Mobile payment integration connects Stripe, PayPal, Apple Pay, Google Pay, and app store IAP systems into your app. Engineers handling payments touch sensitive data (PCI compliance), implement security best practices, and debug payment provider APIs. Companies report 30-50% revenue increase when implementing proper payment flows. Senior mobile payment engineers earn 20-30% premium. Mastery takes 6-8 weeks.

What is Mobile Payment Integration

Mobile payment integration is the process of adding payment functionality to iOS and Android apps. It includes in-app purchases (subscriptions, one-time items), digital wallets (Apple Pay, Google Pay), and payment gateway integration (Stripe, PayPal). Payments in mobile are complex because the app must communicate with app stores (Apple, Google), payment processors (Stripe), and your backend server. Data flows through multiple systems, and PCI compliance (secure card handling) is mandatory.

❓ FAQ

What's the difference between Stripe and Apple Pay?

Stripe is a payment processor (company accepts credit cards). Apple Pay is a digital wallet (user's device handles card data). Use both: Apple Pay UI for user experience, Stripe backend for payment processing. They work together.

Should I use RevenueCat or implement IAP directly?

RevenueCat abstracts iOS and Android in-app purchases. One API handles both platforms' quirks. Recommended for apps with subscriptions. If only selling one-time items, native SDKs are fine. RevenueCat adds 5-10% cost but saves weeks of work.

How do I handle payment failures?

Implement retry logic. Network errors are temporary. Use exponential backoff. For user-initiated cancellations, show reason and offer support. Log all failures for debugging. Alert backend if critical (webhook didn't fire).

What's PCI DSS compliance?

PCI DSS (Payment Card Industry Data Security Standard) requires secure handling of card data. Never store raw card numbers in your app. Use tokenization (Stripe tokens, Apple Pay) instead. Backend handles sensitive data. Your app only touches tokens.

How do I test payments without real money?

Use test cards (Stripe, PayPal provide test credentials). Sandbox environments for Apple Pay and Google Pay. TestFlight for iOS testing. Firebase local emulator for backend. Never test with real cards in development.

Can I offer different prices on web vs app?

App stores discourage this. Best practice: same price everywhere. But apps can offer app-only discounts (time-limited promotions). Web-only pricing risks app store rejection.
