  title: Holistics API
  description: >-
    REST API for the Holistics business intelligence and self-service analytics
    platform. Covers the Data Pipeline API (execute data imports/transforms and
    poll ETL jobs), report and dataset query APIs, and asynchronous data export
    (CSV/JSON/XLSX). All requests authenticate with a per-user API key passed in
    the X-Holistics-Key header. Regional hosts are secure.holistics.io (APAC),
    us.holistics.io (US), and eu.holistics.io (EU).
