Manage User Authentication with Telegram, Redis Cache and Google Sheets

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.
