I am trying to create a domain shared contact in GSuite via the Contacts API in C# but unable to figure out how to POST the atom XML entry to the Feed URL as mentioned here : https://developers.google.com/admin-sdk/domain-shared-contacts/#Creating
I have tried following the older GData way mentioned here https://developers.google.com/gdata/client-cs but I get a "Execution of authentication request returned unexpected result: 404" error.
static void Main(string[] args)
{
Console.WriteLine("Hello !! ");
//Get Auth
OAuth2Parameters p = ContactsAuth();
//Create a domain shared contact
try
{
RequestSettings settings = new RequestSettings("GSuiteAdminApp", p);
ContactsRequest cr = new ContactsRequest(settings);
ContactEntry cn = new ContactEntry();
Name n = new Name();
n.GivenName = "Ice";
n.FamilyName = "Cold001";
n.FullName = "Ice Cold001";
EMail e = new EMail();
e.Rel = "http://schemas.google.com/g/2005#work";
e.Primary = true;
e.Address = "ice.cold001#xyz.com";
cn.Name = n;
cn.Emails.Add(e);
}
catch (Exception e44)
{
Console.WriteLine(e44.Message);
}
}
//Auth for Contacts API
public static OAuth2Parameters ContactsAuth()
{
string clientId = "xxxxxxxxxxxxxx.apps.googleusercontent.com";
string clientSecret = "xxxxxxxxxxxxx";
string[] scopes = new string[] { "https://www.google.com/m8/feeds/" };
try
{
UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets
{
ClientId = clientId,
ClientSecret = clientSecret
}, scopes, "super-admin#mydomain.com", CancellationToken.None, new FileDataStore("C:\\Temp\\A\\SharedContactsOauth")).Result;
// Translate the Oauth permissions to something the old client libray can read
OAuth2Parameters parameters = new OAuth2Parameters();
parameters.AccessToken = credential.Token.AccessToken;
parameters.RefreshToken = credential.Token.RefreshToken;
return parameters;
}
catch (Exception ex33)
{
Console.WriteLine(ex33.Message);
return null;
}
}
This gives a "request failed" error.
I was finally able to figure it out by stringing along code snippets from few different sources and some modifications of my own. Linda Lawton's https://www.daimto.com/google-contacts-with-c/ for the OAuth2 part using older GData API. Google's documentation on Contacts API v3.0 https://developers.google.com/contacts/v3/ for mechanics of using the .NET client library for contacts and their (bit sketchy) documentation on "domain shared contacts", especially on using the proper FeedUri and Atom entries for new contact https://developers.google.com/admin-sdk/domain-shared-contacts/#Creating.
Basically what it boils down to is this -
Use a GSuite Super Admin account to authrorize to Contacts API using OAuth2.0, then use GData Contacts .NET client library to create the new contact
by suppying your Gsuite domain in the method and you are done.
Here's the full code which I have it working for me now:
using System;
using System.Threading;
using Google.Contacts;
using Google.GData.Contacts;
using Google.GData.Client;

// Set the contact's e-mail addresses.
newEntry.Emails.Add(new EMail()
{

Rel = ContactsRelationships.IsWork,
Address = "ice.cold005#xyz.com"
});
//Insert the contact
Uri feedUri = new Uri(ContactsQuery.CreateContactsUri("test.com"));
Contact createdEntry = cr.Insert(feedUri, newEntry);
Console.WriteLine("New Contact created successfully with ContactID = " + createdEntry.Id);
return createdEntry;

My application used to work just fine, but yesterday starts to give me an error when I try to open a push notification channel via Google Drive .NET SDK, the error is:
Failed to create channel [400]
Message[Failed to create channel]
Location[ - ]
Reason[invalidArgument]
Domain[global]
You can see my code here:
public async Task<Channel> StartWebHookWatch(TokenResponse token, string userId, string channelId, string pageToken, string urlCallBack)
{
var service = GetDriveService(token);
var expireDate = DateTime.UtcNow.AddSeconds(604800); // 1 Week
var channel = new Channel()
{
Id = channelId, // Just a Guid created with "Guid.NewGuid().ToString();"
Token = userId, // Just a Id to bind the channel With My appUser
Type = "web_hook",
Address = urlCallBack, // Authorized Url
Expiration = (long)expireDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0)).TotalMilliseconds
};
return await service.Changes.Watch(channel, pageToken).ExecuteAsync();
}
private DriveService GetDriveService(TokenResponse token)
{
return new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = new UserCredential(
new GoogleAuthorizationCodeFlow(
new GoogleAuthorizationCodeFlow.Initializer() { ClientSecrets = ClientSecret }),
ClientSecret.ClientId, token),
ApplicationName = AppName
});
}
I just did a lot of tests and I don't find even a clue what is the problem...
