On my site, I use Prebid and Apstag. How can I understand who won the auction? Is there a way to decrypt the CPM sent by Amazon? How to clearly understand who won Prebid / Amazon or Adx? I am trying to use this method 

        pbjs.onEvent('bidWon', function(data) {
          console.log(data.bidderCode+ ' won the ad server auction for ad unit ' +data.adUnitCode+ ' at ' +data.cpm+ ' CPM');
        });

, but if I get a won bid, Chrome extension Adwizard tells that 'Prebid Won: No'.

thank you in advance

  • Using the code mentioned in this link(http://prebid.org/dev-docs/troubleshooting-tips.html) you can get all the bids received and which all won. – Jp Mohan Jan 27 '20 at 18:32

The only way to see who won would be to check your DFP/GAM, since they are determining the final winner based on the Line Item that serves from both Prebid and Amazon UAM.

A non programmatic way to do this would be to use the Google debug tool on your page. Append your url with "&googfc" or type this in console "googletag.openConsole()". From there you'll see your ad units, you can click delivery diagnostics, and it will open a window in your DFP/GAM and you can see what Line Item won.

A programmatic way would be setup an on SlotRenderEndedEvent listener with DFP. You can then log the line item and advertiser which will give you the bid price.
