=head1 Interchange Ezic Support
Vend::Payment::Ezic
=head1 SYNOPSIS
&charge=ezic
or
[charge mode=ezic param1=value1 param2=value2]
=head1 PREREQUISITES
Net::SSLeay
or
LWP::UserAgent and Crypt::SSLeay
Only one of these need be present and working.
=head1 DESCRIPTION
The Vend::Payment::Ezic module implements the ezic() routine
for use with Interchange. It is compatible on a call level with the other
Interchange payment modules.
To enable this module, place this directive in C<interchange.cfg>:
Require module Vend::Payment::Ezic
This I<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 C<gateway> parameter must be set
to C<ezic>. To make it the default payment gateway for all credit
card transactions in a specific catalog, you can set in C<catalog.cfg>:
Variable MV_PAYMENT_MODE ezic
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 C<id> parameter would
be specified by:
[charge mode=ezic id=YourEzicID]
or
Route ezic id YourEzicID
or
Variable MV_PAYMENT_ID YourEzicID
The active settings are:
=over 4
=item id
Your 12-digit EziC account number, supplied by EziC when you sign up.
Global parameter is MV_PAYMENT_ID.
=item site_id
A valid "site id", as configured in the EziC control panel. This controls
which templates are used for email receipts. Global parameter is MV_PAYMENT_REFERER.
=item 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)
=item remap
This remaps the form variable names to the ones needed by EziC. See
the C<Payment Settings> heading in the Interchange documentation for use.
=back
=head2 Troubleshooting
Try the instructions above, then enable test mode in the EziC control panel.
A test order should complete.
Disable test mode, then test in various Authorize.net 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:
=over 4
=item *
Make sure you "Require"d the module in interchange.cfg:
Require module Vend::Payment::Ezic
=item *
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).
=item *
Check the error logs, both catalog and global.
=item *
Make sure you set your payment parameters properly.
=item *
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.
=item *
If all else fails, Red Hat and other consultants are available to help
with integration for a fee.

=head1 BUGS
There is actually nothing *in* Vend::Payment::Ezic. It changes packages
to Vend::Payment and places things there.
