Native.ver

Version of the Native Ads specification that Native.request follows, such as 1.2. Recommended, because parsers read 1.0, 1.1, and 1.2 requests differently.

Field facts

Path: imp.native.ver
Object: Native
Type: string
Requirement: Recommended
Added: OpenRTB 2.3
Spec section: 3.2.9

How it is used

Send the same version here and in the ver field inside the decoded request, so a buyer can choose its parser before decoding.

Example

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

{
  "id": "req-1",
  "imp": [
    {
      "native": {
        "ver": "1.2"
      }
    }
  ]
}

Common mistakes

Declaring 1.2 here while the request still uses the 1.0 wrapper or fields that Native 1.1 replaced, such as layout.
