For my third automation, I wanted to build something close to what a real consultant would actually use: when someone books a meeting with me, everything happens automatically.
The Idea
If someone books a call with me, I shouldn't have to send the confirmation email or note it down manually. So I connected three tools:
Cal.com → Gmail → ClickUp
- Cal.com (trigger): People use my booking link to schedule a 15 or 30-minute meeting. Cal.com already collects their name, email and an optional message, so I didn't have to build a separate form.
- Gmail: Once someone books, an email goes out to them automatically, confirming I received their booking and the meeting time they chose. [Add one line if you handled the "not available" case differently.]
- ClickUp: A task is created with the name of the person I'm meeting, so I can keep track of my meetings in one place. [Screenshot of the ClickUp task]
The Silly Mistake That Wasted My Time
My trigger wasn't working. No output at all. I kept going back to Cal.com, creating new events, and waiting for the trigger to fire. Nothing happened.
The problem: creating an event is not the same as making a booking.
- Events: where you create your meeting types (for example, a 15 or 30-minute call)
- Bookings: where you see the meetings people have already booked, like a calendar
- Links: where you open your public booking link, the one other people use to book you
My trigger only fires when a booking is made. So I was creating events over and over, which never triggered anything.
The fix: to test the trigger, open your booking link and book a 15 or 30-minute slot yourself, using a second email address or a friend's, as if you were a real customer. The moment that booking is made, the trigger fires.
If you're a beginner and your trigger isn't working, check this first. It's a small thing, but it can cost you hours, and I'm sharing it so it doesn't cost you yours.
What I Learned
- Triggers listen for a specific action. Know exactly which action starts your workflow, then test by doing that action, not something similar.
- Test like a real user. Book through the public link instead of assuming that setting things up will trigger the workflow.
- Three simple tools chained together can already feel like a real business process. Booking, confirmation and tracking all happen without me touching anything.
- It's okay to be new to a tool. This was my first time using ClickUp, and I used it very roughly, just for testing. I'll organize it properly once I learn it better.
What's Still Missing
This is a test setup. My ClickUp tasks aren't organized into proper projects yet, and the automation doesn't handle things like cancellations or rescheduling.
If you've used Cal.com, n8n or ClickUp in your workflows, what's the most useful thing you've automated? I'd love some ideas!
