  title: Fastly Bulk Purge Surrogate Keys
  summary: Confirm a service exists, then purge up to 256 surrogate keys in one request.
  description: >-
    Invalidates many cache tags at once. The workflow confirms the target
    service exists and then submits a batch of surrogate keys to be purged in a
    single call, returning a map of each key to its purge status identifier.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
