Reschedule appointment
Move an appointment to a new date and time, or to another calendar.
MCP tool acuity_scheduling_write → reschedule_appointment
write Confirm
Moves one appointment to the new datetime, and to another calendar if you pass one. Acuity returns an error if the appointment is canceled, is a class series, or the new time is not an open slot. Acuity emails and texts the client about the new time unless send_notification is false. By default you confirm each call; you can switch that off for this tool.
