  title: Fastly Purging API
  description: >-
    The Fastly Purging API enables developers to instantly remove cached content
    from Fastly's edge network so it can be refreshed from origin servers. It
    supports single URL purges, surrogate key purges for invalidating groups of
    related objects, and purge-all operations to clear an entire service cache.
    Surrogate key and URL purges are separately limited to an average of 100,000
    purges per hour per customer and are not counted against the general API rate
    limit.

      summary: Purge a URL
      description: >-
        Instantly purges a single URL from Fastly's edge cache. The cached URL
        should be the full URL of the object to purge. Supports soft purge via
        the Fastly-Soft-Purge header, which marks the object as stale rather
        than removing it immediately.
