# Add a domain

> Adds a domain or URL to a brand of this project. It counts as the brand's from today; citations already recorded keep their labels. A domain the project already holds, including one recorded from citations, moves to this brand, and previousBrandId names the brand it left. A spelling that cannot be tracked returns 400 with the reason. A brand outside this project returns 404. Requires the setup.write scope.
