title: can I use the ga:adCost and ga:hour dimensions together in google analytics?
body: <p>Considering a site with various ad campaigns...Can I get per hour details for AdWords dimensions.</p>
  
  <p>I have tried querying the Google Analytics API to fetch</p>
  
  <p>Dimensions: ga:campaign, ga:adGroup, ga:keyword, ga:date, ga:hour</p>
  
  <p>Metrics: ga:adCost</p>
  
  <p>It breaks with error message "The remote server returned an error: (400) Bad Request."</p>
  
  <p>I have tried using the API and <a href="http://ga-dev-tools.appspot.com/explorer/?csw=1" rel="nofollow">Google Analytics Query Explorer 2</a> both.</p>
  
  <p>But seems like Google Analytics don't have hour details for AdWords dimensions (e.g. ga:adCost, ga:adClicks, ga:CPC, ga:impressions)</p>
  
  <p>I could not find any documentation on the combination of dimensions I can use in a query. However I found <a href="https://developers.google.com/analytics/devguides/reporting/core/dimsmets" rel="nofollow">https://developers.google.com/analytics/devguides/reporting/core/dimsmets</a>
  But it only gives valid combinations of Dimensions and Metrics not Dimensions itself.</p>
