Connect Google Calendar with Topcalls AI voice agents

The Create Event action opens a calendar event in the correct Google Calendar the second a caller confirms a demo time. Topcalls sets the title, description, video link, and invitees, then reads the confirmed time and location back on the phone before ending the call.

The Find Busy/Free Periods in Calendar action returns the caller's busy and free windows across their Google Calendar. Topcalls uses the result on the phone so the AI voice agent can offer a real slot instead of a generic time that will land on top of an existing meeting.

The Add Attendees to Event action extends an existing Google Calendar event with new invitees. Topcalls uses it during a call when a buyer says they want a colleague added to the demo, so the meeting stays in place and everyone gets a fresh calendar invite in seconds.

The Event Start (Time Before) trigger fires a fixed amount of time before a Google Calendar event begins. Topcalls picks up the trigger, dials the invitee, and reads a short reminder script in the invitee's language, so no-shows drop and meeting attendance stays high across the pipeline.

The Event Cancelled trigger fires the moment a Google Calendar event is deleted or cancelled. Topcalls consumes the event and places an outbound call to the invitee to reschedule, so cancelled meetings turn into a booked slot on the calendar rather than a lost opportunity.
