UPI payment integration requires choosing between a direct bank or NPCI tie-up (for large consumer apps) or using a licensed payment gateway or aggregator. Most developers use intent or collect APIs via an aggregator. UPI integration uses Intent Flow for quick app-based payments, Collect/VPA for UPI IDs, and AutoPay for recurring payments. Implementation involves KYC and gateway setup, backend order creation, payment triggering, and secure webhook-based payment verification.
For fintech apps in 2026, both Flutter and React Native are strong choices. Flutter is better for performance and security, making it ideal for apps with real-time charts and sensitive data. React Native is better for faster development, easier hiring, and large-scale team growth due to its bigger developer ecosystem.
