  title: Webflow Deploy Custom Code to a Site
  summary: Resolve a site, register a hosted script, then apply it to the site's header.
  description: >-
    A custom-code deployment flow. It resolves the target site, registers an
    externally hosted script against the site so it becomes available, and then
    applies that registered script to the site by referencing its id and
    version in the header. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI
    description.
