API Reference

Get patient

Returns full details of a single patient by fingerprint. ### Multi-Clinic Visibility This endpoint succeeds if the API key's clinic has an active `CustomerClinicConnection` to the patient — **even if another clinic originally created the record**. Ownership of medical records within the patient is determined by `performed_by_clinic_fp` on each record. ### What This Returns Only the patient entity itself. Related medical records (SOAP, vaccines, medications, diagnostics) are fetched separately from their respective endpoints.

List patients

Returns a paginated list of patients accessible to the clinic associated with your API key. ### Access Model Patients in Vetigen are **global entities** — a single patient record may be shared across multiple clinics via `CustomerClinicConnection`. This endpoint returns patients that have an active connection to the caller's clinic, regardless of which clinic originally created the record. ### Pagination Use `page` and `page_size` query parameters. The response includes `has_more: true` when additional pages are available. ### Common Errors - `PATIENT.ACCESS_DENIED` — API key's clinic has no connection to the requested patients. - `AUTH.RATE_LIMITED` — see rate-limit headers.

List calendar events

Returns calendar events (appointments, surgeries, vaccinations, checkups, emergencies, sales) for the clinic associated with your API key. ### Timezone `start_at` and `end_at` are always UTC ISO 8601. When displaying to end users, convert to the clinic's configured timezone (returned in the `Patient` owner's locale settings, not on the event itself). ### Date Range Both `start_date` and `end_date` are optional. If omitted, the default window is **today through 30 days ahead**. Max allowed range is 90 days per request. ### Event Types & Status Machine - **Types:** `APPOINTMENT`, `SURGERY`, `VACCINATION`, `CHECKUP`, `EMERGENCY`, `SALE` - **Status flow:** `SCHEDULED → CHECKED_IN → IN_PROGRESS → PENDING_CHECKOUT → CLOSED` (or `CANCELLED`)
