Hi, in the code, there is some comments like below in function uc_3dsecure_gateway().

// A little bit of a hack here. Will remove the NULL once I figure out how to pass $data around
$gateway_result = module_invoke('uc_'. $gateway_name, 'charge', $_SESSION['cart_order'], $order->order_total, NULL);

Would it be possible to know can be $data variable be passed to uc_paypal_wpp_charge($order_id, $amount, $data) now?

It seems the $data variable is very import to the success the request.

Thanks
