=head1 NAME

Vend::Payment::BusinessOnlinePayment - Interchange wrapper for Business::OnlinePayment

=head1 SYNOPSIS

    &charge=onlinepayment

        or

    [charge mode=onlinepayment param1=value1 param2=value2]

=head1 PREREQUISITES

  Business::OnlinePayment
  Business::OnlinePayment:: gateway module

  See L<http://www.420.am/business-onlinepayment/> or 
  L<http://search.cpan.org/search?query=Business%3A%3AOnlinePayment&mode=module>

=head1 DESCRIPTION

This is a wrapper around Business::OnlinePayment for Interchange.

The Vend::Payment::BusinessOnlinePayment module implements the onlinepayment()
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 another gateway to a Business::OnlinePayment supported
gateway (or between different Business::OnlinePayment gateways) with a few
configuration file changes.

Business::OnlinePayment is a set of related Perl modules for processing online
payments (credit cards, electronic checks, and other payment systems).  It
provides a consistant interface for processing online payments, regardless of
the gateway backend being used, in the same way that DBI provides an consistant
interface to different databases.

See L<http://www.420.am/business-onlinepayment/> for more information and
supported gateways.

It is hoped that a future version of Interchange will do all credit card
processing through Business::OnlinePayment, but this is my no means
guaranteed and the timeframe is unknown.  Think ALSA somewhere around
Linux 2.2 and you've got the general idea.

Currently this module is recommended for people with gateway processors
unsupported by a native Interchange Vend::Payment:: module and for the
adventurous.

=head1 USAGE

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

    Require module Vend::Payment::BusinessOnlinePayment

This I<must> be in interchange.cfg or a file included from it.

The mode can be named anything, but the C<gateway> parameter must be set
to C<onlinepayment>. 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  onlinepayment

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<setting> parameter would
be specified by:

    [charge mode=onlinepayment setting=value]

or

    Route onlinepayment setting value

or 

    Variable MV_PAYMENT_SETTING      value

The following settings are available:

=over 4

=item processor

Your Business::OnlinePayment processor.

=item id

Your Business::OnlinePayment login.

=item secret

Your Busienss::OnlinePayment password.

=item transaction

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

    Interchange         Business::OnlinePayment
    ----------------    -----------------------
        auth            Authorization Only
        return          Credit
        reverse
        sale            Normal Authorization
        settle          Post Authorization
        void            Void

=item test

Set this true if you wish to operate in test mode.  Make sure to verify
that your specific Business::OnlinePayment:: gateway module supports a
test mode.

=back

In addition, any other processor options are passed to your gateway.  See
the documentation for your specific Business::OnlinePayment:: gateway module
for details on what options are required, if any.
