# 获取最新的 SSL 证书请求

> GET /custom-domain/{pk}/certificate-request/

在 **Management API** 主机（`api.scanova.io`）上获取某个域名最新的 SSL 证书签名请求（CSR），使用您的原始 Management API 密钥进行身份验证。

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

<Warning>
  仅限企业版。需要 `CUSTOM_DOMAIN_CUSTOM_SSL` 配额，该配额需人工授予——没有任何自助套餐包含此配额。
</Warning>

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

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

<ResponseExample>
  ```json 200 theme={null}
  {
    "id": 5,
    "organization": "Example Inc",
    "organizational_unit": "IT",
    "country": "US",
    "state": "CA",
    "locality": "San Francisco",
    "email": "ssl@example.com",
    "csr": "-----BEGIN CERTIFICATE REQUEST-----\nMIIC...\n-----END CERTIFICATE REQUEST-----",
    "created": "2026-09-01T09:00:00Z"
  }
  ```
</ResponseExample>

如果尚未创建 CSR，则返回 `null`。这使客户端可以在不自行跟踪 CSR 状态的情况下恢复正在进行的自带证书（bring-your-own-certificate）流程。如果账户缺少 `CUSTOM_DOMAIN_CUSTOM_SSL` 配额，则返回 `403`；如果 `pk` 不是该账户拥有的域名，则返回 `404`。

      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.
