Field facts

Path: seatbid.bid.iurl
Object: Bid
Type: string
Requirement: Optional
Added: OpenRTB 2.0
Spec section: 4.2.3

Example

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

{
  "seatbid": [
    {
      "bid": [
        {
          "iurl": "https://cdn.dsp.example/preview/cr-5521.png"
        }
      ]
    }
  ]
}

Common mistakes

Adding a cache-busting parameter, which produces a new URL on every bid and defeats caching of review results.
