Can the AI find an available slot for a specific service next Friday?

Yes. Upon providing the location and service ID along with the desired date, your agent invokes `get_availability`. The connector reads Picktime's master block array, isolating the open time windows seamlessly against existing rules (like business hours and buffers).

If a customer cancels on the phone, can the AI remove their booking?

Absolutely. Just provide the booking ID to the agent and it will utilize the `cancel_booking` function. Picktime will release the blocked slot immediately back to the customer-facing booking page.

Can I grab all upcoming appointments for a specific staff member?

Yes, by matching the staff member's ID from `list_staff` with the broader fetch generated by `list_bookings`. Alternatively, your agent can sort and filter the returned array natively in its reasoning stream, showing you only Dr. Silva's schedule.
