NAME

Vend::Payment::iTransact - Interchange iTransact Support

SYNOPSIS

    &charge=itransact
 
        or
 
    [charge mode=itransact param1=value1 param2=value2]

PREREQUISITES

  Net::SSLeay
 
    or
  
  LWP::UserAgent and Crypt::SSLeay

Only one of these need be present and working.

DESCRIPTION

The Vend::Payment::iTransact module implements the itransact() routine for use with Interchange. It is compatible on a call level with the other Interchange payment modules -- in theory (and even usually in practice) you could switch from CyberCash to iTransact with a few configuration file changes.

To enable this module, place this directive in "interchange.cfg":

    Require module Vend::Payment::iTransact

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 "itransact". 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  itransact

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=itransact id=YouriTransact]

    Route itransact id YouriTransactID

    Variable MV_PAYMENT_ID      YouriTransactID

The active settings are:

id: Your iTransact account ID, supplied by iTransact when you sign up. Global parameter is MV_PAYMENT_ID.
home_page: The internet address of your site. Defaults to "http://__SERVER_NAME__" if not set. Global parameter is MV_PAYMENT_HOME_PAGE.
remap: This remaps the form variable names to the ones needed by iTransact. See the "Payment Settings" heading in the Interchange documentation for use.

Troubleshooting

Try the instructions above, then enable test mode. A test order should complete.

Then move to live mode and 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::iTransact

Make sure either Net::SSLeay or Crypt::SSLeay and LWP::UserAgent are installed and working. You can test to see whether your Perl thinks they are:
```
    perl -MNet::SSLeay -e 'print "It works\n"'
    
```
or
```
    perl -MLWP::UserAgent -MCrypt::SSLeay -e 'print "It works\n"'
    
```
If either one prints "It works." and returns to the prompt you should be OK (presuming they are in working order otherwise).
Check the error logs, both catalog and global.
Make sure you set your account ID properly.

Try an order, then put this code in a page:

    <XMP>
    [calc]
        my $string = $Tag->uneval( { ref => $Session->{payment_result} });
        $string =~ s/{/{\n/;
        $string =~ s/,/,\n/g;
        return $string;
    [/calc]
    </XMP>

That should show what happened.

If all else fails, consultants are available to help with integration for a fee. See http://www.icdevgroup.org/

BUGS

There is actually nothing *in* Vend::Payment::iTransact. It changes packages to Vend::Payment and places things there.