I appreciate some help to solve this, Thank you, guys.
In Google Cloud Platform the DataProc API is enabled. I am using the same key I use to access GCS and Big query to create a new cluster per this example. I get a Request had insufficient authentication scopes error on the following line.
Operation createOperation =
service.Projects.Regions.Clusters.Create(newCluster, project, dataprocGlobalRegion).Execute();
My complete code:
public static class DataProcClient

When creating your ServiceAccountCredential, change:
new[] { StorageService.Scope.DevstorageFullControl }
to:
new[] { DataprocService.Scope.CloudPlatform }
I'm trying to retrieve data from google analytics with a local console app. Im able to extract some data without having to log in to google account and only using the API.
The problem is i'm not getting the right values and im not sure how to format the code to extract the correct values. I wan't to retrieve all visitors within a certain time frame, in this case "2012-01-01" - "2014-02-20". The real number of visitors is like 10 times larger when looking in the Google Analytics dashboard. I'm getting a number of 15000 when debugging the code. I'm displaying d.TotalResults in the console wich might be wrong, the variable "d" contains lots of different properties.
This is the code i'm running:
public static void Main(string[] args)
{
var serviceAccountEmail = "MY#developer.gserviceaccount.com";
var certificate = new X509Certificate2(#"C:\Users\User\Desktop\key.p12", "notasecret", X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { AnalyticsService.Scope.Analytics }
}.FromCertificate(certificate));
// Create the service.
//Twistandtango
var gas = new AnalyticsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "TestGoogleAnalytics",
});
var r = gas.Data.Ga.Get("ga:MYProfileID", "2012-01-01", "2014-02-20", "ga:visitors");
//Specify some addition query parameters
r.Dimensions = "ga:pagePath";
r.Sort = "-ga:visitors";
r.MaxResults = 5;
//Execute and fetch the results of our query
Google.Apis.Analytics.v3.Data.GaData d = r.Execute();
Console.WriteLine(d.TotalResults);
Console.ReadLine();
}
I'm trying to query the results I want with this tool https://ga-dev-tools.appspot.com/explorer/. When I implement this in my code it looks like this:
public static void Main(string[] args)
{
var serviceAccountEmail = "MY#developer.gserviceaccount.com";
var certificate = new X509Certificate2(#"C:\Users\User\Desktop\key.p12", "notasecret", X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { AnalyticsService.Scope.Analytics }
}.FromCertificate(certificate));
// Create the service.
//Twistandtango
var gas = new AnalyticsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "TestGoogleAnalytics",
});
var r = gas.Data.Ga.Get("ga:MYProfileID", "2012-01-01", "2014-02-20", "ga:visits");
//Specify some addition query parameters
r.Dimensions = "ga:visitCount";
r.Metrics = "ga:visits";
r.Segment = "gaid::-1";
//r.Sort = "-ga:visitors";
r.MaxResults = 10000;
//Execute and fetch the results of our query
Google.Apis.Analytics.v3.Data.GaData d = r.Execute();
Console.WriteLine(d.TotalResults);
Console.ReadLine();
}
}
However after adding the metric (r.Metrics = "ga:visits";) to the project I get this error:
Error 7 Property or indexer 'Google.Apis.Analytics.v3.DataResource.GaResource.GetRequest.Metrics' cannot be assigned to -- it is read only
Also here's a index of classes in analytics v3:
https://developers.google.com/resources/api-libraries/documentation/analytics/v3/csharp/latest/annotated.html
Does anyone have knowledge of how this works? How do i retrieve total amount of visitors from the time frame i specified??
