  title: Twilio Create a Video Room
  summary: Create a Twilio Video room, then fetch it so a client can join.
  description: >-
    The canonical Twilio Video onboarding pattern. The workflow creates a new
    video room via the Twilio Video REST API, choosing the room type and
    participant limits, and captures the returned room SID and unique name. It
    then fetches the same room by SID to confirm it is in progress and to read
    the details a client SDK needs to connect, such as the room SID, unique
    name, type, and status. With an in-progress room confirmed, a client can
    mint an access token scoped to that room and join. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
