Vend::Payment::PRI - Interchange PRI Support




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


  LWP::UserAgent and Crypt::SSLeay

Only one of these need be present and working.


The Vend::Payment::PRI module implements the PRI() routine for using
Payment Resources International payment services 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 PRI
with a few configuration file changes.

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

    Require module Vend::Payment::PRI

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

NOTE: 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<PRI>. 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  PRI

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=PRI id=YourPRIID]


    Route PRI id YourPRIID

or with only PRI as a payment provider

    Variable MV_PAYMENT_ID      YourPRIID

A fully valid catalog.cfg entry to work with the standard demo would be:

		Route  PRI      id          "__PRI_ID__"
		Route  PRI      regkey      "__PRI_REGKEY__"
		Route  PRI      test_id     "__PRI_TEST_ID__"
		Route  PRI      test_regkey "__PRI_TEST_REGKEY__"
		Route  PRI      test_mode   "__PRI_TEST_MODE__"
		Route  PRI      refid_mode  "__PRI_REFID_MODE__"
A fully valid variable.txt entry to work with the PRI module would be:

		PRI_ID	your_pri_id	Payment
		PRI_REGKEY	your_pri_regkey	Payment
		PRI_TEST_ID	your_pri_test_id	Payment
		PRI_TEST_REGKEY	your_pri_test_regkey	Payment
		PRI_TEST_MODE	1	Payment
		PRI_REFID_MODE	1	Payment

The active settings are:

=over 4

=item id

PRI will supply you with both a test id and production id.  Enter both of these numbers into the the variables above.  You do not need your production id to test. 

=item regkey

PRI will supply you with both a test regkey and production regkey.  Enter both of these numbers into the the variables above.  You do not need your production regkey to test. 

=item refid

The PRI interface allows (requires) a field called REFID.  This field is stored along with the transaction on the PRI server and allows your to do quick searches for transactions if this number has meaning.  There are three possible values for the PRI_REFID_MODE variable.  1,2 or any other character or null.  

	1.  A "1" in the pri_refid_mode instructs interchange to read the current
	order number in $Variable->{MV_ORDER_COUNTER_FILE} or "etc/order.number",
	increment it by one and use that.  This is the recommended mode.
	2. A "2" in the pri_refid_mode instructs interchange to use the users
	session_id as the value.
	3. Anything other than a 1 or 2 instructs interchange to generate a unique
	number from the unix date command and use that.  The number format is Day of
	year, Hours, Minutes, Seconds.  Example for Jan 1, at 1:00:30 is 001130030.

=item transaction

At this time the PRI payment module only processes transactions of type SALE.

=item test

Testing with PRI is straight forward.  At this time (2004-05-15), PRI uses the same server for both development and production.  The only difference is the account used.  Some accounts are flagged as TEST accounts and others are live.  When you first sign up with PRI they will supply you a test account and test Registration Key to use.  Enter those numbers in the PRI_ID, PRI_REGKEY (production) and PRI_TEST_ID, PRI_TEST_REGKEY (test) variables.  Set the PRI_TEST_MORE to a value of 1 then do your testing.  Once everything is working correctly, simply set PRI_TEST_MODE to 0 and restart interchange.  Your now live.

=item generate_error

To generate errors in test mode (while using your test ID and regkey) simply enter transactions with bad data and see what happens.  PRI will supply you with a list of test credit card numbers and amounts that they are good for. 

=over 4

=item submit_url

PRI uses different URL's depending on what type of transaction you are requesting, Sale, Reccuring, Void etc..  The default URL for single sale transactions is


At this time, this is the only URL supported by this PRI module

=head2 Troubleshooting

If nothing works:

=over 4

=item *

Make sure you "Require"d the module in interchange.cfg:

    Require module Vend::Payment::PRI

=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"'


    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 account ID properly.  

=item *

Try an order, then put this code in a page:

        my $string = $Tag->uneval( { ref => $Session->{payment_result} });
        $string =~ s/{/{\n/;
        $string =~ s/,/,\n/g;
        return $string;

That should show what happened.

=item *

If all else fails, consultants are available to help with integration for a fee.

=head1 BUGS

There is actually nothing *in* Vend::Payment::PRI. It changes packages
to Vend::Payment and places things there.
