  title: Sesame HR Public Absences and Leave API
  description: The Sesame Public API (v3) exposes the Sesame HR platform - employees, time tracking (check-in / check-out), work hours, shifts and scheduling, vacations, absences and leave, departments, offices, and the organization chart - over a documented REST interface. All requests are authenticated with a Bearer API token generated in the Sesame admin panel (Settings > Integrations > API at app.sesametime.com). The base host is region-specific (api-{region}.sesametime.com, default region eu1) and every path is prefixed with /core/v3. This document models the subset of the ~500-endpoint API most relevant to HRIS, time-tracking, and workforce-management use cases; endpoint paths and the Bearer scheme are taken from the official documentation, while some request/response field shapes are modeled generically where the public docs do not publish a full schema.
