Программно повторить заказ битрикс D7

Скрипт js, в котором передаем id текущего заказа:

$('body').on('click', '#repeat-detail', function(e){
    $cancel = confirm("Вы уверены, что хотите повторить заказ?");
    if($cancel) {
        $id = $(this).data('order');
        var sendData = {
            id: $id
        };
        sendAjax(sendData, '/ajax/personal/personal-repeat.php', successCancelRep);
    }
});

function sendAjax(sendData, link, func) {
   $.ajax({
        url: link,
        type: 'POST',
        data: ({sendData: sendData}),
        dataType: "html",
        error: error,
        success: func
    })
}

function error(){
    alert('Ошибка при загрузке данных!');
}

function successCancelRep(result){
    window.location.reload();
}
