Field facts

Path: app.content.kwarray, dooh.content.kwarray, site.content.kwarray
Object: Content
Type: string array
Requirement: Optional
Added: OpenRTB 2.6-202204
Spec section: 3.2.16

How it is used

The spec text for 2.6-202210 to 2.6-202303 misspelled the field as kwarry in the Content table, and 2.6-202309 corrected it. Payloads should always use kwarray.

Example

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

{
  "id": "req-1",
  "app": {
    "content": {
      "kwarray": [
        "cooking",
        "documentary",
        "travel"
      ]
    }
  }
}

Common mistakes

Sending kwarray alongside keywords. The validator reports the pair as mutually exclusive.
Generating the misspelled kwarry from a schema built on those snapshots. Buyers read only kwarray.
