Skipjack

Interchange's support for the Skipjack  Payment Services Provider.

Synopsis

Prerequisites

or

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

Description

The Vend::Payment::Skipjack module implements the skipjack() 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 Skipjack 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 "skipjack".  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 id parameter would be specified by:

or

or

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

Settings

Name	Description
id	Your account ID number, supplied by Skipjack when you sign up.  Use the supplied HTML Serial Numbers (Nova or Vital) while testing in development mode.  The variable is MV_PAYMENT_ID.
vendor	The developer ID of the system which interfaces with Skipjack.  The variable is MV_PAYMENT_VENDOR.
transaction	The type of transaction to be run.  Valid values are: Interchange Skipjack sale sale recurring recurring The default is "sale" If you want to submit a recurring charge, then you will have to ensure that the following Interchange values are set properly: Interchange variable Skipjack variable recurring_item rtItemNumber recurring_desc rtItemDescription recurring_start_date rtStartingDate recurring_frequency rtFrequency recurring_transactions rtTotalTransactions recurring_comment rtComment
test	If you set the "test" parameter, Interchange will remap some values and the URI for the transaction to point to the Skipjack test server.  It will return a valid transaction if all is working.
generate_error	To generate errors (in test mode only), set this parameter to one of the following values: Value Error generated number invalid credit card number. avs will succeed, but generate AVS message. exp expired card. id invalid Skipjack account? vendor invalid vendor?

The following settings should rarely be required, as the supplied defaults are usually correct: 

Name	Description
remap	This remaps the form variable names to the ones needed by Skipjack.
submit_url	The Skipjack URI to submit to.  The default is: https://www.skipjackic.com/scripts/evolvcc.dll?Authorize You can add the following to your catalog.cfg file while in development mode: Route  skipjack  submit_url  "https://developer.skipjackic.com/scripts/evolvcc.dll?Authorize"

Troubleshooting

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

Next, generate an error by posting a sale transaction with the following setup:

The failure message should be available in [data session payment_error].

If nothing works:

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

  Require module Vend::Payment::Skipjack

• 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 the 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.

Security considerations

Because this library may call an executable, you should ensure that no untrusted users have write permission on any of the system directories or Interchange software directories.

Notes

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