GST Pro API Integration

@NaveenSingh09

Hello, GST Pro API Integration will be implemented by first reviewing the official documentation and staging environment. I will set up authentication, environment switching, and robust error handling. Next, I’ll embed real‑time GSTIN validation into the customer‑onboarding form and create services for invoice push/pull, status updates, and reconciliation callbacks. E‑way‑bill generation and retrieval will be added to the dispatch module with clean JSON responses. Unit and end‑to‑end tests will cover success cases, common failures and graceful fallbacks. I’ll document the code and provide concise implementation notes for your in‑house team. Throughout the process I’ll stay available for questions and quick code reviews to keep momentum high. Once the staging site passes all tests, I’ll deploy the same changes to production with real credentials. Best Regards Naveen Thakur

wiring up APIs is quite simple. Do you have more information on the scope of the endpoints required? I have put in a placeholder bid in the meantime. Unless the list is very long or has unexpected complexities I don't expect the work would take more than a day or two.

ets integrate GST Pro REST API seamlessly into your PHP billing platform. GET A FREE DEMO of the GST API workflow before we start. I will connect your existing PHP system with GST Pro REST services so GSTIN validation, invoice synchronization, and e-way bill generation happen automatically inside your platform. The integration will include secure authentication, sandbox/live environment switching, reliable JSON responses, and strong error handling so your UI stays fast while data flows smoothly. I will also implement real-time GSTIN checks in your onboarding form, automated invoice push/pull with status updates, and full e-way bill generation within the dispatch module. I WILL Built using PHP REST API integration, MySQL, secure token authentication, and structured logging with unit and end-to-end testing.

I understand you require seamless integration of the GST Pro REST API into your custom PHP billing platform, covering GSTIN checks, invoice synchronization, and e-way-bill creation without affecting UI performance. Your need for robust error handling, environment switching, and test coverage aligns with a comprehensive backend enhancement. With over 15 years of experience and 200+ projects completed, I specialize in PHP, API integration, and MySQL database design, making me well-suited to wire the GST Pro endpoints cleanly into your existing codebase. My background in backend development ensures reliable data flow and clean JSON responses, critical for your real-time validation and dispatch modules. I will start by setting up authentication and sandbox/live environment toggling, then integrate GSTIN validation into your onboarding form followed by invoice data push/pull and e-way-bill automation. I’ll implement unit and end-to-end tests to cover success and failure scenarios and provide clear documentation for your team. This process typically takes about 10-12 days to complete and test thoroughly. Let’s discuss your timeline and any specific expectations to get this integration running smoothly.

Hi there! I'm new to Freelancer but not new to PHP and REST API integrations. I'd love to prove myself on this project, no job too small for me to give 100%. Your GST Pro integration is right in my wheelhouse. I work daily with PHP backends, MySQL databases, and REST APIs. I can wire up the GSTIN validation, invoice sync, e-way bill generation, and callback handling cleanly into your existing codebase. Here's my approach: - Set up proper authentication with environment switching (sandbox/live) - Integrate GSTIN validation into your onboarding form with real-time feedback - Build the invoice push/pull with reconciliation callbacks - Add e-way bill generation to your dispatch module - Write unit and integration tests for all endpoints - Document everything so your team can maintain it easily I'm available to start immediately and can have this delivered within 2 days. Happy to do quick code reviews and PRs to keep things moving fast. Looking forward to working with you!
