=head1 NAME

Interchange Protx Direct payment system interface

=head1 PREREQUISITES

Net::SSLeay

or

LWP::UserAgent and Crypt::SSLeay

wget - a recent version built with SSL and supporting the 'connect' timeout function.

=head1 QUICK START SUMMARY

1. Call this module in interchange.cfg with:

Require module Vend::Payment::Protx2

2. Add into products/variable.txt (tab separated):

MV_PAYMENT_MODE protx

3. Add a new route into catalog.cfg (options for the last entry in parentheses):

Route protx id YourProtxID

Route protx host ukvps.protx.com (ukvpstest.protx.com)

Route protx currency GBP (USD, EUR, others, defaults to GBP)

Route protx txtype PAYMENT (AUTHENTICATE, DEFERRED)

Route protx available yes (no, empty)

Route protx logzero yes (no, empty)

Route protx double_pay yes (no, empty)

Route protx logdir "path/to/log/dir"

Route protx protxlog yes (no, empty)

Route protx applyavscv2 '0': if enabled then check, and if rules apply use.

'1': force checks even if not enabled; if rules apply use.

'2': force NO checks even if enabled on account.

'3': force checks even if not enabled; do NOT apply rules.

Route protx giftaidpayment 0 (1 to donate tax to Gift Aid)

or put these vars into products/variable.txt instead:

MV_PAYMENT_ID YourProtxID Payment

MV_PAYMENT_MODE protx Payment

MV_PAYMENT_HOST ukvps.protx.com Payment

MV_PAYMENT_CURRENCY GBP Payment

and the rest as above.

4. Create a new locale setting for en_UK as noted in "item currency" below, and copy the

public space interchange/en_US/ directory to a new interchange/en_UK/ one. Ensure that any

other locales you might use have a correctly named directory as well. Ensure that this locale

is found in your version of locale.txt (and set up UK as opposed to US language strings to taste).

5. Create entry boxes on your checkout page for: 'mv_credit_card_issue_number', 'mv_credit_card_start_month',

'mv_credit_card_start_year', 'mv_credit_card_type', and optionally 'mv_credit_card_cvv2'.

=head1 DESCRIPTION

The Vend::Payment::Protx module implements the Protx() routine for use with

Interchange. It is not compatible on a call level with the other Interchange

payment modules - Protx does things rather differently. We need to save four of

the returned codes for re-use when doing a RELEASE, REPEAT, or REFUND.

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

Require module Vend::Payment::Protx2

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

Make sure CreditCardAuto is off (default in Interchange demos).

Note that the Protx 'Direct' system is the only one which leaves the customer on

your own site and takes payment in real time. Their other systems, eg Terminal

or Server, do not require this module.

Note also that Maestro cards can only be taken by the 3DSecure version of this module, not by this

version, as Mastercard have decreed that Maestro cards will no longer be accepted without 3DSecure.

While PREAUTH is still in this module, it is scheduled to be dropped on the 1st August 2007 or shortly

thereafter, and is only here as a backup during the changeover to AUTHENTICATE.

=head2 The active settings

The module uses several of the standard settings from the Interchange payment routes.

Any such setting, as a general rule, is obtained first from the tag/call options on

a page, then from an Interchange order Route named for the mode in catalog.cfg,

then a default global payment variable in products/variable.txt, and finally in

some cases a default will be hard-coded into the module.

=over

=item Mode

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

to C<protx>. 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 protx

or in variable.txt:

MV_PAYMENT_MODE protx (tab separated)

if you want this to cooperate with other payment systems, eg PaypalExpress, then see

the documentation that comes with that system - it should be fully explained there (essentially, you

don't run the charge route from profiles.order but from log_transaction).

