I got an error about a missing expiration date until I entered a bogus
one.  It went through just fine that way.  Just thought I'd mention
it.

Just for clarification for others, this seems to be order_id, not orderid.

>   auth_code='authcode_issued_at_sale',

I didn't include an auth_code and it processed fine.

Thanks again for your help.
