Auto approve new bookings ?

Hello, I was wondering if there is any way to automatically approve news appointments / bookings ? because we are using the Google calendar sync and therefore our calendars are always up to date…meaning that we don’t need to check if anyone has already booked or not…(same calendar is used wether someone called or asked by email for an appointment)

instead of clicking on the email validation, maybe I should just say in the first email that the appointment is booked as asked by the user…?

Thanks.
