Field facts

Path: source.schain.ver
Object: SupplyChain
Type: string
Requirement: Required
Added: OpenRTB 2.6-202204
Spec section: 3.2.25

How it is used

IAB Tech Lab has circulated a 1.1 draft that lets nodes declare hp as 0 for systems that handle the request without being paid. Keep sending "1.0" until your partners confirm support, and make readers accept or reject other values explicitly rather than ignoring the chain.

Example

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

{
  "id": "req-1",
  "source": {
    "schain": {
      "ver": "1.0"
    }
  }
}

Common mistakes

Sending the number 1.0 instead of the string "1.0" is a type mismatch.
Copying an unrelated version, such as the OpenRTB version, into ver. The validator warns on anything other than 1.0.
