Automate YouTube Video Alerts with n8n and Telegram

What This Workflow Does

This workflow checks a YouTube channel every 30 minutes for up to 4 new videos.
It makes sure only videos not already announced get sent to a Telegram group.
The workflow formats video titles and links nicely and sends them as messages.
This saves time and avoids missing video updates for the Telegram members.

The main problem it solves is removing the manual work of checking and typing new video info.
After setting up, it runs on its own, keeping the community informed fast.
