Selldone-G2A Bridge Developer Required

@hirujiyu

Hello, I have carefully reviewed your workflow and understand the complete process between Selldone and G2A. Key task I can help you :- ✅ Custom Stripe-like checkout page integrated with Selldone ✅ Dynamic gift card amount selection based on cart total ✅ Automatic price calculation, discount display, and final payable amount ✅ Customer redirection flow (Selldone → Custom Checkout → G2A → Selldone) ✅ Order/customer information capture for fulfilment tracking ✅ Option to automatically mark orders as paid in Selldone (if API access is available) ✅ Secure backend logic with proper validation and error handling My approach would be to build a middleware layer that handles the pricing logic, customer flow, order tracking, and communication between Selldone and the payment process while keeping everything reliable and easy to maintain. ✍️ Does Selldone provide API/webhook access for automatically updating order payment status? ✍️ Do you already have hosting/server access available for deploying the custom checkout and backend integration? I have experience building custom payment flows, third-party integrations, and automation systems, and I can start reviewing the workflow immediately. Looking forward to discussing the implementation in detail. Thank you.

Hello, I have carefully reviewed your requirements and can develop a reliable integration between your Selldone store and the G2A purchase flow. I will build a secure custom payment page, implement the backend logic to map your Selldone cart total to the appropriate G2A gift card amount, display the correct payment breakdown, handle the complete purchase flow, and redirect customers back to your store after a successful transaction. I will also automate order handling as much as Selldone allows and provide clear documentation for future maintenance. I have strong experience with custom payment workflows, API integrations, and eCommerce automation, and I'm confident I can deliver a stable, well-tested solution.

Hi, We reviewed your requirements and understand that you're looking to integrate your Selldone store with G2A to streamline the purchasing workflow while keeping the customer experience as seamless as possible. Our priority will be to build a secure, reliable integration that synchronizes pricing, order status, and customer information using *officially supported APIs and payment methods* where available. Our approach begins by reviewing the integration options provided by Selldone and G2A, then implementing the order flow, price mapping, payment handling, and post-purchase synchronization while ensuring the solution remains secure and maintainable. Our process includes: • Selldone Integration • G2A Product & Price Mapping • Custom Checkout Workflow (using supported payment methods) • Order & Customer Data Synchronization • Automated Order Status Updates • Email & Notification Integration • Secure Backend Development • End-to-End Testing & Documentation A couple of questions: • Does G2A provide an official API or partner integration for the gift card products you intend to sell, or will API access be available for this project? • Should successful purchases automatically mark the corresponding Selldone order as paid, or would you prefer an admin review step before fulfillment? Once we review the available integration options, we can recommend the best architecture and deliver a secure, scalable solution. Doomshell Team

Hi, this is Jorge from IT GLOBAL SOLUTION LLC in FL, United States. I’ve built payment-bridge style integrations between an e-commerce front end and third-party marketplaces/processors, similar to what you’re doing (Stripe-like hosted card pages with dynamic backend pricing/mapping). I’ll implement a dedicated “Stripe-like” hosted page inside your Selldone/PHP backend. It will render the card-entry UI (HTML/CSS/JS), submit payment/session data to a server endpoint, then on submit/redirect the backend will read the Selldone cart total (including your percentage markup), calculate the target G2A gift-card denomination, and resolve the closest matching G2A item by querying the most reliable method available. Prefer G2A official API/search endpoints; otherwise I’ll use a controlled server-side flow with stable identifiers. Before the final “Pay” button, I’ll surface the G2A real total (e.g., $109.47) and show a separate “Discount” line (e.g., $5.53 = 115 − 109.47) while keeping the actual charge aligned to G2A. After payment, I’ll handle the G2A success redirect back into Selldone plus server-to-server confirmation using returned identifiers and/or supported webhook/callbacks. Then I’ll update the Selldone order status as paid and attach the fulfillment payload (or, at minimum, order reference + buyer details). I’ll deliver clean, maintainable PHP with Git integration and docs so you can extend denomination mapping/UI long-term.

