Google Analytics API integration with ASP.Net

// set username and password of your google analytics account account.

string userName = "";

string passWord = "";

const string dataFeedUrl = "https://www.google.com/analytics/feeds/data";

AccountQuery query = new AccountQuery();

AnalyticsService service = new AnalyticsService("AnalyticsSampleApp");

if (!string.IsNullOrEmpty(userName))

{

         service.setUserCredentials(userName, passWord);

}

string str = "";

AccountFeed accountFeed = service.Query(query);

foreach (AccountEntry entry in accountFeed.Entries)

{

     str = entry.ProfileId.Value;

}

Once you get through with GA credential process you can start doing your stuff.

The following code snippet helps you to get the total number of visits of your site; you can set the date range to retrieve the data in-between.

DataQuery query1 = new DataQuery(dataFeedUrl);

query1.Ids = str;

query1.Metrics = "ga:visits";

query1.Sort = "ga:visits";

query1.GAStartDate = DateTime.Now.AddMonths(-1).AddDays(-2).ToString("yyyy-MM-dd");

query1.GAEndDate = DateTime.Now.AddDays(-3).ToString("yyyy-MM-dd");

query1.StartIndex = 1;

DataFeed dataFeedVisits = service.Query(query1);

foreach (DataEntry entry in dataFeedVisits.Entries)

{

            string st = entry.Title.Text;

            string ss = entry.Metrics[0].Value;

            _intVisists = Int32.Parse(ss);

            Response.Write("<br/>");

            Response.Write("Total Visits : " + ss);

            Response.Write("<br/>");

}
