ProxyPay

Interchange's support for the Clear2Pay  Payment Services Provider's ProxyPay XML interface.

Synopsis

or

Prerequisites

or

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

Description

The Vend::Payment::ProxyPay module implements the proxypay() 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 ProxyPay 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 "proxypay".  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:

Settings

Name	Description
id	Your ProxyPay Merchant ID, supplied by the organisation who issues you access to their ProxyPay gateway.  The variable is MV_PAYMENT_ID.
password	The ProxyPay Password to verify who you are.  The variable is MV_PAYMENT_PASSWORD.
transaction	Interchange ProxyPay auth PreAuth return Refund reverse Refund sale PreAuth + Capture (requires two separate requests) settle Capture void Cancel The default is "sale". The variable is MV_PAYMENT_TRANSACTION.
submit_url	The ProxyPay URI to connect to.  The variable is MV_PAYMENT_SUBMIT_URL.
remap	This remaps the form variable names to the ones needed by ProxyPay.

Troubleshooting

If nothing works:

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

  Require module Vend::Payment::ProxyPay

• 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 merchant ID and password.
  
  

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