Cliniko Invoices API

  title: Cliniko Appointment Types Invoices API
  description: 'Cliniko is practice management software for allied health practices and clinics. This is a representative subset of the public Cliniko REST API, grounded in the official documentation at https://docs.api.cliniko.com and the redguava/cliniko-api GitHub repository. It is not the complete surface - Cliniko documents 50+ resources (appointment types, attendees, availability blocks, billable items, bookings, businesses, communications, concession types, contacts, group appointments, individual appointments, invoices, invoice items, medical alerts, patients, patient attachments, patient cases, patient forms, practitioners, products, recalls, referral sources, services, settings, stock adjustments, taxes, treatment notes, users, and more).

    Base URL is region-sharded. The shard is the suffix on your API key (for example a key ending `-uk1` is served from `https://api.uk1.cliniko.com`); keys with no suffix belong to the `au1` shard. All paths are prefixed with `/v1`.

    Authentication is HTTP Basic: the API key is the username and the password is empty (`-u API_KEY:`). Every request MUST also send an `Accept: application/json` header and a `User-Agent` header of the form `APP_VENDOR_NAME (APP_VENDOR_EMAIL)` containing a valid contact email, or requests may be automatically blocked. Requests are rate limited to 200 per minute per user; a `429` response includes an `X-RateLimit-Reset` header with a UNIX timestamp.

    Modeled note - the field sets below are drawn from the documented example responses; some optional attributes may be omitted, and request-body schemas are representative rather than exhaustive.'
