Field facts

Path: site.kwarray
Object: Site
Type: string array
Requirement: Optional
Added: OpenRTB 2.6-202204
Spec section: 3.2.13

Example

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

{
  "id": "req-1",
  "site": {
    "kwarray": [
      "local news",
      "city council",
      "transit"
    ]
  }
}

Common mistakes

Putting every keyword into a single comma-separated element, which brings back the parsing problem the array was meant to remove.
Sending kwarray alongside keywords. The validator reports the pair as mutually exclusive.
