Short answer

Can my AI change my Cal.com appointments?

Yes. Your AI uses unique booking IDs to find, move, or delete specific appointments. You'll see exactly what changed in your chat history.

Where every change lands.

The outcomes of your requests.

Depending on what you ask, your AI performs one of these four actions.

UPDATED

New meeting time

The AI moves your existing appointment to a new slot. Your calendar updates immediately with the new time.

REMOVED

Meeting canceled

The appointment is wiped from your schedule. The AI confirms the specific booking is gone.

CONFIRMED

Booking details

The AI pulls up the specifics of a meeting. You get the time, date, and ID for any existing booking.

ACTION

Human review needed

If the AI can't find a specific booking ID, it will ask you for more details before making changes.

The workflow

What your AI does when a request arrives.

The AI follows a logical path to ensure it touches the right appointment.

  2. Identify the ID
