  title: Storyblok Tag-Driven Content Sync
  summary: Discover tags, list the stories carrying a chosen tag, then fetch the full content of the first match.
  description: >-
    A read-side delivery flow for syndicating tagged content. The space's tags
    are first discovered, the stories carrying a chosen tag are listed, and the
    full content of the first matching story is then fetched by slug. Storyblok
    exposes tags as a read-only derived list on the Content Delivery API — tags
    are created implicitly by attaching tag_list values to stories rather than
    through a dedicated tag-write endpoint — so this flow consumes tags rather
    than authoring them. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
