Google's selected buyer SDK ad contract requires this bid field, even when the general protocol marks it optional.

What it means

Google's selected buyer SDK ad contract requires this bid field, even when the general protocol marks it optional. This check applies to the selected vendor contract and integration direction.

Why it matters

The declared profile checks the published partner contract alongside canonical OpenRTB. It does not verify runtime approval or account configuration.

How to fix it

Supply the missing information through the documented field or permitted alternative for this direction.

Example that trips it

{
  "id": "req-sdk",
  "seatbid": [
    {
      "bid": [
        {
          "id": "bid",
          "impid": "1",
          "price": 1.2,
          "adomain": [
            "advertiser.example"
          ],
          "crid": "sdk-creative",
          "w": 300,
          "h": 250,
          "ext": {
            "billing_id": "123",
            "sdk_rendered_ad": {
              "id": "com.example.SDK",
              "rendering_data": "opaque"
            }
          }
        }
      ]
    }
  ]
}

Profile google-ab, OpenRTB 2.6-202606. The fixture asserts openrtb.profile.google.sdk_field_required at seatbid[0].bid[0].ext.sdk_rendered_ad.declared_ad.

Check your payload

Paste a bid request or response into the tester to see whether this code fires against it, or gate on the id in CI with the CLI: the id is stable, wording is not.
