The MCVE libraries are available free at http://www.mcve.com/
DESCRIPTION
MCVE, Mainstreet Credit Verification Engine is a high performance software application designed to provide quality, in-house, Credit Card
processing FROM Linux, FreeBSD, OpenBSD, IBM AIX, Sun Solaris, SCO OpenServer/UnixWare, and Mac OS X platforms to established clearing
houses. The MCVE C & Perl library software can be downloaded free of charge from http://mcve.com. This module was developed and tested
with the server software installed on HotConnect.net (http://www.hotconnect.net). Hot Connect, Inc. is an Interchange friendly Web
Hosting, E-Commerce, and Internet Services company.
The Vend::Payment::MCVE module implements the mcve() routine for use with Interchange. It is compatible on a call level with the other
Interchange payment modules.
To enable this module, place this directive in "interchange.cfg":
Require module Vend::Payment::MCVE
This must be in interchange.cfg or a file included from it.
Make sure CreditCardAuto is off (default in Interchange demos).
The mode can be named anything, but the "gateway" parameter must be set to "mcve". To make it the default payment gateway for all credit
card transactions in a specific catalog, you can set in "catalog.cfg":
Variable MV_PAYMENT_MODE mcve
It uses several of the standard settings from Interchange payment. Any time we speak of a setting, it is obtained either first from the
tag/call options, then from an Interchange order Route named for the mode, then finally a default global payment variable, For example, the
"id" parameter would be specified by:
[charge mode=mcve name=mcve_configname]
or
Route mcve name mcve_configname
or
Variable MV_PAYMENT_NAME mcve_configname
The active settings are:
Variable MV_PAYMENT_MODE mcve
Variable MV_PAYMENT_NAME mcve_username
Variable MV_PAYMENT_PASSWD mcve_password
Variable MV_PAYMENT_HOST sv1.carlc.com
Variable MV_PAYMENT_PORT 8333
Variable MV_PAYMENT_COUNTER etc/mcve_id.counter
Variable MV_PAYMENT_COUNTER_START 100
Variable MV_PAYMENT_SALE_ON_AUTH 1
Variable MV_PAYMENT_NO_SALE_BAD_AVS 0
Variable MV_PAYMENT_NO_SALE_BAD_CVV2 0
Variable MV_PAYMENT_SUCCESS_ON_ANY 0
name
Your MCVE configuration username, set up when MCVE was configured/installed on the machine. Global parameter is MV_PAYMENT_NAME.
no_sale_bad_avs
Normally Interchange charge modules do an authorization, and if successful, do a sale. This module is configurable for a different
models, where transactions are not automatically saled.
sale_on_auth
The storekeeper may not wish to sale a transaction if the AVS is bad.
success_on_any
Alternatively the storekeeper may wish to cause any transaction to appear to be a successful sale. The storekeeper would have to
contact buyers with bad credit card information and manually redo the sale. The motivation is to make sure no one attempts a sale and
gives up for any reason. This mode of operation, set with MV_PAYMENT_SUCCESS_ON_ANY is not commonly used.
transaction
The type of transaction to be run. Valid values are:
Interchange mode MCVE mode
---------------- -----------------
auth auth
sale sale
Not supported yet:
return return
reverse reverse
void void
counter, counter_start
Currently this is not being used, and Interchange is generating id's.
Route mcve counter etc/mcve_id.counter
Route mcve counter_start 100
Troubleshooting
Try the instructions above, with a test credit card number from your payment processor.
Then try a sale with the card number "4111 1111 1111 1111" and a valid expiration date. The sale should be denied, and the reason should be
in [data session payment_error].
If nothing works:
Make sure you "Require"d the module in interchange.cfg:
Require module Vend::Payment::MCVE
Make sure MCVE is installed and working.
Check the error logs, both catalog and global.
Make sure you set your payment parameters properly.
Try an order, then put this code in a page:
[calc]
$Tag->uneval( { ref => $Session->{payment_result} );
[/calc]
That should show what happened.
BUGS
There is actually nothing *in* Vend::Payment::MCVE. It changes packages to Vend::Payment and places things there.
