Ensure tokenization, 3-D Secure, and proper error handling are implemented for a secure checkout experience. 2. Swift Implementation & UI Integrate the payment SDK cleanly into your current Swift codebase. Build a smooth, minimal UI that matches your app’s look—cart review, card entry, Apple Pay sheet, and success/failure screens. 3. Server-Side & Webhooks Connect the iOS app to your existing Node.js backend to log transactions, refunds, and receipts accurately. Implement necessary webhooks and hooks for real-time updates. 4. Testing & Deployment Support Perform end-to-end testing in TestFlight to ensure the flow works perfectly. Provide technical notes and a walkthrough to guide you through deployment and App Store review. I focus on clean, maintainable code, security best practices, and smooth user experience, so your users can pay without friction and your app passes App Store scrutiny.

Hello, I reviewed your requirements and can confidently integrate a secure, App Store–compliant payment flow into your existing Swift-based iOS app without disrupting the current codebase. I have hands-on experience implementing Stripe and Apple Pay in iOS apps, including tokenisation, 3-D Secure (SCA), robust error handling, and smooth in-app checkout flows. I’ll recommend the most suitable gateway based on your needs, with Stripe being a strong default for cards + Apple Pay support. How I’d approach this: Configure and integrate the payment gateway SDK in Swift Implement in-app checkout UI (cart review, card entry, Apple Pay sheet, success/failure states) aligned with your app’s design Handle tokenisation, payment intents, and 3-D Secure flows cleanly Connect server-side Node.js webhooks for payments, refunds, receipts, and status updates Thorough sandbox testing and TestFlight validation Ensure the implementation meets Apple App Store review guidelines Deliverables: Updated iOS source code Server-side webhook integration (Node.js) Basic technical documentation Short walkthrough call covering setup and deployment I focus on clean, secure implementations, clear communication, and smooth handover so you’re comfortable maintaining the payment flow after delivery. I’m ready to start once access is shared and can move efficiently to completion. Best regards, J15TechLab
