I want to check keywords for CPC. And made small script in PHP
<?php
require_once 'AuthToken.php';
$email ='[email protected]' ;
$password='password';
$client_email='[email protected]';
$userAgent='Ranks';
$developerToken='wGT6qnJwn6g';
$applicationToken='Ranks';
$authToken = new AuthToken($email, $password, 'adwords', 'PHP Code
Sample', 'GOOGLE');
$wsdl = 'https://adwords.google.com/api/adwords/v13/
TrafficEstimatorService?wsdl';
$namespace = 'https://adwords.google.com/api/adwords/v13';
$options = array(
'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
'encoding' => 'utf-8');
$headers = new SoapHeader($namespace, 'RequestHeader', array(
'authToken' => $authToken->GetAuthToken(),
'clientEmail' => $client_email,
'userAgent' => $userAgent,
'developerToken' => $developerToken,
'applicationToken' => $applicationToken));
$estimator_service= new SoapClient($wsdl, $options);
$estimator_service->__setSoapHeaders($headers);
# Create keyword structure.
$keyword =
'<keywordText>mars cruise</keywordText>' .
'<keywordType>Exact</keywordType>' .
'<language>en</language>';
# Check keyword traffic.
$request_xml =
'<checkKeywordTraffic>' .
'<requests>' . $keyword . '</requests>' .
'</checkKeywordTraffic>';
$estimates = $estimator_service->call('checkKeywordTraffic',
$request_xml);
$estimates = $estimates['checkKeywordTrafficReturn'];
?>
And have this error:
PHP Fatal error: Uncaught SoapFault exception: [Client] Function
("call") is not a valid method for this service in /var/www/test.php:36
