FAQ
How is a Mini App different from a Telegram bot?
A bot works well for conversations and notifications; a Mini App suits catalogs, schedules and multi-screen interfaces. They often work together.
How is a Telegram user authenticated?
The backend must validate the initData signature and age. A Telegram ID or permission sent by the browser is not proof of identity.
Can the Mini App connect to an existing bot?
Yes. We review the current commands, backend and data, then decide which actions stay in chat and which belong in the interface.
