nookal

nookal_get_availability

Get the free appointment slots per date between two dates (max 60 days, Nookal's limit), optionally for given locations, practitioners and a service. Each slot has its date, start time (24h, clinic local time), provider id and location id. Read-only: it does not book anything. Nookal GraphQL: availabilities.

nookal_get_client

Get one client (patient) by id: name, date of birth, contact details, addresses, alerts, allergies, notes, occupation, referring doctor and their treatment cases; optionally a summary of their invoices (totals and balances). Health-fund, pension and online-booking codes are not returned. Nookal GraphQL: clients.

nookal_list_appointments

List appointments (date, start/end time, status, type, client, practitioner, case, location, arrived / did-not-arrive flags, notes), filtered by date range, location, client, practitioner, type and status. Dates are clinic local. Nookal GraphQL: appointments.

nookal_list_cases

List treatment cases (id, client, title, start and referral dates, referrer, primary practitioner, notes), filtered by client, case or practitioner. Nookal GraphQL: cases.

nookal_list_classes

List the class types offered (id, name, category, duration, price, location, online-booking settings) — the class definitions, not individual sessions. Nookal GraphQL: classes.

nookal_list_invoices

List invoices with their line items and payments (number, client, case, location, practitioner, date, subtotal, tax, total, paid, balance), filtered by location, invoice id or creation date. For one client's invoices use get_client with include_invoices. Nookal GraphQL: invoices.

nookal_list_locations

List the clinic's locations (id, name, address, time zone, active). Location ids are needed by most other tools. Only the locations your API client was granted are returned. Nookal GraphQL: locations.

nookal_list_payments

List payments received against invoices (method, amount, date, reference, invoice, client, location), filtered by invoice or payment date. Nookal GraphQL: payments.

nookal_list_services

List the appointment types / services offered (id, name, category, duration in minutes, price, location, online-booking settings). Use a service id in get_availability. Nookal GraphQL: services.

nookal_list_staff

List staff members and practitioners (id, name, title, speciality, email, location ids, whether they are a provider / bookable online / active). Use the staff ids as provider_ids in list_appointments and staff_ids in get_availability. Nookal GraphQL: staff.

nookal_search_clients

Find clients (patients) by name, date of birth, mobile, email or id. Returns id, name, date of birth, location, active/deceased flags and contact details. With partial_match, names match on their first letters (e.g. 'Sm' finds Smith). Nookal GraphQL: clients.
