The project is about integrating Paytm or Razorpay SDKs into a mobile marketplace built with Xamarin. The goal was to enable users in India to make seamless payments and route them to respective vendors within the platform. The integration needed to comply with Indian payment norms while ensuring a smooth and secure checkout experience.

The client needed a robust payment gateway integration that supports UPI, credit/debit cards, and wallet transactions for Indian users. The system also had to handle transaction routing to vendors, manage refunds, and provide real-time payment status updates. It was essential to maintain compliance with Indian regulatory standards, including KYC and transaction logs.

We successfully delivered a complete SDK integration solution with:

• Integration of Paytm and Razorpay SDKs into Xamarin-based apps
• Custom routing logic to direct funds to specific vendor wallets
• Secure token-based transaction flow and compliance with Indian banking norms
• Real-time transaction monitoring, failure fallback handling, and refund workflows
• Admin dashboard to track payment statuses, disputes, and logs
• End-to-end testing and deployment on Android and iOS marketplaces
