Hi, I am developing an application that uses the traffic estimation service to get some predictions for the keywords traffic for my company adds.
The issue is that for some keywords that are in one of our campaigns I get a null response from the API, also if I make multiple calls for the same keyword ate some point the response is going to be null. here is my code // Copyright 2014 Google Inc.

Can you help me with this matter?
