I have a new advertiser that is launching on CJ. They are on another network (affiliate window) and run their paid media campaigns through Doubleclick. Essentially, they want to properly attribute a sale to only one source CJ, AW, or DBCK. CJ sent technical guidelines for custom parameters which would stop order duplication between CJ and AW. Is there a way to include logic so that only the pixel from the last click fires? Any help is appreciated.
