NAME

Vend::Payment::TCLink - Interchange TrustCommerce Support

SYNOPSIS

    &charge=trustcommerce
 
        or
 
    [charge mode=trustcommerce param1=value1 param2=value2]

PREREQUISITES

    Net::TCLink

http://www.trustcommerce.com/tclink.html and CPAN both have this module, which actually does the bulk of the work. All that Vend::Payment::TCLink does is to massage the payment data between Interchange and Net::TCLink.

DESCRIPTION

The Vend::Payment::TCLink module implements the trustcommerce() 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 CyberCash to TrustCommerce with a few configuration file changes.

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

    Require module Vend::Payment::TCLink

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

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

The mode can be named anything, but the "gateway" parameter must be set to "trustcommerce". 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 trustcommerce

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=trustcommerce id=YourTrustCommerceID]

    Route trustcommerce id YourTrustCommerceID

    Variable TRUSTCOMMERCE_ID YourTrustCommerceID

The active settings are:

id

Your TrustCommerce customer ID, supplied by TrustCommerce when you sign up. Global parameter is TRUSTCOMMERCE_ID.

secret

Your TrustCommerce customer password, supplied by TrustCommerce when you sign up. Global parameter is TRUSTCOMMERCE_SECRET.

transaction

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

    Interchange         TrustCommerce
    ----------------    -----------------
        auth            preauth
        return          credit
        sale            sale
        settle          postauth

Global parameter is TRUSTCOMMERCE_ACTION.

avs

Whether AVS (Address Verification System) is enabled. Valid values are "y" for enabled and "n" for disabled. Global parameter is TRUSTCOMMERCE_AVS.

remap

This remaps the form variable names to the ones needed by TrustCommerce. See the "Payment Settings" heading in the Interchange documentation for use.

test

Set this to "TRUE" if you wish to operate in test mode, i.e. set the TrustCommerce "demo" query paramter to TRUE.

Examples:

    Route trustcommerce test TRUE
        or
    Variable TRUSTCOMMERCE_TEST TRUE
        or 
    [charge mode=trustcommerce test=TRUE]

Troubleshooting

Try the instructions above, then enable test mode. A test order should complete.

Disable test mode, then test in various TrustCommerce error modes by using the credit card number 4222 2222 2222 2222.

Then try a sale with the card number "4111 1111 1111 1111" and a valid expiration date. The sale should be denied, and the reason should be in [data session payment_error].

If nothing works:

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

    Require module Vend::Payment::TrustCommerce

Make sure Net::TCLink is installed and working. You can test to see whether your Perl thinks they are:
```
    perl -MNet::TCLink -e 'print "It works.\n"'
    
```
If it "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 payment parameters 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, TrustCommerce consultants are available to help you out.

BUGS

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