Field facts

Path: device.dpidsha1
Object: Device
Type: string
Requirement: Optional
Added: OpenRTB 2.0
Deprecated: OpenRTB 2.6-202204
Spec section: 3.2.18

How it is used

The spec text for the 2.6-202210 through 2.6-202303 snapshots misspelled the name as dpidshal, and 2.6-202309 corrected it; payloads always used dpidsha1. The underlying platform IDs are no longer stable across apps, so the field has no good source today. Use device.ifa instead.

Example

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

{
  "id": "req-1",
  "device": {
    "dpidsha1": "0000000000000000000000000000000000000000"
  }
}

Common mistakes

Still sending it on 2.6 traffic. The validator reports it as deprecated.