As a seasoned and dedicated web developer, my skills have been honed to expertly tackle complex tasks like your Selldone-G2A bridge project. I'm well-versed in API Integration, Backend Development, HTML, Web Development, and Website Design among others that all come together to deliver the custom Stripe-like interface you require. Importantly, I understand the need for a seamless user experience and will ensure that even though customers will be redirected to G2A, they'll ultimately return back to your Selldone website effortlessly. As you've highlighted, it's crucial to select the right gift card amount from G2A based on the total price of products in a customer's cart. My experience with various technologies including Laravel and PHP uniquely positions me to develop backend codes effectively accomplishing this task. Not only will I extract the right gift card amount as per G2A's system, but also factor in the necessary processing fees to present a direct and accurate total price watermarked on the Stripe-like page before payment.

@mayankinnovative

Hello, I reviewed your Selldone-G2A Bridge Developer Required project and it immediately stood out because reliable eCommerce integrations require secure API communication, real-time synchronization, and stable automation between platforms. Problem: Connecting two platforms can become challenging due to API limitations, inventory synchronization, pricing updates, order processing, and error handling, resulting in manual work and inconsistent data across systems. Solution: I can develop a secure integration bridge between Selldone and G2A with automated product synchronization, inventory updates, order processing, pricing management, API communication, logging, and reliable error handling. My experience includes API integration, Node.js, PHP, REST APIs, automation, and eCommerce platform development. Result: You will receive a stable, scalable integration that keeps both platforms synchronized, reduces manual effort, improves operational efficiency, and provides a reliable foundation for future enhancements. A few questions: • Should the integration support two-way synchronization for products, inventory, pricing, and orders? • Which APIs or authentication methods are currently available for your Selldone and G2A accounts? • Do you need real-time synchronization through webhooks, or would scheduled syncing be sufficient? • Should the bridge include an admin dashboard for logs, sync history, and error monitoring? Thanks

@cliftonc20

Hello, the core issue here is not the redirect itself but whether G2A provides a stable integration surface or whether this has to be driven as a browser-mediated checkout bridge. The real engineering risk is state reliability across Selldone, the custom payment page, G2A checkout, and final order reconciliation when price, availability, or confirmation behavior changes. I’ve built several production systems that sit between internal workflows and third-party web flows, including Playwright-based automation and backend orchestration where the external system is the least reliable part of the design. The closest relevant work is DocIntel AI for browser automation and pipeline control, and Enterprise ProxyTool Client App for designing clean boundaries between user-facing flow, execution flow, and reconciliation logic. I usually structure this as separate layers: Selldone order capture, denomination/pricing resolution, external checkout execution, and post-payment reconciliation. That separation matters because the bridge needs to handle redirects, mismatched totals, and incomplete returns without losing order state. For production use, I’d put most of the effort into idempotency, audit logging, and fallback handling around confirmation rather than the UI itself. If useful, I can sketch the order-state model and the reconciliation flow before any build starts. Clifton

@DesmondTwoTwo

⚡ I JUST COMPLETED A SIMILAR PROJECT. I have just handled a complex e-commerce integration, ensuring seamless transactions for customers. The main result you desire is a direct connection between your Selldone store and G2A listings. You need a custom payment page integrated with Selldone and automatic selection of the correct gift card amount from G2A based on the cart total price. To make the project clear and smooth, I will provide detailed progress updates and a user-friendly interface for easy navigation. REACH OUT, NO ONE CAN DO IT BETTER THAN I DO. Regards, Stefan.

@fahad508

Hello, I can build a secure integration layer between your Selldone store and G2A that dynamically maps cart totals to the correct G2A gift card purchase flow, while maintaining a Stripe-like checkout experience on your side. The solution would include a custom payment page, backend logic to calculate the correct G2A product selection (including fees and discounts), and a controlled redirect + confirmation flow to ensure the order is completed reliably and tracked properly. I have few questions to clarify: 1 does G2A provide any official API access for purchasing gift cards, or will this need to be handled through a controlled automation flow? 2 should the Stripe-like payment page be fully custom built inside Selldone, or hosted as a separate microservice? 3 do you want real-time order syncing back into Selldone (auto-mark as paid), or is email-based/manual reconciliation acceptable for phase 1? I’d be happy to discuss this further to ensure it meets your exact needs. Best Regards, Fahad
