ezyVet Animals (Patients) API

openapi: 3.0.3
info:
  title: ezyVet API
  description: >-
    The ezyVet API is a RESTful interface to ezyVet, cloud-based veterinary
    practice information management software (PIMS). ezyVet was founded in New
    Zealand in 2006 and acquired by IDEXX Laboratories in June 2021, alongside
    IDEXX's Cornerstone and Neo PIMS (the acquisition also included Vet Radar).

    The full API spans roughly 216 endpoints across animals/patients,
    contacts/clients, appointments, consultations, invoices, products, and
    diagnostics. Access is partner-gated: a developer must apply for an
    integration and receive an approved partner_id plus client_id/client_secret,
    then obtain a bearer token via the OAuth 2.0 Client Credentials grant. Tokens
    have a 12-hour TTL.

    GROUNDING NOTE: The OAuth token endpoint, the /v1/contact CRUD endpoints, the
    Standard Diagnostic Integration, and the base/rate-limit behavior below are
    confirmed from ezyVet's public developer documentation (developers.ezyvet.com).
    The remaining resource paths (animal, appointment, consult, invoice, product,
    diagnostic, prescription, vaccination and their reference resources) are
    MODELED on ezyVet's documented /v1/{resource} REST pattern and published
    resource categories - operationId or path names may differ from the exact
    ezyVet catalog. Consult the partner Postman collection for authoritative
    request/response shapes.
