What's included

End to end — from idea to a working product.

We deploy the product on the client's servers or in their cloud and hand it over up and running — with access credentials, documentation and team training.

  • Mini App with the native Telegram theme
  • Authorization via initData
  • Telegram Stars and external payments
  • Integration with the bot and broadcasts
  • Customer account and order history
  • Analytics and CRM

Our approach

We connect the bot, the Mini App and the backend into one system: the user is recognized automatically, data stays in sync and notifications arrive in the chat.

Outcome

A product with zero barrier to entry for people in Max, Telegram, VK and other messengers.

A Telegram Mini App instead of a website and an app

Telegram has more than 900 million users, and a Mini App opens for them with no install and no sign-up. That is why a Telegram Mini App often converts better than a mobile website: the user is already authenticated, and payments and notifications are built into the messenger. We explain how a Mini App differs from a bot and a website in what is a Telegram Mini App.

A Mini App almost always works together with a Telegram bot: the bot brings users in, reminds them and brings them back, while the app provides a convenient interface. An example of this combination is the coffee chain case study.
