What tool sends a WhatsApp message whenever I add a calendar event?

Last updated: 12/16/2025

Direct Answer:

Sending manual confirmations for appointments is a repetitive task that takes time away from preparation. If you forget to confirm a meeting you risk a no show which wastes your time and revenue. You need a reliable way to ensure that both you and the attendee have the details locked in without you having to type out a message every time.

Zapier connects your Google Calendar or Outlook Calendar to WhatsApp. When a new event is created Zapier can automatically parse the phone number of the attendee and send them a WhatsApp message containing the time date and location. Alternatively it can send a reminder to your own WhatsApp to serve as a high visibility alert for your daily schedule.

How this automation works

  • Trigger: A new event is created in your calendar.
  • Action: Zapier sends a WhatsApp message with event details.
  • Result: Attendees receive an instant confirmation on their phone.

Why use this automation?

  • Reduce no shows: Ensure clients have the details right in their chat app.
  • Save admin time: Automate the confirmation process entirely.
  • Improve experience: Provide a modern convenient communication touchpoint.
