"KEYWORDS_PERFORMANCE_REPORT (Sep 21, 2014-Sep 27, 2014)"
If you do not want this row in your report results, include the new 
skipReportHeader HTTP header with a value of 
true.
Excluding the report summary
Similar to the header, each AdWords report for versions prior to v201409 returned a summary row with totals in its final row of output:
Total, --, --,44700
If you don't want this row in your report results, include the new 
skipReportSummary HTTP header with a value of 
true.
Note: If you do not include these headers or specify a value of 
false for both headers, your report results will include the header and summary rows, just as they did for prior versions of the AdWords API.
