Field facts

Path: source.schain.nodes.sid
Object: SupplyChainNode
Type: string
Requirement: Required
Added: OpenRTB 2.6-202204
Spec section: 3.2.26

How it is used

Keep it to 64 characters or fewer. The sid in your node names the party you pay, so on a reseller hop it is the upstream partner's account with you, not your own account anywhere else.

Example

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

{
  "id": "req-1",
  "source": {
    "schain": {
      "nodes": [
        {
          "sid": "pub-4791"
        }
      ]
    }
  }
}

Common mistakes

Using an internal alias that does not appear in sellers.json makes the node unverifiable.
Sending an empty string or a number. The field is a non-empty string.
