$session = new Pap_Api_Session("https://URL_to_your_Post_Affilite_Pro/server/scripts/server.php"); //set to your Post Affiliate Pro installation URL

if(!$session->login('merchant@username.com', 'password')) { //set your real merchant username/email and password
  die("Cannot login. Message: ". $session->getMessage());
}

$userID = '96beb999'; //set user ID of the affiliate for which you want to approve sale tracking code
$commissionTypeID = '649baf03'; //set ID of commission type for which is the sale tracking code defined. More info here: https://support.qualityunit.com/606422-How-to-get-commissiontypeid-for-campaign-and-commissiontype

$request = new Gpf_Rpc_GridRequest("Pap_Features_AffiliateTrackingCode_MerchantCodesGrid","getRows",$session);
$request->addFilter('comtypeId', Gpf_Data_Filter::EQUALS, $commissionTypeID); //this filter is only available since version 5.5.10.1
$request->addFilter('userid', Gpf_Data_Filter::EQUALS, $userID);

try {
  $request->sendNow();
} catch(Exception $e) {
  die("API call error: ".$e->getMessage());
}

$grid = $request->getGrid();
$recordset = $grid->getRecordset();

foreach($recordset as $rec) {
    updateStatus($rec->get('id'), $session);
    break;
}

function updateStatus($id, $session) {
    $request = new Gpf_Rpc_Request("Pap_Features_AffiliateTrackingCode_MerchantCodesForm", "saveFields", $session);

    $recordset = new Gpf_Data_RecordSet();

    $recordset->setHeader(array('id', 'name', 'value'));
    $recordset->add(array($id, 'rstatus', 'A')); //set desired status you want to set here, A=approved, P=pending, D=declined
    
    $request->addParam('fields', $recordset);

    try {
      $request->sendNow();
      //echo "tracking code approved";
    } catch(Exception $e) {
      die("API call error: ".$e->getMessage());
    }
}
