I’m running a Laravel 12.54 application on PHP 8.3 and already have a payment gateway wired in. What I now need is native UPI support so customers can pay seamlessly through Google Pay, PhonePe and Paytm. Both one-time purchases and recurring subscription charges must work without manual intervention, including mandate creation, renewal and cancellation flows where each provider requires it. Key expectations • Clean, PSR-compliant code that drops straight into my existing service layer and respects my current gateway abstractions • Provider-specific callbacks, webhook handling and signature verification fully implemented • Clear instructions or migration scripts for any new tables / config values • Post-integration test cases that cover success, failure and timeout scenarios for single as well as recurring transactions Please factor in whatever SDKs, UPI intent flows or deep-link schemes each provider demands and make sure everything is documented enough for me to maintain going forward. Once you’re done, I’ll plug the module into staging and run end-to-end tests with live UPI IDs before moving it to production. I need to have it working without merchant key only no email

As a full-stack developer specializing in Laravel and MySQL, I have ample experience designing and building complex software solutions tailored to my clients' unique needs. Having already worked with payment gateways in Laravel applications, adding native UPI support for your app will be a smooth transition for me. I understand how critical it is for the new integration to respect your current gateway abstractions and table structures, which is why I always follow PSR-compliant coding standards and prioritize clean, maintainable code. In terms of UPI functionality, I am familiar with the various SDKs, UPI intent flows, and deep-link schemes required by Google Pay, PhonePe, and Paytm. My deep understanding of this ecosystem spans mandate creation, renewal, cancellation flows, and webhook handling. Moreover, I specialize in writing detailed software documentation that ensures seamless future maintenance. Prior to project delivery, I will thoroughly test your application for success, failure and timeout scenarios involving both single and recurring transactions. By doing so, we can address any potential issues before moving into production. Rest assured that my work is never complete until it exceeds client expectations.

Hello, I have reviewed your Laravel 12.54 and PHP 8.3 requirements and understand that you need UPI payment support integrated into your existing payment architecture while maintaining clean, PSR-compliant code. I can implement the integration within your current service layer, including: • UPI payment flows for supported providers • One-time payment processing • Recurring subscription and mandate handling (where supported by the provider) • Webhook/callback processing • Signature verification and transaction validation • Database migrations and configuration updates • Comprehensive test cases covering success, failure, cancellation, and timeout scenarios • Complete technical documentation for future maintenance My approach will be to preserve your existing gateway abstractions and ensure the implementation remains modular, maintainable, and easy to extend. Before starting, I would need access to the payment provider credentials/API documentation required for production UPI processing, as recurring payments and transaction verification depend on authorized merchant access. I can begin immediately and will provide a fully documented solution ready for staging and production testing. Regards, Bhupender

Hello, I can integrate UPI payment support into your Laravel 12.54 (PHP 8.3) application, including one-time payments, subscription workflows, webhook handling, signature verification, mandate management, and complete documentation. However, Google Pay, PhonePe, Paytm, and recurring UPI AutoPay transactions require valid merchant onboarding, API credentials, and compliance approval from the respective payment providers or an authorized payment aggregator. It is not technically possible to implement production-ready UPI payments without merchant credentials. If you already have an existing payment gateway account, I can extend your current architecture with a clean PSR-compliant implementation, migration scripts, test coverage, and seamless integration into your existing service layer. I would be happy to discuss your current gateway setup and provide the best implementation approach. Best regards.

Hi there, I've integrated UPI payment flows into Laravel applications before, covering all three providers you mentioned - Google Pay, PhonePe and Paytm - so I know exactly where each one diverges in terms of SDK requirements, intent flow handling and webhook signature schemes. What you'll get from me: ✅ A PSR-compliant UPI module that fits into your existing abstractions - I won't touch what's already working ✅ One-time and recurring flows for Google Pay, PhonePe and Paytm, including mandate creation, renewal and cancellation ✅ Webhook handling and signature verification for all three providers ✅ Intent flows and deep-link schemes set up correctly per provider ✅ Migration scripts and config notes for anything new ✅ Tests for success, failure and timeout - single and recurring both covered Regarding your note on merchant key - understood, I'll build the integration around sandbox/live credentials you supply directly, no assumptions made on that front. Just share your provider dashboard access and we go from there. Delivered in 2 days for $10. Ready to start immediately. Looking forward to it!

Hello, I am a Full-Stack Developer with strong experience in Laravel, API integrations, payment gateways, webhooks, and backend architecture. I can help integrate UPI payment support into your Laravel 12.54 (PHP 8.3) application while maintaining clean, PSR-compliant code that fits your existing payment abstraction layer. My approach includes: • Integration of supported UPI payment flows • Webhook and callback implementation • Signature verification and transaction validation • Support for one-time payments and recurring billing workflows where supported by the provider • Database migrations and configuration setup • Comprehensive testing for success, failure, cancellation, and timeout scenarios • Clear documentation for future maintenance I have experience working with Laravel service layers, third-party APIs, payment processing systems, and production-grade backend applications. The delivered code will be modular, maintainable, and follow Laravel best practices. Before starting, I would like to confirm which payment provider accounts and merchant credentials are available, as recurring UPI mandates and automated renewals typically require provider-side merchant onboarding and API access. I am available to start immediately and can provide regular progress updates throughout the project. Looking forward to discussing the details.

UPI recurring (mandates) is the tricky part here. PhonePe and Google Pay both support UPI AutoPay via NPCI mandate flow, Paytm has its own mandate API. Each has different webhook schemas and signature verification. I'd build a unified service layer so your existing gateway abstraction stays clean. Quick question: do you need all three providers at launch, or can we start with one (say GPay/PhonePe via UPI AutoPay) and add Paytm in a second milestone? Delivery: PSR-compliant Laravel module, webhook handlers + signature verification for each provider, migration scripts for new tables, test cases for success/failure/timeout on both one-time and recurring. Documented enough to maintain without me. INR 1200, milestone split (one-time flow done / recurring + all providers done). Valerii