Thx
Your problem is that you supply metrics in the data.ga.get method, you dont use r.metrics metrics add more them one separate them with a ,. In this case ga:visits is the metrics you are requesting.
var r = gas.Data.Ga.Get("ga:MYProfileID", "2012-01-01", "2014-02-20", "ga:visits");
Dimensions aren't a required filed so you could and remove r.Dimensions = "ga:visitCount"; see what that returns.
Remember that simply doing Google.Apis.Analytics.v3.Data.GaData d = r.Execute(); isn't going to return all the rows if there are more then what you have max result set to. You need to check your next link to make sure you don't have more rows.
Update in response to question below about next link.
You currently have max-results set to 10000 which is the max number of rows that can be returned in a chunk. If there are more then 10000 rows then you will get a nextlink you need to request the the next chunk of rows. TotalResult will give you the total number of rows that you should be returning. Below I keep requesting more data using .execute until there isn't anymore Next links.
List result = new List();
do {
try
{
GaData DataList = request.Execute(); // Make the request
result.AddRange(DataList.Rows); // store the Data to return later
// hack to get next link stuff
totalResults = (!DataList.TotalResults.HasValue) ? 0 : Int32.Parse(DataList.TotalResults.ToString());
rowcnt = rowcnt + DataList.Rows.Count;
NextLink = DataList.NextLink;
request.StartIndex = rowcnt + 1 ;
}
catch (Exception e)
{
Console.WriteLine("An error occurred: " + e.Message);
totalResults = 0;
}
} while (request.StartIndex <= totalResults);
I have been looking for a good solution all day, but Google evolves so fast that I can't find something working. What I want to do is that, I have a Web app that has an admin section where user need to be logged in to see the information. In this section I want to show some data from GA, like pageviews for some specific urls. Since it's not the user information that I'm showing but the google analytics'user I want to connect passing information (username/password or APIKey) but I can't find out how. All the sample I found use OAuth2 (witch, if I understand, will ask the visitor to log in using google).
What I found so far :
Google official Client Library for .Net : http://code.google.com/p/google-api-dotnet-client/, no sample for GA
official developers help : https://developers.google.com/analytics/
an other question with code on SO : Google Analytics API - Programmatically fetch page views in server side but I get a 403 when I try to authenticate
some source that access the API : http://www.reimers.dk/jacob-reimers-blog/added-google-analytics-reader-for-net downloaded the source but I can't figure out how it works
this other question on SO : Google Analytics Access with C# but it does not help
while writing this they suggest me this 09 old post Google Analytics API and .Net.
Maybe I'm just tired and that tomorrow it will be easy to find a solution but right now I need help!
Thanks
It requires a bit of setup on the google side but it's actually quite simple. I will list step by step.
First you will need to create an application in the Google cloud console and enable the Analytics API.
Go to http://code.google.com/apis/console
Select the drop down and create a project if you do not already have one
Once the project is created click on services
From here enable the Analytics API
Now that the Analytics API is enabled the next step will be to enable a service account to access your desired analytics profiles/sites. The service account will allow you to log in without having to prompt a user for credentials.
Go to http://code.google.com/apis/console and choose the project you
created from the drop down.
Next go to the "API Access" section and click the "Create another client id" button.
In the Create Client ID window choose service account and click
create client id.
Download the public key for this account if it doesn't start the
download automatically.You will need this later on when you code for
authorization.
Before exiting copy the service accounts auto generated email address as you will need this in the next step. The client email looks like #developer.gserviceaccount.com
Now that we have a service account you will need to allow this service account to access to your profiles/sites in Google Analytics.
