A convincing conversation is not a confirmed booking. The integration must prove the appointment action succeeded.
Define the allowed actions
Document which appointment types, practitioners, locations, and time windows may be offered. Decide what requires staff review and what should become a callback request.
Design for failure
If the booking system is unavailable or returns an uncertain result, the receptionist should not claim success. It should explain the next step, capture the minimum useful details, and route the request to the clinic.
Test real scenarios
Verify new bookings, rescheduling, cancellation policy, duplicate callers, no availability, ambiguous names, and provider downtime before enabling live patient calls.
