  title: YouTube Upload and Update a Caption Track
  summary: Upload a draft caption track for a video, then publish it by updating its draft status.
  description: >-
    A two-stage captioning flow. It uploads a caption track for a video as a
    draft, captures the new caption id, and then updates the caption resource to
    clear the draft flag so the track becomes visible. Note the YouTube captions
    endpoints also support resumable media upload of the caption file; this
    workflow handles the JSON caption resource the OpenAPI description models.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
