Patient Appointment Booking Sequence
How a patient books a doctor's appointment online: checking free slots, holding one, paying the consultation fee and getting a confirmation.

What this diagram shows
- Slot is held briefly so two patients can't book the same time
- Payment happens before the booking is confirmed
- Doctor and patient are both notified at the end
Prompt used
Sequence for a patient booking a doctor appointment: the patient app asks the appointment service for free slots, the patient picks one and it is held for 5 minutes, the payment service charges the consultation fee through a payment gateway, then the appointment is confirmed and the notification service sends SMS to the patient and an alert to the doctor.
