Right now once booking is made customer receives the email with Cancel and Reschedule link. Once the link is hit it cancels the appointment and then shows you availability to reschedule. Instead of clicking on the email link and reschedule this endpoint will allow us to reschedule existing booking via api.
The resource_id parameter is required and could be any resource (in the same project, in a different project or in no project). Please note that the booking id will change in the response.
