are you still gonna use after Nov 1? They start to charge, and from my experience - adding an aads group with keywords costs 10c -15c... sucks!
Can't live without the API when you're managing 20M+ keywords and $250M+ in spend. With the 'no-impression' feature the fees shouldn't be too bad. -Shorebreak
Whenever it is necessary for us to use the google adwards API, we should use them though it is payable.
