## 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.

[Update the editor interface](/references/content-management-api/editor-interface/update-the-editor-interface)

You can use this endpoint to update an existing editor interface. You will need to specify its last version with `X-Contentful-Version`.
