Hey,
With google adwords api, we were able to extract the google search volume for a list of keywords. We could that with TargetingIdeaService and selecting STATS instead of IDEAS in the selector as follows.
selector = {
'ideaType': 'KEYWORD',
'requestType': 'STATS'}
How can we achieve the same behavior/result (search volume for a list of any keywords) in the new ads api?
