Ubuntu Manpage: Vend::Payment::PRI - Interchange PRI Support

NAME

       Vend::Payment::PRI - Interchange PRI Support

SYNOPSIS

           &charge=PRI

               or

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

PREREQUISITES

         Net::SSLeay

           or

         LWP::UserAgent and Crypt::SSLeay

       Only one of these need be present and working.

DESCRIPTION

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.

To enable this module, place this directive in "interchange.cfg":

Require module Vend::Payment::PRI

This 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 "gateway" parameter must be set to "PRI". To make it the default
payment gateway for all credit card transactions in a specific catalog, you can set in "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 "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:

Variable MV_PAYMENT_MODE "__MV_PAYMENT_MODE__"
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:

MV_PAYMENT_MODE PRI Payment
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:

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.

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.

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. Do not use this mode if you have a busy catalog. PRI might reject orders as duplicates if two people try to checkout at the same time.

2. A "2" in the pri_refid_mode instructs interchange to use the users
session_id as the value. This is the recommended mode.

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.

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

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_MODE to a value of 1,2 or 3 then
do your testing. Once everything is working correctly, simply set PRI_TEST_MODE to 0 and restart
interchange. Your now live.

Testing has 3 modes. (1,2,3) (live mode is 0) You set the mode with the PRI_TEST_MODE variable in
variable.txt or directly in your catalog.cfg file. The modes are as follows.

1) Use PRI_TEST_ID and PRI_TEST_REGKEY values. Send information to PRI and receive result from PRI.
To generate errors in this mode, simply enter invalid data and PRI should reject it with an error.

2) Generate a declined order internally. Does not send data to PRI. This mode is convenient if you
want to do some testing and do not want to send any data to PRI. It's also a good way to track down
errors.

3) Generate a successful sale internally. Does not send data to PRI. This mode is convenient if you
want to see if everything works before sending test data to PRI.

A good way to test this module is to set PRI_TEST_MODE to 3, then 2, then 1, then 0 and make sure
your catalog handles all situations correctly.

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.

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

https://webservices.primerchants.com/billing/TransactionCentral/processCC.asp?

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

Troubleshooting
If nothing works:

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

Require module Vend::Payment::PRI

• 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).

• Check the error logs, both catalog and global.

• Make sure you set your account ID properly.

• 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.

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

BUGS

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

VERSION HISTORY

       05-24-2004 - Version 1.0

       09-06-2004 -.Version 1.1
         Added testing mode support.       Changed default refid to mode 2.       Fixed bug where PRI.pm would
       not recognize a successful transaction with a mix of digits and letters.  Now checks for "Declined",
       <space> or <null> to determine declined transaction, all others succeed.       Cleaned up some code.
