Payment for Telegram bot users through their own payment system (payment gateway)

Budget: 100 EUR Deadline: 5 days

Good day!
I have experience working with custom PHP (AJAX) projects and integrating European payment systems with webhook/callback logic. I am ready to implement user registration, linking to Telegram via link_token, processing payment statuses with signature verification, idempotency, and subscription updates, as well as integration with the bot API with retry and logging. I will conduct complete end-to-end testing taking into account edge cases and legacy nuances.
I would be happy to collaborate! :)

Hello.
I carefully read the project description. I have experience working with web projects, Telegram bots, and integrations through API. I can carefully implement user registration, linking accounts to Telegram, processing payment status, and transmitting events to the bot.
Before starting, I suggest briefly discussing the current architecture of the site and the method of integration to make the solution stable and secure.
I am ready to work in stages: first a basic working version, then testing and refinement.
I would be happy to discuss the details and propose the optimal implementation option.

Good day Polina,

I will create user registration with the necessary forms and endpoints. I will implement mechanisms for linking the account to Telegram, including token generation and its storage considering TTL. I will handle the "paid" status through integration with the payment system, including event validation and protection against duplicates.

The deadline for completing all tasks will be 4-5 days. If you are ready to discuss the details and next steps, let me know.

Hello.

I have worked with custom PHP projects, integration of payment systems, and Telegram bots. I have implemented account linking through tokens, webhook processing, and protection against duplicate events.
I can implement:
- registration with proper validation and hashing
- the mechanism for linking Telegram via a one-time token
- processing callbacks from the payment system with signature verification
- protection against duplicate charges (idempotency)
- sending events to the bot with retry and logging
I will carefully analyze the current code and take into account legacy nuances.
I look forward to collaborating. Expand