=item id

Your Protx vendor ID, supplied by Protx when you sign up. Various ways to state this:

in variable.txt:

MV_PAYMENT_ID YourProtxID Payment

or in catalog.cfg either of:

Route protx id YourProtxID

Variable MV_PAYMENT_ID YourProtxID

=item txtype

The transaction type is one of: PAYMENT, AUTHENTICATE or DEFERRED for an initial purchase

through the catalogue, and then can be one of: REFUND, RELEASE, REPEAT for payment

operations through the virtual terminal.

The transaction type is taken firstly from a dynamic variable in the page, meant

primarily for use with the 'virtual payment terminal', viz: 'transtype' in a select box

though this could usefully be taken from a possible entry in the products database

if you have different products to be sold on different terms; then falling back to

a 'Route txtype AUTHENTICATE' entry in catalog.cfg; then falling back to a global

variable in variable.txt, eg 'MV_PAYMENT_TXTYPE AUTHENTICATE Payment'; and finally

defaulting to 'PAYMENT' hard-coded into the module. This variable is returned to

the module and logged using the value returned from Protx, rather than a value from

the page which possibly may not exist.

=item available

If 'yes', then the module will check that the gateway is responding before sending the transaction.

If it fails to respond within 9 seconds, then the module will go 'off line' and log the transaction

as though this module had not been called. It will also log the txtype as 'OFFLINE' so that you

know you have to put the transaction through manually later (you will need to capture the card

number to do this). The point of this is that your customer has the transaction done and dusted,

rather than being told to 'try again later' and leaving for ever. If not explicitly 'yes',

defaults to 'no'. NB: if you set this to 'yes', then add into the etc/report that is sent to you:

Txtype = [calc]($Session->{payment_result} || {})->{TxType};[/calc]. Note that you need to have

a recent version of wget which supports '--connect-timeout' to run this check. Note also that,

as this transaction has not been logged anywhere on the Protx server, you cannot use their

terminal to process it. You must use the PTIPM which includes a function for this purpose; ie,

it updates the existing order number with the new payment information returned from Protx. Note

further that if you have Protx set up to require the CV2 value, then the PTIPM will disable

CV2 checking at run-time by default for such a transaction (logging the CV2 value breaks Visa/MC

rules and so it can't be legally available for this process).

=item logzero

If 'yes', then the module will log a transaction even if the amount sent is zero (which the

gateway would normally reject). The point of this is to allow a zero amount in the middle of a

subscription billing series for audit purposes. If not explicitly 'yes', defaults to 'no'.

Note: this is only useful if you are using an invoicing system or the Payment Terminal, both of which

by-pass the normal IC processes. IC will allow an item to be processed at zero total price but simply

bypasses the gateway when doing so.

=item logempty

If 'yes, then if the response from Protx is read as empty (ie, zero bytes) the result is forced to

'success' and the transaction logged as though the customer has paid. There are two markers set to

warn of this:

$Session->{payment_result}{TxType} will be NULL,

$Session->{payment_result}{StatusDetail} will be: 'UNKNOWN status - check with Protx before dispatching goods'

and you should include these into the report emailed to you.

=item card_type

Protx requires that the card type be sent. Valid types are: VISA, MC, AMEX, DELTA, SOLO, UKE,

JCB, DINERS (UKE is Visa Electron issued in the UK). MAESTRO is no longer accepted without 3DSecure.

This may optionally be determined by the module using regexes, or you may use a select box on the page.

If there is an error in the regex match in this module due to a change in card ranges or some other

fault, then Protx will refuse the transaction and return an error message to the page. Using a select

box on the page automatically overrides use of the internal option. In the interests of robust

reliability it is *strongly* recommended that you use a select box.

