Custom Website Payment Gateway

@rajat07me

Your scope is clear, and I understand this is strictly for the web platform and Python backend with no mobile work involved. I can help extend the payment flow to cover subscriptions, wallet checkout, 3-D Secure, and tokenized returning-customer payments while keeping it aligned with your current service layer and database. I’ve handled complex integrations before, so I can work carefully around the existing architecture instead of forcing a messy rebuild. If you want, I can also review the current gateway flow first and point out the safest implementation path.

Hi, I have gone through your Custom Website Payment Gateway web development project. It looks straightforward at first, but payment processing often involves key details such as API authentication, transaction security, callback handling, and failed-payment flows that can cause issues later. I can outline a practical approach for integrating the gateway into your website. I have over 10 years of experience in PHP, JavaScript, Python, software architecture, web development, payment gateway integration, API development, and payment processing, and I'm excited to be part of your project. Let's discuss your website, preferred payment gateway, current technology stack, and integration requirements in the chat so I can recommend the most practical and cost-effective solution. ~ Rajesh

Hi, I reviewed your need to expand the ecommerce payment system for an owned gateway and a third-party processor, limited to the web platform plus python backend. You want recurring subscriptions, Apple Pay/Google Pay at checkout, the latest 3-D Secure authentication flow, and tokenised “card on file” linked to the customer for one-tap returns. I’ll extend the service layer, build/adapt Payment Gateway Integration APIs in PHP, connect them to your existing database, and wire the checkout UI so the flows trigger correctly and securely during payment. I focus on clean, reliable Web Development and Software Architecture, with responsive communication and easy handover. Let’s discuss here now.

Hi, I can help extend your existing Python payment service and checkout flow with subscriptions, Apple Pay/Google Pay, 3-D Secure, and tokenised saved cards. Before I start, I’d like to clarify a few things: 1. Which payment gateway/processor are you currently using? 2. Is the existing payment API and Python backend already in production? 3. Which database and backend framework are currently in use? 4. Do you already have access to the gateway’s tokenisation, wallet, and 3-D Secure APIs? Once I review the current payment flow and API capabilities, I can confirm the implementation approach and timeline. Best regards, Muhammad Rizwan LA

@extreamcode

Hi, You’re not just adding payment features , you’re removing friction from the exact moments where customers abandon checkout. The recurring billing, Apple Pay/Google Pay, 3-D Secure 2, and phone-linked tokenized card flow all point to a service layer that needs to stay clean, reliable, and fast under real payment pressure. I’ve built and integrated payment workflows, API layers, database-backed checkout logic, and front-end checkout improvements for ecommerce systems using PHP, Python, MySQL, and gateway APIs. I can extend your backend service layer, adapt the APIs, connect the flow to your current database, and wire the checkout UI so subscription renewals and one-tap returning payments feel seamless. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. How is your current gateway flow structured today for subscriptions, token storage, and 3-D Secure 2 handling? Looking forward to your reply so we can finalize the exact plan. Thanks, Asad

@seefattechnologi

Hi, Your existing payment gateway already handles transactions, so I will extend the payment layer without disrupting current workflows. I will implement recurring billing, Apple Pay, Google Pay, EMV 3DS authentication, and secure tokenized card-on-file payments while ensuring seamless API, database, and checkout integration with backward compatibility. I have extensive experience building secure payment systems and can start immediately. Thanks!!!

@onkarkulkarni8

Hello, I checked your "Custom Website Payment Gateway" project description, it looks like the focus is on delivering a clean, responsive website that works well across all devices. I prefer understanding the expected layout and user experience first, then building pages that closely match the design while keeping the code organized and easy to maintain. Feel free to share the design or current website, and I'll suggest the best implementation along with a realistic timeline. Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

@anirudhat

Extending your existing Python payment stack — across both your own gateway and the third-party processor — to add subscriptions, wallets, 3-D Secure, and one-tap card-on-file is squarely in my wheelhouse. I'll expand the service layer with a clean processor-agnostic abstraction so both gateways share the same recurring-billing, tokenisation, and auth logic, then add a scheduler/webhook flow for subscription renewals tied into your current database. For wallets I'll wire Apple Pay and Google Pay into the checkout UI with proper domain verification and merchant sessions, implement the latest 3DS2 challenge/frictionless flow, and store only network tokens linked to the customer's phone number for secure one-tap repeat payments. I'll build against sandbox first, keep everything PCI-conscious (no raw PAN storage), and test each flow end-to-end before go-live. I can start right away.

@ranjika08

I reviewed the brief and the feature set is well defined, which is helpful for execution. The combination of recurring payments, Apple Pay/Google Pay, latest 3DS flow, and phone-linked card tokenization will need both backend and checkout-side updates, and I can take care of that for the web stack you described. I’ll focus on making the new payment logic connect cleanly with your existing APIs and database structure. Happy to discuss the current gateway setup through the platform before starting.

Hello, Payment integration becomes truly valuable when the checkout feels effortless while the backend handles the complexity securely. Your requirement calls for extending an existing payment architecture rather than simply connecting another gateway, and that is where we can add value. At Doomshell Software Pvt. Ltd., we have extensive experience building and integrating payment APIs, recurring billing, secure checkout flows, wallet payments, and third-party payment services across web platforms. Our Approach: We’ll review your existing Python service layer and database structure first, then extend the APIs without disrupting current payment flows. We can implement subscription billing, Apple Pay/Google Pay, 3-D Secure authentication, tokenized card storage, and the required checkout UI while keeping security and error handling central to the architecture. Suggestion: We recommend keeping payment tokens isolated from sensitive card data and designing the payment layer modularly so additional processors or payment methods can be introduced later without major rewrites. We can handle the backend, API integration, database connectivity, checkout updates, testing, and deployment support. Let’s schedule a quick 10–15 minute call to review your current gateway architecture. We can demonstrate a relevant payment project and discuss the safest, most practical way to extend your existing system.
