Hello! We are the Netly team, specializing in the development of custom web solutions and integration with Telegram, Viber, and Instagram. We use a modern stack: React (Next.js), Vue, TypeScript, TailwindCSS for the responsive frontend part, while the backend is implemented in Python (FastAPI, Flask) or Node.js, ensuring secure operation with payment system APIs and Nova Poshta, OAuth, and webhooks. We have experience in creating deep-link redirects, generating secure callback URLs, and automatically returning users to the bot after successful payment, including a backup page with a "Open bot" button. We are ready to develop a fully integrated end-to-end process, optimized for iOS/Android, taking into account data security and redirect speed.

Good day! 👋

We are The Dev Company, a team with experience in developing end-to-end solutions for integrating bots, payment systems, and logistics services. Your technical task is clear to us, and we have the necessary expertise to implement it.

Our experience

-> Frontend: React / Vue / native JS, responsive layout for iOS and Android, setting up deep links (Telegram, Viber, Instagram), automatic redirects after payment.
-> Backend: Node.js / Python / PHP, integrations with payment system APIs (Fondy, LiqPay, Stripe, etc.), integration with the "Nova Poshta" API (already integrated in past projects), generating secure callback-URLs, storing and processing orders in the database.
-> General: experience with OAuth, webhooks, data encryption (JWT, AES), building secure and scalable architectures.
Implementation option

1. Transition from bot to website
– The bot generates a unique link with parameters (platform, user_id, order_id).
– On the website, these parameters are stored in the session/database for further processing.

2. Order placement
– The user enters delivery details through integration with the "Nova Poshta" API.
– Payment is made through the integrated payment system.

3. Automatic redirect
– After payment confirmation, the frontend reads the platform and performs a redirect to the corresponding deep link (Telegram/Viber/Instagram).
– If the deep link does not work - the user sees a fallback screen with the message "Your order has been placed ✅" and a button to manually open the bot.

Advantages of our approach

– Fast and seamless UX (the user does not see "extra" screens after payment).
– Flexible integration for multiple messengers.
– Protection of user data and secure callback-URLs.
– Ability to scale the solution for additional platforms or payment services.

We would be happy to discuss the details, clarify the technology stack that is a priority for you, and prepare an implementation plan with timelines.

Best regards,
The Dev Company Expand
