当承载广告的内容是非浏览器应用（通常为移动端）而非网站时，应包含该对象。一个竞价请求不得同时包含 Site、App、DOOH 对象中的多个。至少提供应用 ID 或 bundle 是有用的，但这并非严格要求。译稿校对中ENThis object should be included if the ad supported content is a non-browser application (typically in mobile) as opposed to a website. A bid request must not contain more than one of a Site, App or DOOH object. At a minimum, it is useful to provide an App ID or bundle, but this is not strictly required.

| inventorypartnerdomain | string | 在应用所有者与内容所有者存在库存共享安排时，用于库存授权的域名。该字段通常被授权爬虫（authorization crawlers）用于确认内容所有者的域名——内容所有者有权将应用内部分广告库存变现。内容所有者的域名应以 inventorypartnerdomain 形式列于应用所有者的 app-ads.txt 文件中；来自该 inventorypartnerdomain 的供给授权将发布在该域名根目录的 ads.txt 文件中。详见 ads.txt 1.1 规范。译稿校对中ENA domain to be used for inventory authorization in the case of inventory sharing arrangements between an app owner and content owner.

译注
译者注App 的三方互斥：2.6 中分发渠道为 Site ⊕ App ⊕ DOOH 三方互斥，同一请求至多包含其一；至少提供应用 ID 或 bundle 是有用的。译稿校对中
bundle 语义的扩展：2.6 将 bundle 从“平台专属应用标识符”明确为“应用商店 ID”，并纳入 CTV 场景（OTT/CTV 商店分配应用标识指南）；CTV 应用的标识形态与传统移动端（Android 包名/iOS 数字 ID）不同，接入 CTV 流量时应按指南核对取值格式。译稿校对中
id vs bundle：id 是交易平台专属标识，离开该平台即失效；bundle 是商店侧标识，跨链路稳定，是应用级匹配、归因与反欺诈的核心字段。译稿校对中
storeurl 与 app-ads.txt：storeurl 供买方核验应用真伪（IQG 2.1 要求）；与 app-ads.txt 授权核验配套使用，缺失 storeurl 会削弱供应链核验能力。译稿校对中
inventorypartnerdomain（应用侧）：与 Site 同名字段机制一致，差别在于授权声明位于应用所有者的 app-ads.txt（而非 ads.txt）；核验时应抓取对应应用的 app-ads.txt。译稿校对中
