How It Works

  • Telegram bot listens for messages and uses chat ID as the unique user identifier.
  • Checks Google Sheets for existing users; registers new users if not found.
  • Caches active sessions in Redis for fast lookup and login-state handling.
  • Stores and retrieves user data (UserID, Name, Telegram Chat ID) in Google Sheets.
  • Can be triggered by other n8n workflows to fetch or update user/session data.

Setup Steps

  • Obtain Telegram Bot token, Google Sheets “Users” sheet with API credentials, and a Redis instance.
  • Import the n8n workflow and configure Redis, Telegram Bot, and Google Sheets credentials.
  • Expect 30–45 minutes to complete workflow import, Redis setup, and API wiring.
  • Refer to sticky notes inside the workflow for exact field mappings and node configurations.
