Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

appointo

appointo_cancel_booking

WRITE: cancel a booking, or only some of its customers. The slot is freed and Appointo may notify the customers; whether a Shopify order is refunded is not controlled by this call. Cannot be undone through this server (create a new booking instead). The docs cap this at 100 requests per day. PUT /bookings/cancel.

appointo_create_booking

WRITE: create a booking for a customer on an appointment (bookable service) at a time slot. This is a real booking: Appointo may email the customer a confirmation and reserve the slot; the booking can later be cancelled with appointo_cancel_booking. Check appointo_get_availability first. Not idempotent: calling twice creates two bookings. The docs cap this at 100 requests per day. POST /bookings.

appointo_get_availability

The free time slots of one appointment (bookable service) from start_date, optionally to end_date. Use it before creating or rescheduling a booking. GET /appointments/{appointment_id}/calendar_availability.

appointo_list_appointments

List appointments, i.e. the bookable services/variants, with name, price, currency and configuration. Filter by product or fetch one by id. These are the services customers book, not the bookings themselves (use appointo_list_bookings for those). GET /appointments.

appointo_list_bookings

List bookings with time, product, duration, quantity, price and the customers (name, email, phone, address). Filter upcoming/past or search; pass booking_id for one booking. The customers' cancel/reschedule link ids are never returned. GET /bookings.

appointo_list_cancelled_bookings

List cancelled bookings, same shape as appointo_list_bookings. GET /bookings/cancelled_bookings.

appointo_list_products

List the Shopify products that are set up as bookable in Appointo: name, appointment type, whether the widget is shown, and each product's appointments (the bookable variants/services with price, currency and id). Use an appointment id for availability and bookings. GET /products.

appointo_list_subscription_contracts

List the recurring booking subscription contracts (customers who subscribed to repeat appointments). Search by product, variant, order number or customer name. The API documents no paging for this list. GET /appointment_subscriptions.

appointo_reschedule_booking

WRITE: move a booking (or only some of its customers) to a new time slot. Appointo may notify the customers of the change. override=true forces the booking into the slot even if it is unavailable or full, so leave it off unless the user explicitly asked for it. The docs cap this at 100 requests per day. PUT /bookings/reschedule.

appointo_update_booking_buffers

WRITE: set the start and/or end buffer time (minutes blocked before/after) of one booking. At least one value is required. The docs cap this at 100 requests per day. PUT /bookings/{booking_id}.
