I’m ready to upgrade my website with real-time flight and hotel booking and to process every transaction through PayU. The site already has a basic front-end; what it needs now is solid back-end wiring to a travel API and a seamless PayU checkout flow. Travel API I have decided about the travel API and I will let you know when we discuss Payment Gateway All payments must run through PayU. The flow should: 1. create an order from the travel API response, 2. hand off to PayU’s checkout (redirect or embedded), 3. handle webhooks/callbacks for success, failure, or refund, and 4. update my database and send confirmation emails automatically. Deliverables • Fully functional flight and hotel booking endpoints integrated into the site • Complete PayU implementation with tokenisation, callbacks, and refund handling • Environment-based configuration (no hard-coded keys) • Clear setup & hand-over documentation plus Git commits for every milestone I’ll provide server access, existing code, and database schema. Code quality, security best practices, and well-commented logic are essential. If you’ve tackled similar travel + PayU projects, let’s get this integration live.
