| Attribute | Type | Description |
|---|---|---|
| id | string | 用户的标识符。译稿校对中ENThe identifier for the user. |
| atype | integer | 该 ID 所属的用户代理（user agent）类型。强烈建议设置本字段——许多 DSP 将应用原生 ID 与浏览器 ID 分开处理，且 ID 解析需要类型取值。参见 AdCOM 1.0 列表：代理类型（List: Agent Types）。译稿校对中ENType of user agent the ID is from. It is highly recommended to set this, as many DSPs separate app-native IDs from browser-based IDs and require a type value for ID resolution. Refer to List: Agent Types in AdCOM 1.0枚举 Agent Types · 4 个值1An ID which is tied to a specific web browser or device (cookie-based, probabilistic, or other). 2In-app impressions, which will typically contain a type of device ID (or rather, the privacy-compliant versions of device IDs). 3A person-based ID, i.e., that is the same across devices. 500+Vendor-specific codes. |
| ext | object | 供供应商对本对象进行专属扩展（vendor specific extensions）的占位对象。译稿校对中ENPlaceholder for vendor specific extensions to this object. |
译注
译者注atype 的必要性：省略 atype 会显著降低 ID 的可用性——DSP 无法区分应用原生 ID（如 IDFA/GAID）与浏览器侧 ID（如 UID2），可能直接丢弃该 ID；传递 UID 时应始终配套 atype。译稿校对中
