Creative subtypes (audio and video) value 8 means VAST 4.0 Wrapper

When to send it

Send 8 when the player follows VAST 4.0 wrappers. A 4.0 wrapper lets a buyer's ad server sit in front of the final creative and add its own tracking.

Buyers use 8 to confirm they can return a 4.0 wrapper rather than resolving the chain to an inline document themselves. It is confused with 7 and with 12 (VAST 4.1 Wrapper). Watch the numbering: 8 is followed by the two DAAST values, so the next VAST wrapper value is 12.

Example

{
  "imp": [
    {
      "audio": {
        "protocols": [
          8
        ]
      }
    }
  ]
}
