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.

       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]

       or

           Route trustcommerce id YourTrustCommerceID

       or

           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.
