Telegram bot and Mini App development
I build bots and apps inside Telegram: catalogs with filters, subscriptions to new offers, notifications, lead capture and AI assistants.
What is included
- A bot with a menu, commands and scenarios
- A Telegram Mini App with a catalog, filters and cards
- Subscriptions to notifications by criteria
- Admin tools and manual control when needed
- Auto-posting to channels and groups by topic
- Connection to your site and database
Who it is for
- Catalog projects: real estate, tickets, services
- Businesses that need leads straight from a messenger
- Channels and groups that need auto-posting
Result
A bot or Mini App that opens in one tap and works around the clock.
Examples
Da Nang House
A catalog of rental housing in Da Nang with a bot, a Mini App, subscriptions to new listings and auto-posting to a group.
HotTrip
An ecosystem around flights and tours: a portal, an AI bot, a Telegram Mini App, an API and an automated channel.

A Telegram Mini App catalog: API design, filters and subscriptions
A Mini App catalog rests on three parts: an API with filters and pagination, user verification by initData and a subscription worker that matches new items against saved criteria and sends notifications through the bot. One database and one API serve both the website and the Mini App.

A Mini App has no push of its own: notifications arrive as bot messages, and you can write to a user only after they start the bot or grant access with requestWriteAccess. To open the right screen use a web_app button or a direct link with the startapp parameter. Mark users who blocked the bot and stop messaging them.
Business · Oct 30, 2026How much a Telegram bot and Mini App cost: what the price is made of
A bot's price depends on scenarios, integrations and roles; a Mini App's price also depends on the interface, API and data. A simple bot costs far less than a catalog with subscriptions. Saving comes from launching a minimal version and describing the task clearly.
FAQ
Why a Mini App if I have a site?
It opens inside Telegram without leaving or logging in, supports notifications and is comfortable on a phone. The site stays for search and SEO.
Can users subscribe to new listings?
Yes. A user saves criteria and gets a message when a matching option appears.
