ICS2

Interchange's support for the International Commerce Solutions  Payment Services Provider.

Synopsis

Prerequisites

or

Only one of the above options needs be present and working.

Description

The Vend::Payment::ICS2 module implements the ICS2() subroutine for use with Interchange.  It is compatible on a call level with the other Interchange payment modules.  In theory (and even usually in practise) you could switch from another payment module to ICS2 with a few configuration file changes.

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

This must be in interchange.cfg or a file included from it.

Make sure CreditCardAuto is off, which is the default in the Standard ecommerce demo.

The "mode" can be named anything, but the "gateway" parameter must be set to "ICS2".  To make it the default payment gateway for all credit card transactions in a specific website, you can set the following in catalog.cfg:

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 after the mode, then finally a default global payment Variable.  For example, the merchant_id parameter would be specified by:

or

or

A fully valid catalog.cfg entry to work with the Standard demo would be:

The variable.txt (see VariableDatabase) lines to work with the ICS2 module look like this (with tab-separated columns):

Settings

Name	Description
transaction	At this time, the ICS2 payment module only processes transactions of type "SALE".
test	To test, set ICS2_MODE to a true value (not 0 and not NULL) in your variable.txt file.  Your transactions will then be sent to the ICS test server.
generate_error	Read the ICS documentation to find out how to generate errors.  At this time, transactions ending in dollar amounts of 9 will decline, in 8 or 0 will succeed and 1-7 will get random errors.  For instance, $1.00 and $1.08 will succeed, $1.09 will decline and $1.01-$1.07 will result in random errors.

Troubleshooting

If nothing works:

• Make sure you Required the module in interchange.cfg:

  Require module Vend::Payment::ICS2

• 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 -le 'print "Available"'

  or

  perl -MLWP::UserAgent -MCrypt::SSLeay -le 'print "Available"'

  If either of the above prints "Available", and returns to the shell prompt, then you should be OK (presuming they are in working order otherwise).

  
  
• Check the local and global error log files.
  
  
• Make sure you set your payment parameters properly, including your account ID.
  
  

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

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

  That should show what happened.

  
  
• If all else fails, consultants are available to help with integration for a fee.

Notes

There is actually nothing in Vend::Payment::ICS2;  This module changes its package name to Vend::Payment and places things there.
