Cancel an appointment using this endpoint. Once canceled, appointments will have a noShow attribute. This attribute may be updated, but it isn't possible to un-cancel the appointment.

Cancel as an Admin

📘

?admin=true

By default appointments are canceled as a client. Canceling an appointment as an admin allows setting the "noShow" field and disables cancellation rules. To cancel as an admin pass the query parameter admin=true.

No Email

Skip sending the cancellation e-mail and SMS by canceling the appointment with the noEmail=true query parameter.
