non merchant gateway. client_id

[wCORS]

I have some confusion regarding the validate function and success. 

$client_id = (isset($get['client_id']) ? $get['client_id'] : null);

does the "$get" function return the client ID of the person making the payment?

- Problem: Assuming that Blesta require here the client ID who's making the payment, whereas, the callback doesn't return the Client ID.
