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.

Hello, I went through the project, with flight and hotel APIs, prices and availability can change quickly, you can end up with successful payments for bookings that are no longer available. My approach would be: • Connect the site to the selected travel API and create secure backend endpoints for search, pricing validation, and booking • Create the order server-side from the confirmed API response before sending the user to PayU • Implement PayU checkout with proper callback and webhook handling for success, failure, and refunds • Update the database, send confirmations, and keep logs for payment and booking status • Use environment-based configuration and clean version-controlled milestones as requested I’m a full stack developer experienced with API integrations and payment gateways, and I’d be happy to help get this connected smoothly.

Hi, After checking your requirements I understand that this is a backend-heavy integration and aligns well with my experience in API orchestration and secure payment gateway flows. I can implement: • Travel API integration for flight and hotel search, pricing, availability, booking, and order creation. • Structured booking pipeline: API response → internal order creation → PayU checkout → webhook validation → DB update → automated confirmation emails. • Full PayU integration including tokenisation, secure hash generation, callback verification, refund handling, and idempotent webhook processing. • Environment-based configuration (separate dev/staging/prod configs, no hard-coded credentials). • Clean Git-based milestone commits with documented architecture decisions. Implementation focus: – Secure server-side validation of all PayU callbacks. – Transaction state management (pending / paid / failed / refunded). – Proper logging and retry-safe webhook handling. – Well-structured service layer for maintainability and future API swaps. Before finalizing cost and timeline, I’d like to review your existing codebase, tech stack, and database schema to assess integration complexity. After that, I’ll provide a precise estimate. Let’s review the architecture and move this toward production-ready stability. Best, Shailender

Hello, I can assist you in connecting real time flight and hotel booking to your website and set up PayU for all payments. Since your frontend is already ready, I will focus on the backend work. I will connect your chosen travel API so your site can show live flight and hotel data. When a user selects a booking, the system will create the order from the API response and then send the user to PayU checkout to complete the payment. I will set up the full PayU flow including handling successful payments, failed payments, refunds, and webhooks. After payment, your database will update automatically and confirmation emails will be sent to customers. All API keys and payment details will be securely configured using environment settings. The code will be clean, secure, and well commented. I will also provide proper documentation and push clear Git commits for every milestone. Once you share the travel API details, server access, and your existing code, I can start the integration and make everything live smoothly. Looking forward to working with you.

Hello there, 8 years of experience in API integration and payment gateway work across PHP and Python. Your PayU flow — order creation from travel API response, checkout handoff, webhooks for success/failure/refund, DB updates, confirmation emails — is a pattern we know well. Travel API results get cached in MySQL, order record created before PayU redirect. PayU callback handles user-facing redirect while the webhook is source of truth for payment status. Webhooks processed async via job queue so your main thread never blocks. We'd stay in PHP with a clean service layer separating travel API, PayU logic, and order management. PayU's PHP SDK handles tokenisation and hash verification natively. Config via `.env` with `vlucas/phpdotenv` — no hard-coded keys. Refunds via PayU's server-to-server API with status polling since refund webhooks can be unreliable. On an enterprise supply chain platform we handled 60,000+ transactional records with queue-based processing and webhook orchestration across multiple third-party APIs — similar orchestration complexity to your booking pipeline. Biggest risk: payment confirmed but travel API booking fails. We'd hold orders in "pending-confirmation," confirm the travel booking first, then capture — auto-triggering a PayU refund if it fails. Three milestones: travel API integration (Week 1), PayU flow with callbacks (Week 2), refund handling plus docs and handover (Week 3). Naveen Brainstack Technologies
