System Documentation

What problem does it solve?

This Skill enables secure Telegram-based user authentication for web applications by integrating the Telegram Login Widget and validating signatures to verify user identity.

Core Features & Use Cases

  • Telegram Login Widget integration for browser-based authentication
  • HMAC-SHA256 signature validation for Login Widget data and WebApp initData
  • Session cookies and per-request API protection via middleware
  • Telegram Mini App support with initData-based authentication
  • Enforce allowed user IDs to restrict access to trusted accounts

Quick Start

  1. Set up a Telegram bot with BotFather and obtain a bot token.
  2. Link your domain with BotFather using /setdomain and ensure domain matches where your login widget is hosted.
  3. Implement backend validation for both Telegram Login Widget data and WebApp initData using SHA256(bot_token) and HMAC-SHA256("WebAppData", bot_token) respectively.
  4. Inject bot username into your frontend and render the Telegram Login Widget.
  5. Handle the login callback to create a secure session cookie and protect API endpoints with the middleware.
