Hello,
I've been reading the AdWords API for a while and I'm still not enirely sure what service I should use in order to fetch performance data of my AdWords campaigns.
The application will work in the read-only fashion - just fetching campaign metric data.
There are two services available - "ReportDefinitionService" and "CampaignService".
I want to be able to fetch data like "Clicks", "Converted Clicks", etc. so I will need to use "Campaign Performance Report".
However, I'm not sure how I should access this report - is it through "ReportDefinitionService" or "CampaignService"?
I will be building a PHP application for this purpose using the Google API PHP client library. Do you perhaps know of a place where I could study some code samples for querying objects, and not mutating them?
Thanks!
