  title: SuperViz REST API
  description: >-
    Representative OpenAPI description of the SuperViz server-side REST API.


    SuperViz is SDK-first: real-time collaboration and communication features
    (presence, realtime data channels, video huddle, contextual comments, mouse
    pointers) are implemented in the browser with the `@superviz/sdk` and
    `@superviz/react-sdk` client libraries, initialized with a developer key.


    This REST API at `https://api.superviz.com` is the supporting server-side
    surface. It lets a backend read presence and participants, introspect
    channels, publish events into realtime channels, read room participants and
    contextual comments, and retrieve video meeting statistics. All REST
    requests authenticate with a Client ID and Secret Key issued from
    Dashboard > Developer > Keys, sent as the `client_id` and `secret` request
    headers.


    Endpoints, paths, and field shapes here are modeled from the public SuperViz
    documentation at https://docs.superviz.com and are intended as a faithful,
    representative specification rather than an exhaustive dump of every field.
