# 删除自定义域名

> DELETE /custom-domain/{pk}/

在 **Management API** 主机（`api.scanova.io`）上将自定义域名从账户断开连接，使用您的原始 Management API 密钥进行身份验证。

```
DELETE https://api.scanova.io/custom-domain/{pk}/
Authorization: 401f7ac837da42b97f613d789819ff93537bee6a
```

<Note>
  需要 `CUSTOM_DOMAIN_CAN_DELETE` 权限。
</Note>

<ParamField path="pk" type="integer" required>
  域名的 `id`。
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X DELETE "https://api.scanova.io/custom-domain/42/" \
    -H "Authorization: 401f7ac837da42b97f613d789819ff93537bee6a"
  ```
</RequestExample>

调用成功会返回 `204 No Content`。

## 必须先解除与 QR 码的关联

如果该域名仍与任何 QR 码相关联（包括已放入回收站的），此调用会返回 `400`，并附带 `{"error": ["This domain is linked to QR Code(s)... Delete permanently the QR Code(s) first..."]}`，而不会删除域名。请先永久删除（而非仅放入回收站）相关联的 QR 码，然后重试。如果 `pk` 不是该账户拥有的域名，则返回 `404`。

    The complete Scanova Management API — every endpoint available at

    used to authenticate against it. Every path and request/response shape below

      description: >-
        Send your Management API key as the raw value of the Authorization
        header — no "Bearer " or "Token " prefix, and no other characters.
        Example: `Authorization: 401f7ac837da42b97f613d789819ff93537bee6a`. A
        header containing more than one space-separated part is rejected
        outright. Requests also require the request's Host header to be the
        management API host (e.g. api.scanova.io) — the same key sent to the
        regular API host will not authenticate.
