why "Keywords Performance Report" are different than result from MCC ?

[Minius]

Hi,

I try to get keywords performance report by using HTTP REQUEST 
(https://developers.google.com/adwords/api/docs/guides/reporting?hl=lt#adhoc).

Everything works fine, no error appears. But line of "Total" are different 
comparing data with from MCC. Currently "total cost" and click count are 
different. "Avg. CPC" is ok.

Whats wrong? I try to get report for LAST_MONTH.

Each time, when i try to get report data, "total" are less than from MCC.

Maybe someone have suggestions?

My script is:


    $username = "xxx";
    $password = "xxx";
    $customerId = "26161561651561561"; 
    $devToken = "dasfws46aer546r5g1er6a51";
     
    $url = "https://www.google.com/accounts/ClientLogin";;
    $params = array(
        "accountType" => "GOOGLE",
        "Email" => $username,
        "Passwd" => $password,
        "service" => "adwords",
        "source" => "test"
    );
     
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
    //curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $curlData = curl_exec($curl);
    curl_close($curl);
     
    $curlData = explode("\n", $curlData);
    $return = array();
    foreach ($curlData as $value) {
        $value = explode("=", $value, 2);
        if (count($value) > 1) {
            $return[$value[0]] = $value[1];
        }
    }

    $authToken = $return["Auth"];
    
    #
    $httpHeaders = array(
        "Authorization: GoogleLogin auth=$authToken",
        "clientCustomerId: $customerId",
        "developerToken: $devToken"
    );
    
    #
    $reportDefinition = "<reportDefinition>"; 
    $reportDefinition .= "<selector>";

    $reportDefinition .= "<downloadFormat>CSV</downloadFormat>";
    $reportDefinition .= 
"<includeZeroImpressions>true</includeZeroImpressions>";
    $reportDefinition .= "</reportDefinition>";
     
    $params = array("__rdxml" => $reportDefinition);
    
    
    #
    $url = "https://adwords.google.com/api/adwords/reportdownload/v201109";;
 
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $params);

    //curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $reportData = curl_exec($curl);
    curl_close($curl);
     
    print "$reportData\n";
