present the paywall. Because the Stripe path lives inside your normal campaign, you can test it the same way you test everything else — try the web button against IAP, test price points and offers on the checkout, and change the targeting without waiting on an app release.

Test it before you commit to it

You don't have to bet the funnel on a new purchase path. Run the web button as a variant against your existing IAP paywall and let the numbers decide. Test the checkout itself with sandbox products, then push it live to a slice of U.S. traffic and watch checkout conversion. If a segment converts better on Stripe, scale it up; if it doesn't, dial it back — all from the dashboard, no build required.

Test with sandbox products

Where teams use it

• Margin recovery on your best plans. Route U.S. annual and lifetime buyers to Stripe and keep more of every sale.

• Offers that need flexibility. Run promotions, trials, and pricing experiments on the web checkout without App Store Connect constraints.

• One funnel, two surfaces. Keep web and app monetization in the same campaign and audience system instead of splitting your growth stack across separate tools.
