=head1 NAME

Vend::Payment::PSiGate - Interchange PSiGate Support

=head1 SYNOPSIS

    &charge=psigate

        or

    [charge mode=psigate 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::PSiGate module implements the psigate() routine
for use with Interchange. It is compatible on a call level with the other
Interchange payment modules -- in theory (and even usually in practice) you
could switch from CyberCash to PSiGate.com with a few configuration
file changes.

To enable this module, place this directive in C<interchange.cfg>:

    Require module Vend::Payment::PSiGate

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<psigate>. 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  psigate

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=psigate id=YourPSiGateMerchantID]

or

    Route psigate id YourPSiGateMerchantID

or

    Variable MV_PAYMENT_ID      YourPSiGateMerchantID

The active settings are:

=over 4

=item id

Your PSiGate.com account ID, supplied by PSiGate.com when you sign up.
Global parameter is MV_PAYMENT_ID.

=item referer

A valid referering url (match this with your setting on PSiGate).
Global parameter is MV_PAYMENT_REFERER.

=item transaction

The type of transaction to be run. Valid values are:

    Interchange         PSiGate               Note
    ----------------    -----------------     ---------
        auth            '1',                  PreAuth
        sale            '0',                  Sale
        settle          '2',                  PostAuth
        void            '9',                  Void

=item remap

This remaps the form variable names to the ones needed by PSiGate. See
the C<Payment Settings> heading in the Interchange documentation for use.

=item test

Set this to C<TRUE> if you wish to operate in test mode, i.e. set the 
PSiGate
C<x_Test_Request> query paramter to TRUE.i

Examples:

    Route    psigate  test  TRUE
        or
    Variable   MV_PAYMENT_TEST   TRUE
        or
    [charge mode=psigate test=TRUE]

=back

=head2 Troubleshooting

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

Disable test mode, then test in various PSiGate error modes by
using the credit card number 4111 1111 1111 1111.

Then try a sale with the card number C<4111 1111 1111 1111>
and a valid expiration date. The sale should be denied, and the reason 
should
be 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::PSiGate

=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::PSiGate. It changes packages
to Vend::Payment and places things there.