Log into Google Analytics.
Once logged in click on the Admin button to the bottem left on the
screen.
In Admin click the account drop down and select the account/site you would like your service account to be able to access then click on "User Management" under the account section.
Enter the email address that was generated for your service account and give it read and analyze permission.
Repeat these steps for any other account/site you would like your service to have access to.
Now that the setup is done for the service account to access Google Analytics through the API we can start to code.
Get this package from NuGet:
Google.Apis.Analytics.v3 Client Library
Add these usings:
using Google.Apis.Analytics.v3;
using Google.Apis.Analytics.v3.Data;
using Google.Apis.Services;
using System.Security.Cryptography.X509Certificates;
using Google.Apis.Auth.OAuth2;
using System.Collections.Generic;
using System.Linq;
Some things to note are.
The keyPath is the path to the key file you downloaded with a .p12 file extention.
The accountEmailAddress is the api email we got earlier.
Scope is an Enum in the Google.Apis.Analytics.v3.AnalyticService class that dictates the url to use in order to authorize (ex: AnalyticsService.Scope.AnalyticsReadonly ).
Application name is a name of your choosing that tells the google api what is accessing it (aka: it can be what ever you choose).
Then the code to do some basic calls is as follows.
public class GoogleAnalyticsAPI
{
public AnalyticsService Service { get; set; }
public GoogleAnalyticsAPI(string keyPath, string accountEmailAddress)
{
var certificate = new X509Certificate2(keyPath, "notasecret", X509KeyStorageFlags.Exportable);
var credentials = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(accountEmailAddress)
{
Scopes = new[] { AnalyticsService.Scope.AnalyticsReadonly }
}.FromCertificate(certificate));
Service = new AnalyticsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credentials,
ApplicationName = "WorthlessVariable"
});
}
public AnalyticDataPoint GetAnalyticsData(string profileId, string[] dimensions, string[] metrics, DateTime startDate, DateTime endDate)
{
AnalyticDataPoint data = new AnalyticDataPoint();
if (!profileId.Contains("ga:"))
profileId = string.Format("ga:{0}", profileId);
//Make initial call to service.
//Then check if a next link exists in the response,
//if so parse and call again using start index param.
GaData response = null;
do
{
int startIndex = 1;
if (response != null && !string.IsNullOrEmpty(response.NextLink))
{
Uri uri = new Uri(response.NextLink);
var paramerters = uri.Query.Split('&');
string s = paramerters.First(i => i.Contains("start-index")).Split('=')[1];
startIndex = int.Parse(s);
}
var request = BuildAnalyticRequest(profileId, dimensions, metrics, startDate, endDate, startIndex);
response = request.Execute();
data.ColumnHeaders = response.ColumnHeaders;
data.Rows.AddRange(response.Rows);
} while (!string.IsNullOrEmpty(response.NextLink));
return data;
}
private DataResource.GaResource.GetRequest BuildAnalyticRequest(string profileId, string[] dimensions, string[] metrics,
DateTime startDate, DateTime endDate, int startIndex)
{
DataResource.GaResource.GetRequest request = Service.Data.Ga.Get(profileId, startDate.ToString("yyyy-MM-dd"),
endDate.ToString("yyyy-MM-dd"), string.Join(",", metrics));
request.Dimensions = string.Join(",", dimensions);
request.StartIndex = startIndex;
return request;
}
public IList<Profile> GetAvailableProfiles()
{
var response = Service.Management.Profiles.List("~all", "~all").Execute();
return response.Items;
}
public class AnalyticDataPoint
{
public AnalyticDataPoint()
{
Rows = new List<IList<string>>();
}
public IList<GaData.ColumnHeadersData> ColumnHeaders { get; set; }
public List<IList<string>> Rows { get; set; }
}
}

Hopefully this helps someone trying to do this in the future.
