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

wubook

wubook_check_in

WRITE: check in the guests of a reservation in ZaK. Applies to every guest of the reservation unless room_customer_ids is given. POST /kp/reservations/do_checkin.

wubook_check_out

WRITE: check out the guests of a reservation in ZaK. Applies to every guest of the reservation unless room_customer_ids is given. POST /kp/reservations/do_checkout.

wubook_create_reservation

WRITE: create a reservation in ZaK for one guest. Give rooms (room type and optionally the physical room id, with price and currency) and/or products (product id with price and currency). Set assign_rooms to let ZaK pick the physical rooms. This books inventory and is NOT idempotent: calling it twice creates two reservations, so check wubook_get_room_availability first and do not retry on an error without looking the reservation up. POST /kp/reservations/new.

wubook_get_customer

One guest record by customer id (from a reservation's booker or room customers): name, country, address, contact, birth data, billing info. Personal data. Identity documents (type, number, expiry) are left out unless include_documents is true. POST /kp/customers/fetch_one.

wubook_get_inventory_symbols

The meaning of the short keys in prices and restrictions (p price, a availability, m MinStay, M MaxStay, c closure, ...). POST /kp/inventory/fetch_symbols.

wubook_get_rate_values

Daily prices, availability and restrictions of one rate, starting at a date: for each product id a list with one object per day (p price, a availability, m/M min/max stay, c closed, ...; see wubook_get_inventory_symbols). POST /kp/inventory/fetch_rate_values.

wubook_get_reservation

One reservation by id or by reservation code (XY-0001): status, booker customer id, origin channel, board, dates, price split (rooms, extras, meals), payment, taxes and rooms with occupancy and customer ids. POST /kp/reservations/fetch_one_reservation.

wubook_get_room_availability

Availability for a stay: for each room type id, the number of rooms available and the ids of the available physical rooms. The availability count can be lower than the number of listed physical rooms when a reservation has no physical room assigned yet; use the availability count when assessing bookable capacity. POST /kp/inventory/fetch_rooms_availability.

wubook_list_extras

List the extras the property sells (id, name, price, VAT percentage, cost, tags). POST /kp/property/fetch_extras.

wubook_list_meal_boards

List the meal rules and meal prices per board type (fb, hb, bb, ai) for adults, teens, children and babies. POST /kp/property/fetch_meals_board.

wubook_list_products

List the products (a room type sold on a board basis: id, room type id, name, default price, occupancy). Product ids are the keys of prices and availability. POST /kp/property/fetch_products.

wubook_list_rates

List the rates of the property (id, name, board, currency, standard flag). Use a rate id for prices and restrictions. POST /kp/property/fetch_rates.

wubook_list_reservations

List reservations, optionally filtered by creation, arrival or departure date ranges (inclusive). Newest first is not guaranteed; page with offset. Returns the page plus next_offset (null when the last page was reached). POST /kp/reservations/fetch_reservations.

wubook_list_room_types

List the room types (id, name, short name, default price, default occupancy). POST /kp/property/fetch_room_types.

wubook_list_rooms

List the physical rooms of the property (id, room type id, name, tags). POST /kp/property/fetch_rooms.

wubook_list_todays_reservations

Reservations of the property for today (arrivals, departures and stays in house). POST /kp/reservations/fetch_today_reservations.

wubook_undo_check_in

WRITE: revert the check-in of a reservation in ZaK. POST /kp/reservations/undo_checkin.

wubook_undo_check_out

WRITE: revert the check-out of a reservation in ZaK. POST /kp/reservations/undo_checkout.

wubook_update_inventory

WRITE: overwrite daily prices, availability and stay restrictions of one rate. `products` maps a product id to a list of day objects; the first object is the day `from`, the next the following day, and so on. Only the fields you send per day change. Changes can be pushed to connected channels (OTAs) and affect live bookings, so confirm the values with the user first. POST /kp/inventory/write.