You may display a select box on the checkout page like so:

<select name="mv_credit_card_type">

[loop

option=mv_credit_card_type

acclist=1

list=|

VISA=Visa,

MC=MasterCard,

SOLO=Solo,

DELTA=Delta,

AMEX=Amex,

UKE=Electron,

JCB=JCB,

DINERS=Diners

|

]

<option value="[loop-code]">[loop-param label]</option>

[/loop]

</select>

=item currency

Protx requires that a currency code be sent, using the 3 letter ISO standard,

eg, GBP, EUR, USD. The value is taken firstly from either a page setting or a

possible value in the products database, viz 'iso_currency_code'; then falling back

to the locale setting - for this you need to add to locale.txt:

code en_UK en_EUR en_US

iso_currency_code GBP EUR USD

It then falls back to a 'Route protx currency EUR' type entry in catalog.cfg;

then falls back to a global variable (eg MV_PAYMENT_CURRENCY EUR Payment); and

finally defaults to GBP hard-coded into the module. This variable is returned to

the module and logged using the value returned from Protx, rather than a value from

the page which possibly may not exist.

=item cvv2

This is sent to Protx as mv_credit_card_cvv2. Put this on the checkout page:

CVV2: <input type=text name=mv_credit_card_cvv2 value='' size=6>

but note that under PCI rules you must not log this value anywhere.

=item issue_number

This is used for some debit cards, and taken from an input box on the checkout page:

Card issue number: <input type=text name=mv_credit_card_issue_number value='' size=6>

=item StartDate

This is used for some debit cards, and is taken from select boxes on the

checkout page in a similar style to those for the card expiry date. The labels to be

used are: 'mv_credit_card_start_month', 'mv_credit_card_start_year'. Eg:

<select name="mv_credit_card_start_year">

[loop option=start_date_year lr=1 list=`

my $year = $Tag->time( '', { format => '%Y' }, '%Y' );

my $out = '';

for ($year - 7 .. $year) {

/\d\d(\d\d)/;

$last_two = $1;

$out .= "$last_two\t$_\n";

}

return $out;

`]

<option value="[loop-code]">[loop-pos 1]</option>

[/loop]

</select>

=item Log directory

To choose the directory used for logging both the Protx latency log and the double

payment safeguard record, set in catalog.cfg:

Route protx logdir "path/to/log/dir"

It must be relative to the catalog root directory if you have

NoAbsolute set for this catalog in interchange.cfg.

If logdir is not set, it defaults to the system /tmp.

A somewhat dangerous option allows the payment page to specify the

logdir in a form variable, like this:

<input type="hidden" name="logdir" value='your_choice_here'>

This allows an individual user to have his own logs in a shared hosting

environment. However, it also allows a creative end-user to create

arbitrary empty files or update timestamps of existing files.

Because of the potential for abuse, this option is not allowed unless you set

a special route variable indicating you want it:

Route protx logdir_from_user_allowed 1

=item Protx API v2.22 extra functions

ApplyAVSCV2 set to:

0 = If AVS/CV2 enabled then check them. If rules apply, use rules. (default)

1 = Force AVS/CV2 checks even if not enabled for the account. If rules apply, use rules.

2 = Force NO AVS/CV2 checks even if enabled on account.

3 = Force AVS/CV2 checks even if not enabled for the account but DON'T apply any rules.

You may pass this value from the page as 'applyavscv2' to override the payment route setting.

CustomerName: optional, may be different to the cardholder name

ContactFax: optional

GiftAidPayment: set to -

0 = This transaction is not a Gift Aid charitable donation(default)

1 = This payment is a Gift Aid charitable donation and the customer has AGREED to donate the tax.

You may pass this value from the page as 'giftaidpayment'

ClientIPAddress: will show in Protx reports, and they will attempt to Geo-locate the IP.

=item Encrypted email with card info

If you want to add the extra fields (issue no, start date) to the PGP message

emailed back to you, then set the following in catalog.cfg:

Variable<tab>MV_CREDIT_CARD_INFO_TEMPLATE Card type: {MV_CREDIT_CARD_TYPE}; Card no: {MV_CREDIT_CARD_NUMBER}; Expiry: {MV_CREDIT_CARD_EXP_MONTH}/{MV_CREDIT_CARD_EXP_YEAR}; Issue no: {MV_CREDIT_CARD_ISSUE_NUMBER}; StartDate: {MV_CREDIT_CARD_START_MONTH}/{MV_CREDIT_CARD_START_YEAR}

=item testing

The Protx test site is ukvpstest.protx.com, and their live site is

ukvps.protx.com. Enable one of these in MV_PAYMENT_HOST in variable.txt

(*without* any leading https://) or as 'Route protx host ukvpstest.protx.com' in

catalog.cfg.