I did a lot of search and finally either looking up code from multiple places and then wrapping my own interface around it i came up with the following solution. Not sure if people paste their whole code here, but i guess why not save everyone else time :)
Pre-requisites, you will need to install Google.GData.Client and google.gdata.analytics package/dll.
This is the main class that does the work.
namespace Utilities.Google
{
public class Analytics
{
private readonly String ClientUserName;
private readonly String ClientPassword;
private readonly String TableID;
private AnalyticsService analyticsService;
public Analytics(string user, string password, string table)
{
this.ClientUserName = user;
this.ClientPassword = password;
this.TableID = table;
// Configure GA API.
analyticsService = new AnalyticsService("gaExportAPI_acctSample_v2.0");
// Client Login Authorization.
analyticsService.setUserCredentials(ClientUserName, ClientPassword);
}
/// <summary>
/// Get the page views for a particular page path
/// </summary>
/// <param name="pagePath"></param>
/// <param name="startDate"></param>
/// <param name="endDate"></param>
/// <param name="isPathAbsolute">make this false if the pagePath is a regular expression</param>
/// <returns></returns>
public int GetPageViewsForPagePath(string pagePath, DateTime startDate, DateTime endDate, bool isPathAbsolute = true)
{
int output = 0;
// GA Data Feed query uri.
String baseUrl = "https://www.google.com/analytics/feeds/data";
DataQuery query = new DataQuery(baseUrl);
query.Ids = TableID;
//query.Dimensions = "ga:source,ga:medium";
query.Metrics = "ga:pageviews";
//query.Segment = "gaid::-11";
var filterPrefix = isPathAbsolute ? "ga:pagepath==" : "ga:pagepath=~";
query.Filters = filterPrefix + pagePath;
//query.Sort = "-ga:visits";
//query.NumberToRetrieve = 5;
query.GAStartDate = startDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
query.GAEndDate = endDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
Uri url = query.Uri;
DataFeed feed = analyticsService.Query(query);
output = Int32.Parse(feed.Aggregates.Metrics[0].Value);
return output;
}
public Dictionary<string, int> PageViewCounts(string pagePathRegEx, DateTime startDate, DateTime endDate)
{
// GA Data Feed query uri.
String baseUrl = "https://www.google.com/analytics/feeds/data";
DataQuery query = new DataQuery(baseUrl);
query.Ids = TableID;
query.Dimensions = "ga:pagePath";
query.Metrics = "ga:pageviews";
//query.Segment = "gaid::-11";
var filterPrefix = "ga:pagepath=~";
query.Filters = filterPrefix + pagePathRegEx;
//query.Sort = "-ga:visits";
//query.NumberToRetrieve = 5;
query.GAStartDate = startDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
query.GAEndDate = endDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
Uri url = query.Uri;
DataFeed feed = analyticsService.Query(query);
var returnDictionary = new Dictionary<string, int>();
foreach (var entry in feed.Entries)
returnDictionary.Add(((DataEntry)entry).Dimensions[0].Value, Int32.Parse(((DataEntry)entry).Metrics[0].Value));
return returnDictionary;
}
}
}
And this is the interface and implementation that i use to wrap it up with.
