ASP.NET ICICI Payment Integration

@jethwafenil

Hi, I can integrate the ICICI Bank payment gateway into your existing ASP.NET (C#, SQL Server) application with clean, secure, and fully tested server-side implementation. I have previously implemented multiple payment gateways in web applications (one-time payments, subscriptions, refunds), so I clearly understand tokenization, secure callback handling, sandbox/live switching, and keeping systems out of PCI scope by avoiding card storage. Here’s what I’ll deliver: • Clean server-side integration for payments, recurring billing, and full/partial refunds • Web-configurable credentials (sandbox/live switch via config, not code changes) • Proper success/error handling back to UI • End-to-end sandbox testing before production • Inline comments + short deployment/maintenance guide • Secure token-based approach (no card data stored) I currently have 6 clients with 5-star reviews, which reflects my reliability and technical capability. I’m new to this platform but not new to development. You only need to release payment after the full integration is completed and demonstrated. Once done, I’ll share a complete demo (video or live walkthrough on AnyDesk) so you can verify everything works perfectly before paying. If you share the existing codebase, I can start immediately and complete this efficiently. I’m offering a competitive rate while maintaining high-quality implementation. Just message me once and we can get started right away.

You’re already at the finish line here — the app is live-ready, it just needs a solid ICICI gateway layer wired in correctly. From your brief, the core goal is a clean ASP.NET (C#) integration that supports one-time payments, subscriptions, and refunds, all token-based so no card data ever touches your server. Environment switching via config and proper sandbox validation are clearly non-negotiable, and that makes sense for payments. I’ve handled similar bank gateway integrations in ASP.NET where the main work is careful API handling, signature validation, callbacks, and making sure failures are visible and traceable without breaking the UI flow. I’m comfortable working directly in existing codebases and keeping changes isolated and well-documented so your team can maintain it later. My approach would be to wire the ICICI APIs server-side first, validate all three flows end-to-end in sandbox, then clean up config handling and callbacks before handoff. Do you already have ICICI’s API docs and sandbox credentials, or should I work from their latest standard integration guide? Thanks for the clear scope — that always makes payment work smoother.

Hello, I can help you integrate ICICI Bank’s payment gateway cleanly into your existing ASP.NET + SQL Server application. I have strong experience building secure server-side payment and API integrations, including one-time payments, subscriptions, and refunds, while ensuring PCI compliance by avoiding card data storage. I will implement token-based flows, configurable credentials, and callback handling so you can easily switch between sandbox and production without code changes. The integration will cover all three flows (one-time, recurring, refunds), include proper error handling, and be fully tested in ICICI’s sandbox before handover. I’ll also provide brief documentation and inline comments so your in-house team can maintain it confidently. Before starting, I’d like to confirm: 1. Are you using ICICI’s hosted checkout or API-based flow? 2. Do you already have sandbox credentials and callback URLs ready? Looking forward to discussing this further. Regards, Dhaval P.

Hello, I can integrate the ICICI Bank payment gateway cleanly and securely into your existing ASP.NET (C#, SQL Server) application. I have hands-on experience integrating multiple banking and e-commerce payment gateways and understand the importance of PCI-safe, token-based implementations with reliable server-side handling. I’ve already integrated and deployed gateways including PayPal, Stripe, Moyasar, EasyPaisa, JazzCash, and Al Rajhi Bank APIs, covering one-time payments, recurring billing, and refund workflows. This background allows me to adapt quickly to ICICI’s API structure and edge cases. What I’ll deliver Robust server-side C# integration for one-time payments, subscriptions, and full/partial refunds. Config-driven setup Clear success/error responses surfaced to the UI Clean, well-commented code plus a short deployment & maintenance guide for your in-house team. Approach I’ll plug the gateway into your current solution with minimal disruption, follow ICICI’s best practices, and ensure all flows work reliably before hand-off. The focus will be correctness, security, and long-term maintainability. I’m ready to start immediately and can complete this as a self-contained delivery with clear proof of working transactions. Best regards, Shahzaib

Hello, I have 4.8+ years of experience in ASP.NET (C#) and SQL Server, including third-party API and payment gateway integrations. I can securely integrate the ICICI Bank payment gateway to handle one-time payments, recurring billing, and full/partial refunds using a token-based approach (no card storage). The solution will support config-based sandbox/production switching, clear success/error handling, and full end-to-end sandbox testing before go-live. Clean, maintainable code and deployment documentation will be included. Best regards, Kirtan Rajodiya
