  title: Google Tag Manager Safely Update a Tag
  summary: Read a tag for its fingerprint, then update it with optimistic concurrency.
  description: >-
    A conflict-safe edit flow for a single tag. The workflow gets the tag to
    read its current fingerprint and then updates the tag, passing that
    fingerprint as the concurrency guard so the write is rejected if the tag was
    changed underneath. Each step spells out its request inline, including the
    inline bearer authorization, so the flow can be read and executed without
    opening the underlying OpenAPI description.
