  title: Webflow Add Item to an Existing Collection
  summary: Resolve a site, find an existing Collection by slug, then create a new item in it.
  description: >-
    A discovery-driven content flow. It lists the accessible sites, lists the
    Collections on the chosen site, branches to confirm a Collection matching
    the requested slug exists, and then creates a new draft item in that
    Collection. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