namespace Utilities
{
public interface IPageViewCounter
{
int GetPageViewCount(string relativeUrl, DateTime startDate, DateTime endDate, bool isPathAbsolute = true);
Dictionary<string, int> PageViewCounts(string pagePathRegEx, DateTime startDate, DateTime endDate);
}
public class GooglePageViewCounter : IPageViewCounter
{
private string GoogleUserName
{
get
{
return ConfigurationManager.AppSettings["googleUserName"];
}
}
private string GooglePassword
{
get
{
return ConfigurationManager.AppSettings["googlePassword"];
}
}
private string GoogleAnalyticsTableName
{
get
{
return ConfigurationManager.AppSettings["googleAnalyticsTableName"];
}
}
private Analytics analytics;
public GooglePageViewCounter()
{
analytics = new Analytics(GoogleUserName, GooglePassword, GoogleAnalyticsTableName);
}
#region IPageViewCounter Members
public int GetPageViewCount(string relativeUrl, DateTime startDate, DateTime endDate, bool isPathAbsolute = true)
{
int output = 0;
try
{
output = analytics.GetPageViewsForPagePath(relativeUrl, startDate, endDate, isPathAbsolute);
}
catch (Exception ex)
{
Logger.Error(ex);
}
return output;
}
public Dictionary<string, int> PageViewCounts(string pagePathRegEx, DateTime startDate, DateTime endDate)
{
var input = analytics.PageViewCounts(pagePathRegEx, startDate, endDate);
var output = new Dictionary<string, int>();
foreach (var item in input)
{
if (item.Key.Contains('&'))
{
string[] key = item.Key.Split(new char[] { '?', '&' });
string newKey = key[0] + "?" + key.FirstOrDefault(k => k.StartsWith("p="));
if (output.ContainsKey(newKey))
output[newKey] += item.Value;
else
output[newKey] = item.Value;
}
else
output.Add(item.Key, item.Value);
}
return output;
}
#endregion
}
}
And now the rest is the obvious stuff - you will have to add the web.config values to your application config or webconfig and call IPageViewCounter.GetPageViewCount
This answer is for those of you who want access to your own Analytics account and want to use the new Analytics Reporting API v4.
I recently wrote a blog post about how to get Google Analytics data using C#. Read there for all the details.
You first need to choose between connecting with OAuth2 or a Service Account. I'll assume you own the Analytics account, so you need to create a "Service account key" from the Google APIs Credentials page.
Once you create that, download the JSON file and put it in your project (I put mine in my App_Data folder).
Next, install the Google.Apis.AnalyticsReporting.v4 Nuget package. Also install Newtonsoft's Json.NET.
Include this class somewhere in your project:
public class PersonalServiceAccountCred
{
public string type { get; set; }
public string project_id { get; set; }
public string private_key_id { get; set; }
public string private_key { get; set; }
public string client_email { get; set; }
public string client_id { get; set; }
public string auth_uri { get; set; }
public string token_uri { get; set; }
public string auth_provider_x509_cert_url { get; set; }
public string client_x509_cert_url { get; set; }
}
And here's what you've been waiting for: a full example!
string keyFilePath = Server.MapPath("~/App_Data/Your-API-Key-Filename.json");
string json = System.IO.File.ReadAllText(keyFilePath);
var cr = JsonConvert.DeserializeObject(json);
var xCred = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(cr.client_email)
{
Scopes = new[] {
AnalyticsReportingService.Scope.Analytics
}
}.FromPrivateKey(cr.private_key));
using (var svc = new AnalyticsReportingService(
new BaseClientService.Initializer
{
HttpClientInitializer = xCred,
ApplicationName = "[Your Application Name]"
})
)
{
// Create the DateRange object.
DateRange dateRange = new DateRange() { StartDate = "2017-05-01", EndDate = "2017-05-31" };
// Create the Metrics object.
Metric sessions = new Metric { Expression = "ga:sessions", Alias = "Sessions" };
//Create the Dimensions object.
Dimension browser = new Dimension { Name = "ga:browser" };
// Create the ReportRequest object.
ReportRequest reportRequest = new ReportRequest
{
ViewId = "[A ViewId in your account]",
DateRanges = new List() { dateRange },
Dimensions = new List() { browser },
Metrics = new List() { sessions }
};
List requests = new List();
requests.Add(reportRequest);
// Create the GetReportsRequest object.
GetReportsRequest getReport = new GetReportsRequest() { ReportRequests = requests };
// Call the batchGet method.
GetReportsResponse response = svc.Reports.BatchGet(getReport).Execute();
}
We start by deserializing the service account key information from the JSON file and convert it to a PersonalServiceAccountCred object. Then, we create the ServiceAccountCredential and connect to Google via the AnalyticsReportingService. Using that service, we then prepare some basic filters to pass to the API and send off the request.