=item methods

NB: Protx have removed PREAUTH from their protocol and replaced it with AUTHENTICATE/AUTHORISE.

An AUTHENTICATE will validate the card and store the card details on Protx's system for up to 90 days.

Against this you may AUTHORISE for any amount up to 115% of the original value.

A DEFERRED will place a shadow ('block') on the funds for seven days (or so, depending

on the acquiring bank). Against a DEFERRED you may do a RELEASE to settle the transaction.

A PAYMENT will take the funds immediately. Against a PAYMENT, you may do a

REFUND or REPEAT.

A RELEASE is performed to settle a DEFERRED. Payment of the originally specified

amount is guaranteed if the RELEASE is performed within the seven days for which

the card-holder's funds are 'blocked'.

A REFUND may be performed against a PAYMENT, RELEASE, AUTHORISE or REPEAT. It may be for a

partial amount or the entire amount, and may be repeated with several partial

REFUNDs so long as the total does not exceed the original amount.

A DIRECTREFUND sends funds from your registered bank account to the nominated credit card.

This does not need to refer to any previous transaction codes, and is useful if you need to

make a refund but the customer's card has changed or the original purchase was not made by card.

=back

=head2 Virtual Payment Terminal

This has now been split out from this module, and may be found as the rather pretentiously named

Payment Terminal Interchange Plug-in Module (PTIPM), also on http://kiwi.zolotek.net. The PTIPM

does refunds and repeats, directrefunds, and converts offline transactions to online ones. Being a

plugin to the Interchange Admin Panel it integrates these operations into your database.

=head1 TROUBLESHOOTING

Only the test card numbers given below will be successfully

authorised (all other card numbers will be declined).

VISA 4929 0000 0000 6

MASTERCARD 5404 0000 0000 0001

DELTA 4462000000000003

SOLO 6334900000000005 issue 1

DOMESTIC MAESTRO 5641 8200 0000 0005 issue 01 (should be rejected now)

AMEX 3742 0000 0000 004

ELECTRON 4917 3000 0000 0008

JCB 3569 9900 0000 0009

DINERS 3600 0000 0000 08

You'll also need to supply the following values for CV2, Billing Address Numbers and Billing Post Code

Numbers. These are the only values which will return as Matched on the test server. Any other values

will return a Not Matched on the test server.

CV2 123

Billing Address Numbers 88

Billing Post Code Numbers 412

If nothing works:

=over 4

=item *

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

Require module Vend::Payment::Protx2

=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 catalogue and global. Make sure you set your payment

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

<pre>

[calcn]

my $string = $Tag->uneval( { ref => $Session->{payment_result} });

$string =~ s/{/{\n/;

$string =~ s/,/,\n/g;

return $string;

[/calcn]

</pre>

That should show what happened.

=item *

If you have unexplained and unlogged errors then check you have allowed the new database fields to

be NULL. If MySQL tries to write to a field that is marked NOT NULL then it will fail silently.

=item *

If you have a PGP/GPG failure when placing an order through your catalogue

then this may cause the module to be immediately re-run. As the first run would

have been successful, meaning that both the basket and the credit card information

would have been emptied, the second run will fail. The likely error message within

the catalogue will be:

"Can't figure out credit card expiration". Fixing PGP/GPG will fix this error.

If you get the same error message within the Virtual Terminal, then you haven't

set the order route as noted above.

=item *

If all else fails, Zolotek and other consultants are available to help

with integration for a fee.
