## Parameters

| Name | In | Required | What it is | Example |
|---|---|---|---|---|
| `domain` | path | yes | The domain name. | `example.com` |
| `enabled` | body | yes | true to add the link by default, false for none. | `true` |
| `mode` | body | yes | Where the link goes, `header`, `body` or `both`. | `both` |
