Telegram Mini App · payment · statuses
A store in Telegram
A store for a fictional coffee roastery: the catalog opens as a Mini App right in Telegram or as buttons in the chat. The order is paid with a test card and then moves through statuses on its own — the bot sends notifications like a real store.
Scenario: Zerno Roastery — coffee, drip bags and brewing gear. The store is fictional; no money is charged.
Open the demo
The bot replies in Russian: it was built for Russian-speaking customers. Example phrases come with translations.
The same Mini App that opens inside Telegram; an order placed in the browser is handed to the bot via a link.

What the demo shows
How to try it
Open the bot
The “Open in Telegram” button or the QR code. Press “Start”.
Fill your cart
The “🛍 Открыть магазин” (Open store) button under the input field opens the Mini App. Or skip it and use the catalog buttons in the chat.
Pay with a test card
Number 1111 1111 1111 1026, any future expiry date, CVC 000. No money is charged.
Track the status
Within a couple of minutes the order goes through packing and delivery, and the bot sends notifications. All orders: the /orders command.

No paid neural networks
No neural network is needed here, and that’s a position too: a store needs a reliable catalog, payments and statuses, not “AI for the sake of AI”. In a production project a model can be added where it helps — for example, recommending coffee by taste.
The demo runs without OpenAI, YandexGPT or GigaChat API keys. Wherever a production system calls a model, there’s a local stub with the same interface — so the demo is free, always available and never makes things up.
What a production project adds
- Catalog and stock from MoySklad, 1C or your CRM
- Live payments via YooKassa, CloudPayments or T-Bank with fiscal receipts (Federal Law 54-FZ)
- Statuses from the delivery service (CDEK, Yandex Delivery) and the warehouse system
- Broadcasts, promo codes and one-click repeat orders

The Warrior Within
The catalog adapts to the buyer: a Mini App inside Telegram, buttons right in the chat for those who dislike apps, and a regular page in the browser.
Developer’s comment
Anton Goncharov
AI systems developer · Python
For business
- Buyers don’t need to install an app or register: the catalog, cart and payment are inside Telegram, where they spend their day anyway.
- Order statuses arrive on their own — fewer “where’s my order?” questions to support.
- A repeat order is one message from the bot, not an ad budget for winning the customer back.
For developers
- The Mini App is a page of this same Next.js website; its theme adapts to Telegram. Outside Telegram it works in the browser and hands the order to the bot via a link.
- Only the bot calculates prices: the Mini App sends SKUs and quantities, so the total can’t be tampered with in the browser.
- Payment is Telegram Payments with a test provider; a background task in the bot moves order statuses and sends notifications.
Tips
Tip 01
Never trust an amount that comes from the client — neither from a Mini App nor from a website.
Tip 02
Keep the catalog as chat buttons as a fallback: some buyers won’t open the Mini App.

Service booking in Telegram and Max
The bot books barbershop appointments: service, barber and free time via buttons or in a single phrase, prepayment, a reminder with “I’ll come” and “Reschedule” buttons, rescheduling, cancellation and the schedule as the administrator sees it.
