Send only what you want to change; the rest stays as it is. The answer is the domain's settings afterwards.

## Parameters

| Name | In | Required | What it is | Example |
|---|---|---|---|---|
| `domain` | path | yes | The domain name. | `example.com` |
| `mail_enabled` | body | no | Accept mail for the domain. | `true` |
| `dns_managed` | body | no | Whether its DNS zone is kept here. Only the setting changes; no zone is created or removed. |  |
| `active` | body | no | false turns the whole domain off, as Disable a domain does; true turns it back on. |  |

## Good to know

- A domain that isn't listed answers 404.
