Display Google Analytics data on my web site?
In case some one else is having the same problem here's what I did and it pretty much answers the question.
1.
Here is the basic code for a API client that access data from Google Analytics via your Google Service Account. https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth#service_account
In order to make this application work you need to have several things ready before you start coding.
*Google Analytics Account - once registered a "tracker" code is generated for you to put on each webpage you want to track. You may not see any statistics right away and it can take up to 24h before any statistics are shown in the Google Analytics Dashboard.
An OAuth Authorisation (API-Key) with CLIENT_ID, CLIENT SECRET and EMAIL ADRESS (This is not your normal email but a service account email that is created for you when you make an OAuth Authorisation). console.developers.google.com/
A serverkey, can also be created here: console.developers.google.com/. You can also create a browser key, haven't bothered with that though and don't know what it does.
Finally you need a certificate key. Your application will only be able to access your Google Analytics account by using the key and credentials. The key is an encrypted p.12 file. You can find the key in https://code.google.com/apis/console/.
Here is a guide for the key: http://www.pimcore.org/wiki/display/PIMCORE/Setup+Google+Analytics+Reporting+with+OAuth2+Service+Accounts+(since+1.4.6)

Now that you have all keys and credentials you need it is time to start looking at the code I linked in "1". Here is the basic for it again: https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth#service_account
Create a console application and implement the code above.
Note: your not making a "Google Plus service" so you have to change those parts for "AnalyticsService". Go to manage nuget and install packages:
- Google Apis Core Library
- Google Apis Client Library
- Google Apis Auth Client Library
- Google Apis Analytics.v3 Library
- Google GData Client (This provides properties used to query data, metrics, demensions etc)
- Google GData Extensions Library
- Analytics
Might forgot something but here are the namespaces I use:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Security.Cryptography.X509Certificates;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Analytics.v3;

Finally, here's is some of my code. Note I'm creating a new Analytics as supposed to "new ServiceAccountCredentials" as in the code from Google. That's the main difference: Retrieve data from Google Analytics API with .NET, multiple metrics?
With this I'm able to access and query data from Google Analytics account. The best part is that you don't have to log in to Google for this as the key and credentials gives you access to the account data directly.
I will migrate this code to MVC now I might make an update later on for how to implement this Analytics client in Mvc.
I'd recommend to use the new Google APIs Client Library for .NET (currently in beta). Information about the Analytics API can be found here. Note that the Client Library for .NET (google-api-dotnet-client) supersedes the .NET library for the Google Data API (google-gdata).
Unfortunately, there is no sample code available yet from Google (see this issue) but this question on SO should help.
If you don't want to login every time you access Analytics data, you can use OAuth 2.0 authorization with offline access. You have to grant initial access to your web application, though. This requires you to login once but you can use a refresh token later on.
This document explains how to get Google Access tokens and use them to get Google Analytics data to be displayed in our websites.
Example: A live example is available in
https://newtonjoshua.com
Note: Use the same Gmail account for all the below steps.
STEP 1: Set Up Google Analytics
Follow the below steps to set up Google Analytics on your website
- Sign in to your Analytics account.
- Select the Admin tab.
- Select an account from the drop-down menu in the ACCOUNT column.
- Select a property from the drop-down menu in the PROPERTY column.
- Under PROPERTY, click Tracking Info -> Tracking Code.
- To collect data, you must copy and paste the Analytics tracking code into the source code on every web page you wish to track.
- Once you have the JavaScript tracking code snippet for your property, copy the snippet exactly without editing it.
- Paste your tracking code snippet (unaltered, in its entirety) before the closing </head> tag on every web page on your site you wish to track.
- Once you have successfully installed Analytics tracking, it may take up to 24 hours for data such as traffic referral information, user characteristics, and browsing information to appear in your reports

