About Telegram Mini Apps

This is the reference for Telegram Mini Apps, the web applications that run inside Telegram. It describes how a bot launches an app, what the JavaScript API gives you, how theme and viewport work and how launch parameters are passed.

The page uses the Durger King bot as a live example and covers several launch modes, including inline keyboard buttons and the attachment menu. Everything about layout inside Telegram starts here, so read it before reaching for a third-party SDK.

Highlights

  • Official reference from Telegram
  • Covers launch modes and the JavaScript API
  • Live example in the Durger King bot
  • Start here before any third-party SDK
