A new appointment is scheduled
The appointment is confirmed
The appointment is canceled
The client or prospect attends the appointment
The client or prospect does not attend the appointment (No-Show)
The appointment is determined to be invalid

9. Improve the filter by adding 'Has Tag'
When you select a tag using the "Has Tag" filter, this workflow automatically activates once a customer linked to that tag updates their appointment status.

When you choose a particular user's calendar with the "In Calendar" filter, this workflow will automatically trigger whenever there is a change in the appointment status of any customer linked to that specific calendar.
