Answer 1

Your code is not working because Google removed all stats fields from several of its Adwords API services, including CampaignService, with the release of v201309.

To get campaign stats in v201309 or v201402, you will need to use CAMPAIGN_PERFORMANCE_REPORT instead.

Here is a PHP example of how to download a report. The example uses CRITERIA_PERFORMANCE_REPORT, whereas you are looking for CAMPAIGN_PERFORMANCE_REPORT, but code will be very similar.

You should be able to use the same selector as in your original code above.
