I'm trying to get clicks for Campaigns.
I'm developing an IOS Applications that shows campaigns, Adgroups, keywords and Ads from your adword account, The problem is that I don't know how to get the clicks and the data I put in the title of the question, In some places use in the selector of the request the name of those fields, but if I use any of the names like "Clicks", I got an error indicating that the name of the field is invalid, if someone has done it before I would like to shared with me.
I'm using the adwords api v201506.
