This one n8n workflow does 5 things for a Telegram community, built it for a client last week on Upwork. Let me show you the demo first. Watch what happens when I send /start. The bot instantly checks if this is a new or returning user. Since this is a new user, it sends a welcome message and asks them to pick their topics. I'll select a topic now, and you can see the notification comes back immediately saying it's processing. And there it is, the confirmation message. Fully working, real time.
