Vend::Payment::PRI(3) 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]

or 

    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"'

    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).

  • 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.

BUGS

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

        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.
