SupplyChain.complete

Whether the chain reaches all the way back to the owner of the site, app, or other medium: 1 means every node is present, 0 means at least one upstream hop is missing. Required.

Field facts

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

How it is used

Set 1 only when the first node is the inventory owner's own seller account. If you received a chain marked 0, or no chain at all, the chain you forward stays incomplete after you append your node. Buyers often discount incomplete chains, and the No-Bid Reason Codes list has a value, 16, for declining a request on exactly this ground.

Allowed values

0, 1.

Example

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

{
  "id": "req-1",
  "source": {
    "schain": {
      "complete": 1
    }
  }
}

Common mistakes

Claiming 1 when an upstream partner sent no chain overstates what you know and fails buyer audits.
Omitting the field: it is required, so strict parsers reject the whole object.
Sending 0 by default on every request. The validator warns on incomplete chains because a missing hop should be rare.
