It is common to set a time limit for customers who book with you to cancel an upcoming appointment. This avoids last minute cancellations and empty slots in your schedule that could have been used by other clients.
Let's see how to set the maximum number of hours before a booking so that customers can cancel the appointment.
Log in to TuCalendi with your username and password. Go to the "Calendars" option:

Locate the event for which you want to set the limit of hours for customers to cancel the scheduled appointment.
In the horizontal menu, all the event configuration options appear.
Click on "Advanced".

In the "Cancellation" field, you only have to enter the limit in hours up to which a meeting with you can be cancelled.
Once you have entered it, just click on the "Save" button to activate the cancellation limit.
Remember to create the workflows to associate the cancellation template with the events.
