# Apply a site config document

> Applies every path the document names in one transaction; a path it leaves out stays as it is. A currency change that relabels lesson type prices answers 409, and so does a document that leaves out an extra site with a live custom domain (`errors` names `domainBound:<host>`). Needs a `site:write` token.
