To give the option to cancel the booked appointment to your customer you can add a cancellation link to the confirmation e-mail by going to Company > Settings > E-Mail / SMS templates.
The cancellation link is already included in the confirmation e-mails by default. The placeholder for the cancellation link is CANCELLINK and can be added in every template by adding the following HTML-Code: <a href="CANCELLINK">here</a>.
If you want to you can set the field reason for cancellation as a mandatory field by using CANCELLINKMANDATORY as a placeholder instead.
After a successful booking the booker will now receive a confirmation e-mail that includes the cancellation link.
As soon as your customer klicks on here a new window with the cancellation will open.
Your customer now has the option to communicate the reason why they want to cancel the appointment.
