Path: user.kwarray
Object: User
Type: string array
Requirement: Optional
Added: OpenRTB 2.6-202204
Spec section: 3.2.20

Example

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

{
  "id": "req-1",
  "user": {
    "kwarray": [
      "running",
      "marathon training",
      "trail shoes"
    ]
  }
}

Common mistakes

Sending both kwarray and keywords, which the validator reports as mutually exclusive.