STEP 2: Get Tokens
Google Project:
To create a Google Cloud Platform project, open the Google Developers Console (https://console.developers.google.com) and click Create Project.
Enable OAuth 2.0 API access:
Your application will need to access user data and contact other Google services on your behalf. Use OAuth 2.0 to grant your app API access.
To enable that, you need a client ID:
- Open the Google API Console Credentials page (https://console.developers.google.com/apis/credentials).
- From the project, drop-down and select your project.
- Select Create credentials and choose OAuth client ID.
- Under Application type, select Web application, enter a Name and
set the Restrictions by entering JavaScript origins, Redirect URIs to point the website where you are planning to display the data, and then click Create.
Make note of the OAuth 2.0 client_id and client_secret. You will need them to configure the UI.
Get Authorization code:
Enter in browser:
https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/analytics.readonly&response_type=code&client_id={{ client_id}}&redirect_uri={{redirect_uri }} &approval_prompt=force&access_type=offline
You will get redirected to
{{redirect_uri }}?code=={{authorization_code}}#
Get Refresh Token:
Send a POST request, possibly via a REST console to
https://www.googleapis.com/oauth2/v3/token?code={{authorization_code}} &client_id={{client_id}}&client_secret={{client_secret}} &redirect_uri={{redirect_uri }}&grant_type=authorization_code
You will get a JSON response with
{"refresh_token": refresh_token}
You can use the refresh token to get access token to access to Google APIs.
Get the Access Token:
Send a POST request to,
https://www.googleapis.com/oauth2/v3/token?client_id={{client_id}} &client_secret={{client_id}} &grant_type=refresh_token&refresh_token={{refresh_token}}
You will get a JSON with access_token in the response.
{access_token: {{access_token}}}
Example:
var access_token = '';
function getAccessToken(){
$.post('https://www.googleapis.com/oauth2/v3/token', {
client_id: {{client_id}},
client_secret: {{client_secret}},
grant_type: 'refresh_token',
refresh_token: {{refresh_token}}
}, function (data, status) {
if (status === 'success') {
access_token = data.access_token;
// Do something eith the access_token
}
else {
console.error(status);
}
});
}
Check Token validity:
Send a POST request to,
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={{access_token}}
Example:
function checkValidity() {
$.post('https://www.googleapis.com/oauth2/v1/tokeninfo', {
access_token:{{access_token}}
}).done(function (data, status) {
if (status === 'success') {
console.debug(data.expires_in);
var check = false;
check = data.hasOwnProperty('expires_in');
if (check) {
// Token is valid
}
if (!check) {
getAccessToken();
}
}
else {
console.debug(status);
}
})
.fail(function (data) {
console.error(data);
getAccessToken();
});
}
Step 3: Fetch Data
Embed API:
The GA Embed API is a JavaScript library that allows you to easily create and embed your GA dashboard on your website in a matter of minutes.
Refer to https://developers.google.com/analytics/devguides/reporting/embed/v1/getting-started.
Query Explorer:
Visit Embed API Query Explorer and authorize
https://ga-dev-tools.appspot.com/query-explorer/
Select the view for which you want to fetch the data.
Select the required metrics and dimensions.
Example:
Get Country Data (I want to know the number of users accessing my website from each country).
To get that data, select the metrics as 'users' and the dimensions as 'country'.
Click on Run Query.
You will find the analytics data for the query displayed in a table.
Copy the API Query URI. And add access_token={{access_token}} to the URI.
Example:
https://www.googleapis.com/analytics/v3/data/ga?ids={{ids}}&start-date=2015-07-01&end-date=today&metrics=ga%3Ausers&dimensions=ga%3Acountry&access_token={{access_token}}
Send POST request to the URIs to get the data in your browser.
Example:
function gaGetCountry() {
$.get('https://www.googleapis.com/analytics/v3/data/ga?' +
'ids={{ids}}' +
'start-date=2015-07-01&' +
'end-date=today&' +
'metrics=ga%3Ausers&' +
'dimensions=ga%3Acountry&' +
'sort=ga%3Ausers&' +
'filters=ga%3Ausers%3E10&' +
'max-results=50' +
'&access_token=' + {{access_token}},
function (data, status) {
if (status === 'success') {
// Display the Data
drawRegionsMap(data.rows);
} else {
console.debug(status);
}
});
}
Step 4: Display Data
Now we have gathered the data. Finally we have to display them on our website.
"Display live data on your site" is the title of Google Charts. And that is what we are going to do.
Refer to https://developers.google.com/chart/.
The following example will draw a GeoChart in the div with id='countryChart'.
// Draw country chart
function drawRegionsMap(data) {
var head = data[0];
head[0] = 'Country';
head[1] = 'Users';
for (var i = 1; i < data.length; i++) {
var d = data[i];
d[1] = Number(d[1]);
}
var chartData = google.visualization.arrayToDataTable(data);
var options = {
title: 'My Website is viewed from,',
domain: '{{Country Code eg: IN for India}}',
tooltip: {
textStyle: {
color: 'navy'
},
showColorCode: true
},
legend: {
textStyle: {
color: 'navy',
fontSize: 12
}
},
colorAxis: {
colors: ['#00FFFF', '#0000FF']
}
};
var chart = new google.visualization.GeoChart(document.getElementById('countryChart'));
chart.draw(chartData, options);
}
