[FR] It would be great to have a specific value passed as query string if payment was successful or unsuccessful

Payonline does not indicate anything on the payment status as the "Return URL". A use case would be to display a "Thank you" video if the payment seems successful (we know that it might be retracted later) and nothing otherwise. Maybe it should be a new Payonline option (successful return URL vs unsuccessful return URL).
