Header biding is a rather vast conception which different companies develop in their own way. Prebid.js, EBDA by Google, Amazon APS – all those are variations of header biding technology.
Headbidder.net is developed with Prebid.js but supports and has among others built-in integrations, for example, Amazon APS integration.
Headbidder.net drop-down menu synchronized with Prebid.js and contains a list of all available header bidding partners. You choose a needed partner and click ADD. Bidder will be added automatically with the needful setting made. Thus publisher does not have to download each adapter separately and manually set specific params. This job is already done.
