Field facts

Path: device.sua.browsers.brand, device.sua.platform.brand
Object: BrandVersion
Type: string
Requirement: Required
Added: OpenRTB 2.6-202204
Spec section: 3.2.30

How it is used

Copy the string as the client reported it, including GREASE brands, which are intentionally odd names like "Not-A.Brand" that buyers should skip rather than reject.

Example

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

{
  "id": "req-1",
  "device": {
    "sua": {
      "browsers": {
        "brand": "Google Chrome"
      }
    }
  }
}

Common mistakes

Sending a BrandVersion with only version. The object means nothing without brand, and the validator reports the missing required field.
