Hello Jonathan,

Currently using IC 5.4 and Authorizenet.

I noticed the following line (from AuthorizeNet.pm):
    x_Invoice_Num                   => $actual->{mv_order_number},

The x_Invoice_Num is not being sent, since the mv_order_number is not 
available yet during the authorization.
Any suggestion on another value that needs to be used - maybe 
mv_transaction_id ?

Thanks,
Steve Graham
