What This Workflow Does

This automation solves the problem of constantly checking multiple platforms for booking updates. Professionals using Cal.com or Calendly often miss important appointment changes buried in email notifications or have to manually check their calendars throughout the day.

The workflow monitors both scheduling platforms in real-time, then sends beautifully formatted WhatsApp messages for every booking activity. It transforms raw booking data into mobile-friendly notifications with all relevant details clearly presented.

How It Works

1. Booking Detection

The workflow continuously monitors both Cal.com and Calendly for new, changed, or canceled appointments through their API connections.

2. Data Aggregation

Booking details from both platforms are standardized into a common format, ensuring consistent notifications regardless of which service was used.

3. AI Message Formatting

Google Gemini transforms the raw booking data into human-readable WhatsApp messages with proper spacing, emojis, and emphasis on key details.

4. Instant Notification

The formatted message is immediately sent via WhatsApp Business API to your specified number, typically arriving within seconds of the booking activity.

Pro tip: For teams, you can modify the workflow to notify multiple WhatsApp numbers when bookings involve specific team members or meeting types.
