Ask to move or cancel an appointment

Move or cancel one of the patient's appointments. Xona texts the patient a link to a page that shows the exact change. When they press its button (or type the code from the text on book.xonark.com/code) the practice's schedule changes, or, at a practice that confirms changes itself, the practice receives the request. Calling again with the same arguments returns the result, read live from the practice's schedule.
