  title: Velt Data (REST) API
  description: >-
    Server-side REST API for the Velt real-time collaboration platform. Velt is
    primarily a client SDK (React components and framework wrappers) that renders
    presence, live cursors, comments, notifications, huddles, recordings, and
    live selection inside applications. This Data API is the backend surface for
    that SDK: it lets servers read and write comments, users, organizations,
    folders, documents, notifications, and user groups, and manage workspace API
    keys, auth tokens, and webhook endpoints. All endpoints are HTTPS POST calls
    that take a JSON body wrapped in a top-level `data` object and are
    authenticated with the `x-velt-api-key` and `x-velt-auth-token` headers.
