Beginning today, you no longer need to provide us with an AdWords API Application Token to access the AdWords API (v13 and v2009). This change requires no action on your part. The Application Token will simply be ignored if it continues to be included with your API requests. Note that the Developer Token is still required. We hope that this makes your life a bit easier in working with the AdWords API.
As always, we are here to answer your questions, collect feedback, and assist with migration to the v2009 API.
