Field facts

Path: app.content.channel.domain, dooh.content.channel.domain, site.content.channel.domain
Object: Channel
Type: string
Requirement: Optional
Added: OpenRTB 2.6-202204
Spec section: 3.2.24

Example

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

{
  "id": "req-1",
  "app": {
    "content": {
      "channel": {
        "domain": "northwinddrama.example"
      }
    }
  }
}

Common mistakes

Reusing the network's domain for every channel, which makes channel-level targeting impossible when the channels have their own sites.