It's probably best to set a breakpoint on the line where the response variable is declared, press F10 once, then hover over the variable, so you can see what data is available for you to use in the response.
I was hoping just to add a comment to the answer for v3 Beta, but rep points prevent that. However, I thought it would be nice for others to have this information so here it is:
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using System.Security.Cryptography.X509Certificates;
using Google.Apis.Services;
These name spaces are used throughout the code in that post. I always wish people would post name spaces more often, I seem to spend a good bit of time looking for them. I hope this saves some people a few minutes of work.
I've setup something pretty similar to the above answer in a nuGet package. It does the following:
- connects to a "Service Account" you set up in the API Console
- Pulls any Google Analytics data you would like
- Displays that data using Google's Charts API
and it does all of this in a very easy to modify way. You can see more here: https://www.nuget.org/packages/GoogleAnalytics.GoogleCharts.NET/.
Hope google will provide proper documentation someday. Here I am listing all the steps to integrate google analytics server side authentication in ASP.NET C#.
Step 1: Create a project in google console
Goto the link https://console.developers.google.com/iam-admin/projects and create a project by clicking on "Create Project" button and provide project name in the pop up window and submit it.
Step 2: Create credentials and service account
After creation of the project, you will be redirected to "API Manager" page.
Click on credentials and press "Create Credentials" button. select "service account key" from dropdown you will be redirected to next page.
In the service account drop down, select "New service account". Fill in the service account name and download the p12 key. It will have p12 extension. you will get a popup having a password "notasecret" which is default and your private key will be downloaded.
Step 3: Create 0auth client ID
click on the "create credentials" dropdown and select "0auth client ID" you will be redirected to "0auth consent screen" tab. provide a random name in the project name textbox. select application type as "Web application" and click create button. Copy the generated client ID in a notepad.
Step 4: Enable the APIs
On the left side click on the "Overview" tab and select "Enabled APIs" from the horizontal tab. In the search bar search for "Analytics API" click on the dropdown and press "Enable" button. Now again search for "Analytics Reporting V4" and enable it.
Step 5: Install nuget packages
In visual studio, Go to Tools > Nuget Package Manager > Package Manager Console.
Copy paste the below code in the console to install the nuget packages.
Install-Package Google.Apis.Analytics.v3
Install-Package DotNetOpenAuth.Core -Version 4.3.4.13329
The above two packages are Google analytics and DotNetOpenAuth nuget packages.
Step 6: Provide 'View and Analyze' permission to service account
Go to google analytics account and click on "Admin" tab and select "User Management" from left menus,select a domain of which you want to access analytics data and insert the service account email id under it and select "Read and Analyze" permission from the dropdown. Service account email id looks like ex: googleanalytics#googleanalytics.iam.gserviceaccount.com.
Working Code
FRONT END CODE:
Copy and paste the below analytics embed script in your front end or else you can get this code from google analytics documentation page also.
<script>
(function (w, d, s, g, js, fs) {
g = w.gapi || (w.gapi = {}); g.analytics = { q: [], ready: function (f) { this.q.push(f); } };
js = d.createElement(s); fs = d.getElementsByTagName(s)[0];
js.src = 'https://apis.google.com/js/platform.js';
fs.parentNode.insertBefore(js, fs); js.onload = function () { g.load('analytics'); };
}(window, document, 'script'));</script>
Paste the below code in the body tag of your front end page.
<asp:HiddenField ID="accessToken" runat="server" />
<div id="chart-1-container" style="width:600px;border:1px solid #ccc;"></div>
<script>
var access_token = document.getElementById('<%= accessToken.ClientID%>').value;
gapi.analytics.ready(function () {
/**
* Authorize the user with an access token obtained server side.
*/
gapi.analytics.auth.authorize({
'serverAuth': {
'access_token': access_token
}
});
/**
* Creates a new DataChart instance showing sessions.
* It will be rendered inside an element with the id "chart-1-container".
