### Request Body Parameters

| Argument | Type | Description |
|  --- | --- | --- |
| description | String | (Optional) The readable description you see in the UI for the attribute. |
| options | array | (Optional) Array of objects representing the options of the list, with `value` as the key and the option as the value. At least two options are required. `data_type` must be `options`. |
| archived | Boolean | (Optional) Whether the attribute is to be archived or not. |
| messenger_writable | Boolean | (Optional). When set to `false`, the attribute will not be writable by the Messenger. Default value is `true`. |


Updating the data type is not possible
It is currently a dangerous action to execute changing a data attribute's type via the API. You will need to update the type via the UI instead.

### Response

This will return a [Data Attribute Model](/docs/references/2.0/rest-api/data-attributes/data-attribute-model) showing the details of your updated attribute.
