Field facts

Path: app.inventorypartnerdomain
Object: App
Type: string
Requirement: Optional
Added: OpenRTB 2.6-202211
Spec section: 3.2.14

How it is used

Common in CTV, where a channel or content partner sells some of the ad breaks inside a distributor's app. The app owner names the partner in its app-ads.txt with the INVENTORYPARTNERDOMAIN variable from ads.txt 1.1, and the partner publishes the sellers it authorizes in the ads.txt at the root of its own domain. Before 2.6-202211 the value lived in app.ext.inventorypartnerdomain.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "app": {
    "inventorypartnerdomain": "northwindtv.example"
  }
}

Common mistakes

Setting it when the app owner sells its own inventory. Leave it out unless a sharing arrangement exists.
Naming a partner that the app owner's app-ads.txt does not list, which makes the partner's supply look unauthorized.
