Hello.
Someone deleted my previous message :-(
I tried to contact Doubleclick using this form http://support.google.com/adxbuyer/bin/request.py?&contactus=1
I want to use real time bidding so I need Ad Exchange buyer account. But www.google.com/adxbuyer logins me to Adwords account, and there is no any abilities to set up real time bidding or enable real time bidding to my campaigns, shown on this video http://goo.gl/7nTEf
On https://code.google.com/apis/console/ i've enabled API for Ad Exchange Buyer API but I have no ideas where I should provide url where google will send bid requests to. Also there is no information about account representative to get testing software (https://developers.google.com/ad-exchange/rtb/test-guide)
Please can you tell if i doing something wrong?
