Hi, As per my understanding: You need to integrate a secure credit/debit card payment system into your application so users can complete transactions smoothly. The integration should connect your app with a reliable payment gateway, handle card processing securely, and ensure proper transaction flow while following required security standards. Implementation approach: I will first review your app’s current architecture and recommend the most suitable payment gateway such as Stripe, PayPal, or another provider depending on your region and requirements. Then I will implement secure card processing using the gateway’s SDK or APIs, ensuring PCI-compliant handling of card data. The integration will include payment request handling, transaction confirmation, error handling, and webhook-based status updates. I will also test the system using sandbox transactions to verify successful payments, failures, and refund scenarios before deployment. A few quick questions: Which platform is your app built on (web, React Native, Flutter, etc.)? Do you already have a preferred payment gateway account? Will the app require recurring payments or one-time transactions only? Do you need additional features like refunds or payment history?
