# 创建用户设计模板

> POST /qr-assets/design-template/

在 **Management API** 主机（`api.scanova.io`）上为某个 QR 分类或表单保存一个新的设计模板，使用您的原始 Management API 密钥进行身份验证。

```
POST https://api.scanova.io/qr-assets/design-template/
Authorization: 401f7ac837da42b97f613d789819ff93537bee6a
```

<ParamField body="name" type="string" required>
  模板名称，最多 150 个字符。
</ParamField>

<ParamField body="resource_type" type="string" default="qr_category">
  `qr_category` 或 `form`。
</ParamField>

<ParamField body="category" type="integer">
  此模板所属的 `QRCategory` id。当 `resource_type` 为 `qr_category` 时**必填**；当 `resource_type` 为 `form` 时**必须省略**。
</ParamField>

<ParamField body="design_info" type="object">
  任意 JSON 设计数据。
</ParamField>

<ParamField body="gradient_type" type="string">
  渐变样式，例如 `linear`。
</ParamField>

<ParamField body="color_palette" type="string">
  调色板，通常以 JSON 字符串编码。
</ParamField>

<ParamField body="font_styles" type="string">
  字体样式数据。
</ParamField>

<ParamField body="is_template" type="boolean" default="false">
  将此记录标记为可重复使用的模板，而非一次性保存。
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X POST "https://api.scanova.io/qr-assets/design-template/" \
    -H "Authorization: 401f7ac837da42b97f613d789819ff93537bee6a" \
    -H "Content-Type: application/json" \
    -d '{
      "name": "Blue Gradient",
      "resource_type": "qr_category",
      "category": 3,
      "design_info": { "bg": "#0033ff" },
      "gradient_type": "linear",
      "is_template": true
    }'
  ```
</RequestExample>

<ResponseExample>
  ```json 201 theme={null}
  {
    "id": 9,
    "name": "Blue Gradient",
    "resource_type": "qr_category",
    "category": 3,
    "design_info": { "bg": "#0033ff" },
    "gradient_type": "linear",
    "color_palette": null,
    "font_styles": null,
    "is_template": true,
    "info": null,
    "template_id": null
  }
  ```
</ResponseExample>

## `resource_type` 与 `category` 的配对规则

`resource_type=qr_category` 时 `category` 为必填，`resource_type=form` 时则禁止提供——序列化器和数据库检查约束都强制执行此规则，因此不会出现不一致。如果搞反了，会返回 `400`，附带 `{"category": "This field is required for qr_category templates."}` 或相反的错误信息。

      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.
