What This Workflow Does

This automation solves the headache of manually managing Calendly appointments across multiple platforms. It automatically handles booking confirmations, cancellations, and rescheduling events while keeping all your systems perfectly synchronized.

The workflow captures every booking change in real-time, updates Google Calendar accordingly, sends confirmation emails through Gmail, logs all meeting data to Google Sheets for record-keeping, and notifies your team in Slack about scheduling changes. This eliminates the risk of double bookings, missed appointments, and manual data entry errors.

How It Works

1. Calendly Event Trigger

The workflow starts when any booking activity occurs in Calendly - whether it's a new appointment, cancellation, or reschedule. The trigger captures all relevant details including attendee information, meeting time, and event type.

2. Google Calendar Synchronization

The system automatically creates, updates, or removes calendar events based on the Calendly activity. This ensures your Google Calendar always reflects the most current appointment status without manual intervention.

3. Automated Email Communication

Customized confirmation emails are sent through Gmail with all meeting details. For cancellations or reschedules, appropriate follow-up emails are triggered to maintain professional communication.

4. Google Sheets Logging

Every booking action is recorded in a Google Sheet with timestamps, attendee details, and meeting notes. This creates a searchable history of all appointments for reporting and analysis.

5. Slack Notifications

Your team receives instant Slack alerts about scheduling changes, helping everyone stay informed about appointment updates without constantly checking calendars.
