Source Object

Source Object Properties
Value Type Description
fd integer

Indicates the entity responsible for the final impression sale decision, using the following values:

  • 0 = The exchange behind BidSwitch
  • 1 = An upstream source (usually header bidder)

For example a bid request containing ext.ssp='rubicon' and source.fd=0 implies that the auction is run at Rubicon SSP. If the same request has source.fd=1 then the auction is run at a header bidder upstream from Rubicon SSP.

Note: The BidSwitch platform never acts as the decision maker.
