PHP Google Analytics API - Simple example

Question

I am trying to set some basic example of using Google Analytics with this library: https://github.com/google/google-api-php-client

For starter I have:

<?php

require_once 'Google/Client.php';
require_once 'Google/Service/Analytics.php';
$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");
$client->setDeveloperKey("MY_SECRET_API"); //security measures
$service = new Google_Service_Analytics($client);

$results = $service->data_ga;

echo '<pre>';
print_r($results);
echo '</pre>';

Q: How to get data from Google Analytics from this query ?

/*
  https://www.googleapis.com/analytics/v3/data/
  ga?ids=ga%123456
  &dimensions=ga%3Acampaign
  &metrics=ga%3Atransactions
  &start-date=2013-12-25
  &end-date=2014-01-08
  &max-results=50
 */

Answer 1

$client->setDeveloperKey("MY_SECRET_API");

First of all, for as far as I experienced this won't work for authentication, you'll need to use a OAuth2 authentication. There are two options to do this, using client ID for web application or using a service account. Authorization api

After you have this, you can make a call like this. (I use a service account here)

First authenticate:

$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
    $service_account_name,
    array('https://www.googleapis.com/auth/analytics.readonly'),
    $key
);
$client->setAssertionCredentials($cred);

Make a call:

$ids = 'ga:123456'; //your id
$startDate = '2013-12-25';
$endDate = '2014-01-08';
$metrics = 'ga:transactions';

$optParams = array(
    'dimensions' => 'ga:campaign',
    'max-results' => '50'
);

$results = $service->data_ga->get($ids, $startDate, $endDate, $metrics, $optParams);

//Dump results
echo "<h3>Results Of Call:</h3>";

echo "dump of results";
var_dump($results);

echo "results['totalsForAllResults']";
var_dump($results['totalsForAllResults']);

echo "results['rows']";
foreach ($results['rows'] as $item) {
    var_dump($item);
}

You will need to do a http get to get the information from the url.

Remember you will still need to add the Oauth2 auth code to the string before you can send that request. This link might help if you dont have auth code already. https://developers.google.com/analytics/solutions/articles/hello-analytics-api#authorize_access

Answer 3

what you could do is create a new function...

function ga_campaign_transactions($gaEmail, $gaPass, $gProfile, $limit)
{
    require_once('classes/google-analytics/gapi.class.php');

    $gDimensions = array('campaign');
    $gMetrics = array('transactions');
    $gSortMetric = NULL;
    $gFilter = '';
    $gSegment = '';
    $gStartDate = '2013-12-25';
    $gEndDate = '2014-01-08';
    $gStartIndex = 1;
    $gMaxResults = $limit;

    $ga = new gapi($gaEmail, $gaPass);
    $ga->requestReportData($gProfile, $gDimensions, $gMetrics, $gSortMetric, $gFilter, $gSegment, $gStartDate, $gEndDate, $gStartIndex, $gMaxResults);

    $gAnalytics_results = $ga->getResults();

    //RETURN RESULTS
    return $gAnalytics_results;

}


$gProfile = '123456';              // The Profile ID for the account, NOT GA:
$gaEmail = 'YOUR GOOGLE EMAIL';    // Google Email address.
$gaPass  = 'YOUR GOOGLE PASSWORD'; // Google Password.
// NOTE: if 2 step login is turned on, create an application password.

$limit   = 50;
$ga_campaign_transactions = ga_campaign_transactions($gaEmail, $gaPass, $gProfile, $limit)

//OUTPUT
if(!empty($ga_campaign_transactions))
{
    $counter=0;
    $gaCampResults= array(); // CREATE ARRAY TO STORE ALL RESULTS
    foreach($ga_campaign_transactions as $row)
    {

        $dim_list = $row->getDimesions();
        $met_list = $row->getMetrics();

        $gaCampResults[$counter]['campaign'] = $dim_list['campaign'];
        $gaCampResults[$counter]['transactions'] = $met_list['transactions'];
    $counter++;
    }
 }


 if(!empty($gaCampResults))
 {
     $totalCampTransactions = count($gaCampResults);
     ?>
     <h2>We Found ( <?php echo number_format($totalCampTransactions,0);?> ) Results</h2>
     <ul>
     <?php
     foreach($gaCampResults as $gaRow){
       echo "<li>Campaign:".$gaRow['campaign']." | Transactions: ".$gaRow['transactions']."</li>";
     }
     ?>
     </ul>
     <?php
 }

find Analytics Profile ID

Create Google Application password

Hopefully that puts you on the right track :) untested this, but similar to what I've been using...