*/
var dataChart1 = new gapi.analytics.googleCharts.DataChart({
query: {
'ids': 'ga:53861036', // VIEW ID <-- Goto your google analytics account and select the domain whose analytics data you want to display on your webpage. From the URL ex: a507598w53044903p53861036. Copy the digits after "p". It is your view ID
'start-date': '2016-04-01',
'end-date': '2016-04-30',
'metrics': 'ga:sessions',
'dimensions': 'ga:date'
},
chart: {
'container': 'chart-1-container',
'type': 'LINE',
'options': {
'width': '100%'
}
}
});
dataChart1.execute();
/**
* Creates a new DataChart instance showing top 5 most popular demos/tools
* amongst returning users only.
* It will be rendered inside an element with the id "chart-3-container".
*/
});
</script>
You can also get your View ID from https://ga-dev-tools.appspot.com/account-explorer/

Another Working Approach
Add below code in the ConfigAuth
var googleApiOptions = new GoogleOAuth2AuthenticationOptions()
{
AccessType = "offline", // can use only if require
ClientId = ClientId,
ClientSecret = ClientSecret,
Provider = new GoogleOAuth2AuthenticationProvider()
{
OnAuthenticated = context =>
{
context.Identity.AddClaim(new Claim("Google_AccessToken", context.AccessToken));
if (context.RefreshToken != null)
{
context.Identity.AddClaim(new Claim("GoogleRefreshToken", context.RefreshToken));
}
context.Identity.AddClaim(new Claim("GoogleUserId", context.Id));
context.Identity.AddClaim(new Claim("GoogleTokenIssuedAt", DateTime.Now.ToBinary().ToString()));
var expiresInSec = 10000;
context.Identity.AddClaim(new Claim("GoogleTokenExpiresIn", expiresInSec.ToString()));
return Task.FromResult(0);
}
},
SignInAsAuthenticationType = DefaultAuthenticationTypes.ApplicationCookie
};
googleApiOptions.Scope.Add("openid"); // Need to add for google+
googleApiOptions.Scope.Add("profile");// Need to add for google+
googleApiOptions.Scope.Add("email");// Need to add for google+
googleApiOptions.Scope.Add("https://www.googleapis.com/auth/analytics.readonly");
app.UseGoogleAuthentication(googleApiOptions);
Add below code, name spaces and relative references
using Google.Apis.Analytics.v3;
using Google.Apis.Analytics.v3.Data;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Auth.OAuth2.Flows;
using Google.Apis.Auth.OAuth2.Responses;

public class HomeController : Controller

}
public async Task<ActionResult> AccountList()
{

{

ApplicationName = "Analytics API sample",
});
//Account List
ManagementResource.AccountsResource.ListRequest AccountListRequest = service.Management.Accounts.List();
//service.QuotaUser = "MyApplicationProductKey";
Accounts AccountList = AccountListRequest.Execute();
return View();
}
private async Task<UserCredential> GetCredentialForApiAsync()
{
var initializer = new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = ClientId,
ClientSecret = ClientSecret,
},
Scopes = new[] { "https://www.googleapis.com/auth/analytics.readonly" }
};
var flow = new GoogleAuthorizationCodeFlow(initializer);
var identity = await AuthenticationManager.GetExternalIdentityAsync(DefaultAuthenticationTypes.ApplicationCookie);
if (identity == null)
{
Redirect("/Account/Login");
}
var userId = identity.FindFirstValue("GoogleUserId");
var token = new TokenResponse()
{
AccessToken = identity.FindFirstValue("Google_AccessToken"),
RefreshToken = identity.FindFirstValue("GoogleRefreshToken"),
Issued = DateTime.FromBinary(long.Parse(identity.FindFirstValue("GoogleTokenIssuedAt"))),
ExpiresInSeconds = long.Parse(identity.FindFirstValue("GoogleTokenExpiresIn")),
};
return new UserCredential(flow, userId, token);
}
}
Add this in the Application_Start() in Global.asax
AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;
