Preprogrammed Report Types
The types of preprogrammed reports in the Analytics V3 Reporting API are described below. "Preprogrammed" means that the various report types each include default dimensions and metrics, without your having to specify any. You can, however, modify the preprogrammed report with whatever dimensions, metrics, or filters you want.
The report type value is specified with the report_type= query string parameter.
