Ezic

Interchange's support for the Ezic  Payment Services Provider.

Synopsis

or

Prerequisites

or

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

Description

The Vend::Payment::Ezic module implements the ezic() 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 Ezic 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 "ezic".  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

Settings

Name	Description
id	A valid "site id", as configured in the Ezic control panel.  This controls which templates are used for email receipts.  The variable is MV_PAYMENT_ID.
transaction	The type of transaction to be run.  Valid values are: Interchange Ezic auth A (Auth) return C (Credit) reverse R (Refund) sale S (Sale) settle D (Capture) void R (Refund)
remap	This remaps the form variable names to the ones needed by Ezic.

Troubleshooting

Try the instructions above, then enable test mode in the Ezic control panel.  A test order should complete.

Disable test mode and then test in various Ezic error modes by using the credit card number configured in the "setup" section of the Ezic control panel.  In the Documentation section of that control panel, an up to date list of amounts that generate different error responses is provided.  Errors should appear in [data session payment_error].

If nothing works:

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

  Require module Vend::Payment::Ezic

• 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.
  
  

• 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::Ezic;  This module changes its package name to Vend::Payment and places things there.
