Good day.

I have worked with the integration of WayForPay in web/bot projects: generating payment links, processing callback/webhook, checking payment status, updating user access in the database.

I can implement for your Telegram mini app/bot:
— creating an invoice/payment link for the user;
— processing webhook from WayForPay after successful payment;
— changing the user's status in the database to "Paid";
— checking access before the main functions of the bot;
… — the command "Check payment status";
— an admin command for manual activation of access.

I will also consider security: checking callback data, protection against duplicate payment processing, logic for pending/approved/failed.

Before starting, we need to review the project stack, database structure, and deployment method.

Estimated time: 3–4 days after access to the code.
Estimated cost: 9500 UAH.

Hello.

WayForPay has integrated - including webhook signature validation and fallback status check via API. The standard scheme: invoice → webhook → status change in the database → check before each request.

To accurately estimate the time - it is necessary to look at the current code and database structure. Approximately 8–12 hours. Cost $120 - $180.

Oksana, it is important not just to "attach the payment," but to ensure that access opens reliably even if the webhook is delayed. I would implement: generation of WayForPay invoices, server callback with signature verification, status update in the database, fallback button for manual verification, and admin commands for access control. I have worked with WayForPay, and I also handle the existing code carefully. The integration of the establishment will take 1-3 days, and I will provide a cost estimate after a quick review of the project structure.

Hello! I am a Full-stack engineer with 9 years of experience in development on Node.js. I have significant experience integrating payment gateways, particularly WayForPay, into Telegram bots and web services. Working with payment data requires special attention to security and request queue processing, which I guarantee to implement in your project.

Answers to your questions:
Have I worked with WayForPay? Yes, multiple times. I have implemented both simple invoice generation and complex schemes with fund holding and recurring payments. I am well acquainted with their request signing system (hash) and status processing logic.

How long will the integration take? Given access to the code and documentation of the current bot — 3–7 working days. This includes development, testing webhooks on the sandbox, and final deployment.

Cost of work: Approximately 8,000 – 12,000 UAH, depending on the complexity of the existing bot architecture and the state of your database.

… My technical approach to your task:

Security: I will set up validation of the signature for each CALLBACK request from WayForPay to eliminate the possibility of payment status substitution.

Reliability (Idempotency): I will implement webhook processing logic so that repeated requests from the payment do not create duplicates in your database.

Fallback mechanism: The "Check Status" function will be implemented through a direct request to the Transaction Service from WayForPay, ensuring instant synchronization, even if the webhook is delayed on the network side.

Scalability: If you have Node.js, I will use clean modular services for payment logic.

I work as a sole proprietor, payment by contract is possible.

I am ready to review the module code and discuss integration details today. I am available!

Hello! I have extensive experience in development on Node.js (JS/TS) and integrating payment gateways into Telegram bots. The task with WayForPay is completely clear to me, especially regarding the secure processing of Callback requests.
My implementation plan:

WayForPay API: I will set up the generation of Purchase links with correct signature (hash) formation.

Webhook Handler: I will create a secure endpoint for receiving notifications. I will definitely add HMAC signature validation from WayForPay to avoid fake statuses.

Database Logic: I will carefully integrate status checks into your database (PostgreSQL/MongoDB/SQLite). I will implement both automatic updates and a manual check button via the TransactionStatus request.

… Admin Tools: I will add commands for access management through admin ID.
Answers to your questions:

Yes, I have experience working with Ukrainian payment systems (WayForPay/Monobank) and processing their APIs.

Integration into the existing code will take up to 3 days (considering thorough testing in Sandbox mode).

The cost is indicated above, I am ready to discuss details after reviewing the bot's code.

Oksana Ksenia, I have reviewed the description — the task is clear.

I will set up the generation of payment links through the WayForPay API with a correct HMAC-MD5 signature, implement a server-side webhook endpoint to receive notifications from the payment system, and automatically change the user's status in the database after payment confirmation. I will move the access check to a separate middleware/decorator — paid functions of the bot will be blocked for unpaid users until the transaction is confirmed. I will implement the "Check Payment Status" button with a direct request to the WayForPay API (transactionStatus) — this is a fallback in case of delay or loss of the webhook. Admin commands for viewing status by user_id and forcibly activating a record in the database are also included in the scope.

I am familiar with the WayForPay API and handling callback requests — payment logic of a similar type has already been implemented in my Telegram Mini App with cart/checkout flow and payment confirmation.

One clarification: is your bot's backend written in Node.js/TypeScript or Python? This affects the structure of the webhook module and the overall approach to integration.

Cost — 6400 UAH, timeframe — 2 days after access to the repository.

Do you already have a confirmed merchant account with WayForPay and a domain/URL for receiving notifications? And do you prefer to have simple admin commands in the bot or a separate lightweight web admin panel?

We have experience integrating WayForPay into bots and landing pages: generating invoices, verifying signatures, processing callbacks, idempotency, and logging payments. We work with Python (Flask/FastAPI), Postgres/Redis, read others' code well, and carefully integrate modules. We implement: payment links, webhooks, updating the status to "Paid," access verification in middleware, a "Check Status" button, admin commands/panel.

Yes, we have worked with WayForPay. Integration into existing code takes up to 3 days. Estimated cost: $500. We are ready to start after gaining access to the repository and WayForPay keys.
