Question

i want to access Google analytic data and i got samples from Google data API SDK. but these coding does not working and throws exception

Execution of request failed: https://www.google.com/analytics/feeds/accounts/default

so i found the reason for this is Google updated it’s to v3.0. i searched updated coding for the C#, but i couldn’t find solution for this.

i have same problem as this, but with C#.
Exception thrown when using GData .NET Analytics API

i tried coding with doing changes as follows as it says in Google developer – https://developers.google.com/analytics/resources/articles/gdata-migration-guide#appendix_a

string userName = this.Username.Text;
string passWord = this.Password.Text;

AnalyticsService service = new AnalyticsService("AnalyticsSampleApp");
service.setUserCredentials(userName, passWord);
string googleAccountWebId = "AIXXXXXXXXXXXXXXXXXXXXXXXXXXX";
string profileFeedUrl = "https://www.googleapis.com/analytics/v2.4/data?key=" + googleAccountWebId;

DataQuery query2 = new DataQuery(profileFeedUrl);
query2.Ids = "12345678";
query2.Metrics = "ga:visits";
query2.Sort = "ga:visits";
query2.GAStartDate = DateTime.Now.AddMonths(-1).AddDays(-2).ToString("2011-08-01");
query2.GAEndDate = DateTime.Now.ToString("2013-09-01");
query2.StartIndex = 1;


DataFeed data = service.Query(query2);


foreach (DataEntry entry in data.Entries)
{
    string st=entry.Metrics[0].Value;       
}

but even i change this it throws exception in

DataFeed data = service.Query(query2);

this line. exception is as follows:

Execution of request failed: https://www.googleapis.com/analytics/v2.4/data?key=AIXXXXXXXXXXXXXXXXXXXXXX-8&start-index=1&end-date=2013-09-01&ids=12345678&metrics=ga:visits&sort=ga:visits&start-date=2011-08-01

i’m using following DLL

Google.GData.Analytics.dll
Google.GData.Client.dll
Google.GData.Extensions.dll

My Questions :

1. how can i correct this error?

2. how can i access Google analytic data? is this correct? or else what is the way to doing it??
   for a example i want to get available ProfileId and their values. (Title and Page views)

Answer 1

Analytics Account:

I am assuming you have an analytics account already if you don’t then create one, and sign up your domain here:
http://www.google.com/intl/en/analytics/

To get your API Key do this:

Follow the instructions on https://developers.google.com/analytics/resources/articles/gdata-migration-guide (Create a Project in the Google APIs Console) to generate your key Once you have it set it as part of the querystring to request to Google Analytics service, in this case:
YourAPIkEStringabcdefghijklmno

To get the profileId (Ids on the code) you should do this:

Log into your analytics account, select the desired domain on your list (blue link) click on the administrator button and on the profiles tab find the profile
configuration subtab, right there you will find the profile id in this case the eight characters long id:
12345678

Here you have some C# code to help you getting the number of visits for that Id:

public string VisitsNumber() 
    {
        string visits = string.Empty;
        string username = "[e-mail]";
        string pass = "yourpassword";
        string gkey = "?key=YourAPIkEYYourAPIkEYYourAPIkEYYourAPIkE";

    string dataFeedUrl = "https://www.google.com/analytics/feeds/data" + gkey;
    string accountFeedUrl = "https://www.googleapis.com/analytics/v2.4/management/accounts" + gkey;

    AnalyticsService service = new AnalyticsService("WebApp");
    service.setUserCredentials(username, pass);

    DataQuery query1 = new DataQuery(dataFeedUrl);

    query1.Ids = "ga:12345678";
    query1.Metrics = "ga:visits";
    query1.Sort = "ga:visits";

    //You were setting 2013-09-01 and thats an invalid date because it hasn't been reached yet, be sure you set valid dates
    //For start date is better to place an aprox date when you registered the domain on Google Analytics for example January 2nd 2012, for an end date the actual date is enough, no need to go further
    query1.GAStartDate = new DateTime(2012, 1, 2).ToString("yyyy-MM-dd"); 
    query1.GAEndDate = DateTime.Now.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;
        visits = ss;
    }

    return visits;
}

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack) 
    {
        Response.Write("Visits:" + this.VisitsNumber());
    }
}

Since the 2.4 API is not so flexible anymore, I have another post here hacking it to get the profile Id:
Getting an specific ProfileId from registered Accounts using GData .NET Analytics API 2.4 if you need to convert the code to C# you can use the Telerik converter: http://converter.telerik.com/

I think this suffice to use the 2.4 API. If you need extra help let me know.
