## Editor interface

An editor interface is a singleton resource of a content type, that means that there can only be one editor interface per content type at a time. If a content type is not activated yet, the API will return a 404 response. An editor interface is created automatically on the first activation of a content type and updated when a content type field is added, removed or renamed.
