# updateSetting

> Create or overwrite a named setting at the given scope. Provide exactly one value field in `SettingValueInput` (boolean, string, number, or stringArray) that matches the expected type for the setting code. Returns the stored setting on success. To clear a value and revert to the scope hierarchy default, use `deleteSetting` instead.
