# Returns a list of AppointmentTasks (V1) based on filter criteria

**Query shape:** Prefer a **narrow** filter—combine `appointment.id` or `id` with other scoping keys where possible. A very wide query with no scoping can **408** (timeout) on large tenants; retry with a smaller window or use cursor pagination (`lastId`—see parameter descriptions).
**Empty results:** **200** with `data: []` means no appointment tasks matched; it does not indicate invalid filter values.
**responseFields:** Use only names allowed on this operation (see the `responseFields` parameter). Use `ALL` or the documented flat field list.
**Pagination:** The `page` query parameter is deprecated; **`lastId`** style pagination is preferred. See the Public API pagination documentation.
