# 类别
该 `target_category` source 旨在根据 Target 的 taxonomy node ID 检索 Target 类别页面。该 source 支持本地化功能，并允许你浏览 Target 的产品类别。

将结果适配到特定商店、履约类型和配送地点。
| 参数 | 说明 | 类型 |
| ------------------ | ---------------------------------------------------------------- | --- |
| `fulfillment_type` | 设置履约类型。可用值为：pickup、shipping、shop\_in\_store、same\_day\_delivery。 | 字符串 |

## 了解 Target 的 node ID
Target 的类别系统使用 node ID 来标识特定类别。这些 node ID 是 Target taxonomy 系统中的唯一标识符。
### 示例 node ID
node ID 可在类别页面 URL 中找到。它是 URL 中格式为 `N-<5 个符号>` 的部分。下面是一些示例类别 URL 及其对应的 node ID：
1. PlayStation 5 控制器： `owq2q`
* 完整 URL：
2. PlayStation 5 配件： `lbxgt`
* 完整 URL：
3. PlayStation 5： `hj96d`
* 完整 URL：
### node ID 格式
使用 `target_category` source 时，你只需要提供 node ID，而不需要提供 `N-` 前缀。API 会自动将 URL 格式化为正确形式。
