I have the problem with Google Adsense API. I used Services Account to authen, and this is my code:
require_once dirname(__FILE__) . '/google-api-php-client/Google_Client.php';
require_once dirname(__FILE__) . '/google-api-php-client/contrib/Google_AdSenseService.php';
require_once dirname(__FILE__) . '/google-api-php-client/contrib/Google_Oauth2Service.php';
$SERVICE_ACCOUNT_PKCS12_FILE_PATH = dirname(__FILE__) . '/keyfile.p12';
// create client object and set app name
$client = new Google_Client();
$client->setApplicationName("XXXX"); // name of your app
// set assertion credentials
$key = file_get_contents($SERVICE_ACCOUNT_PKCS12_FILE_PATH);
$auth = new Google_AssertionCredentials("YYYYYY@developer.gserviceaccount.com", // email you added to GA
array('https://www.googleapis.com/auth/adsense.readonly'), $key);
$client->setAssertionCredentials($auth);
$client->getAuth()->refreshTokenWithAssertion();
$accessToken = $client->getAccessToken();
// other settings
$client->setClientId("XYZ.apps.googleusercontent.com"); // from API console
$service = new Google_AdsenseService($client);
$optParams = array('metric' => array('earnings'), 'dimension' => 'date');
$data = $service->reports->generate('2013-01-01', '2013-03-03', $optParams);
And then I got this error messege:
Fatal error: Uncaught exception 'Google_ServiceException' with message 'Error calling GET https://www.googleapis.com/adsense/v1.3/reports?startDate=2013-01-01&endDate=2013-03-03&metric=earnings&dimension=date: (403) User does not have an AdSense account.' in /opt/lampp/htdocs/googleads/google-api-php-client/io/Google_REST.php:66 Stack trace: #0 /opt/lampp/htdocs/googleads/google-api-php-client/io/Google_REST.php(36): Google_REST::decodeHttpResponse(Object(Google_HttpRequest)) #1 /opt/lampp/htdocs/googleads/google-api-php-client/service/Google_ServiceResource.php(186): Google_REST::execute(Object(Google_HttpRequest)) #2 /opt/lampp/htdocs/googleads/google-api-php-client/contrib/Google_AdSenseService.php(849): Google_ServiceResource->__call('generate', Array) #3 /opt/lampp/htdocs/googleads/index.php(28): Google_ReportsServiceResource->generate('2013-01-01', '2013-03-03', Array) #4 {main} thrown in /opt/lampp/htdocs/googleads/google-api-php-client/io/Google_REST.php on line 66
