poddedupe 3 means Deduplicated on creative ID

The same creative, identified by Bid.crid, cannot fill two slots in one pod.

List: Pod DeduplicationValue 3

When to send it

Send 3 when the seller removes repeats of the same creative within a pod, using the creative ID in Bid.crid. Two different spots from one advertiser can still run back to back.

Bidders need stable creative IDs for this to work; an ID that changes on every bid defeats the check. It is confused with 4 (media file URL), which catches the same video under different IDs, and with 1, which is stricter.

Example

{
  "imp": [
    {
      "video": {
        "poddedupe": [
          3
        ]
      }
    }
  ]
}
