Ordered by `created_at` descending (most recently **booked** first) by default so a polling integration that reads only the first page catches every new booking. Pass `?sort=starts_at` to order by when the session is **scheduled** instead (an agenda view). `from`/`to` always filter on `starts_at`, whichever sort is used. Filter by status, tutor, student, or date range. Supports limit/offset and cursor pagination. Common status values: completed, scheduled, cancelled, pending, time_change_requested, disputed. ## OpenAPI ````yaml /openapi.json get /v1/sessions openapi: 3.1.0 info: title: ClassQuill Public API description: >- REST API for ClassQuill tutoring organisations.
