⚒️ Manage User Authentication with Telegram, Redis Cache and Google Sheets
⚡ 352 views · ⚒️ Engineering
Description
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.
