It is compatible on a call level with the other Interchange payment modules. .PP To enable this module, place this directive in \f(CW\*(C`interchange.cfg\*(C'\fR: .PP .Vb 1 \& Require module Vend::Payment::Linkpoint .Ve .PP This \fImust\fR be in interchange.cfg or a file included from it. .PP Make sure CreditCardAuto is off (default in Interchange demos). .PP The mode can be named anything, but the \f(CW\*(C`gateway\*(C'\fR parameter must be set to \f(CW\*(C`linkpoint\*(C'\fR. To make it the default payment gateway for all credit card transactions in a specific catalog, you can set in \f(CW\*(C`catalog.cfg\*(C'\fR: .PP .Vb 1 \& Variable MV_PAYMENT_MODE linkpoint .Ve .PP 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 \f(CW\*(C`id\*(C'\fR parameter would be specified by: .PP .Vb 1 \& [charge mode=linkpoint id=YourLinkpointID] .Ve .PP or .PP .Vb 1 \& Route linkpoint id YourLinkpointID .Ve .PP or .PP .Vb 1 \& Variable MV_PAYMENT_ID YourLinkpointID .Ve .PP Required settings are \f(CW\*(C`id\*(C'\fR and \f(CW\*(C`keyfile\*(C'\fR. .PP The active settings are: .IP "host" 4 .IX Item "host" Your LinkPoint Secure Payment Gateway (\s-1LSPG\s0) hostname. Usually secure.linkpt.net (production) or staging.linkpt.net (testing). .IP "keyfile" 4 .IX Item "keyfile" File name of the merchant security certificate. This file should contain the \&\s-1RSA\s0 private key and the certificate, otherwise you get an error like \&\*(L"Unable to open/parse client certificate file.\*(R" .IP "id" 4 .IX Item "id" Store number assigned to your merchant account. .IP "transaction" 4 .IX Item "transaction" The type of transaction to be run. Valid values are: .Sp .Vb 5 \& Interchange Linkpoint \& \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \& auth PREAUTH \& sale SALE \& settle_prior POSTAUTH .Ve .Sp Default is \f(CW\*(C`sale\*(C'\fR. .IP "check_sub" 4 .IX Item "check_sub" Name of a Sub or GlobalSub to be called after the result hash has been received from LinkPoint. A reference to the modifiable result hash is passed into the subroutine, and it should return true (in the Perl truth sense) if its checks were successful, or false if not. .Sp This can come in handy since LinkPoint has no option to decline a charge when \s-1AVS\s0 or \s-1CVV\s0 data come back negative. .Sp If you want to fail based on a bad \s-1AVS/CVV\s0 check, make sure you're only doing an auth \*(-- \fBnot a sale\fR, or your customers would get charged on orders that fail the \s-1AVS/CVV\s0 check and never get logged in your system! .Sp Add the parameters like this: .Sp .Vb 1 \& Route linkpoint check_sub link_check .Ve .Sp This is a matching sample subroutine you could put in interchange.cfg: .Sp .Vb 10 \& GlobalSub <{r_avs}; \& my ($addr, $zip, $nothing, $cvv) = split m{}, $avs; \&#::logDebug("avs=$avs, addr=$addr zip=$zip banks=$nothing cvv=$cvv"); \& return 1 if $addr eq \*(AqY\*(Aq or $zip eq \*(AqY\*(Aq; \& return 1 if $addr eq \*(AqX\*(Aq and $zip eq \*(AqX\*(Aq; \& return 1 if $cvv =~ /^[MPSUX]$/; \& $result\->{MStatus} = \*(Aqfailure\*(Aq; \& if ($cvv eq \*(AqN\*(Aq || \*(Aq\*(Aq) { \& $result\->{r_error} = "The card security code you entered does not match. Additional failed attempts may hold your available funds."; \& } \& else { \& $result\->{r_error} = "The billing address you entered does not match the cardholder\*(Aqs billing address. Additional failed attempts may hold your available funds."; \& } \& } \& EOR .Ve .Sp That would work equally well as a Sub in catalog.cfg. It will succeed if either the address or zip is 'Y', or if both are unknown, or if the \s-1CVV\s0 matches or is unknown. If it fails, it sets the error message in the result hash. .Sp Of course you can use this sub to do any other post-processing you want as well. .SS "Troubleshooting" .IX Subsection "Troubleshooting" If nothing works: .IP "\(bu" 4 Make sure you \*(L"Require\*(R"d the module in interchange.cfg: .Sp .Vb 1 \& Require module Vend::Payment::Linkpoint .Ve .IP "\(bu" 4 Make sure lpperl (v3.0.012+) is installed and working. You can test to see whether your Perl thinks they are: .Sp .Vb 1 \& perl \-Mlpperl \-e \*(Aqprint "It works.\en"\*(Aq .Ve .Sp If it \*(L"It works.\*(R" and returns to the prompt you should be \s-1OK \s0(presuming they are in working order otherwise). .IP "\(bu" 4 Make sure curl is installed and working. Lpperl uses curl to contact Linkpoint. .IP "\(bu" 4 Check the error logs, both catalog and global. .IP "\(bu" 4 Make sure you set your payment parameters properly. .IP "\(bu" 4 Try an order, then put this code in a page: .Sp .Vb 8 \& \& [calc] \& my $string = $Tag\->uneval( { ref => $Session\->{payment_result} }); \& $string =~ s/{/{\en/; \& $string =~ s/,/,\en/g; \& return $string; \& [/calc] \& .Ve .Sp That should show what happened. .SH "BUGS" .IX Header "BUGS" There is actually nothing *in* Vend::Payment::Linkpoint. It changes packages to Vend::Payment and places things there. .SH "AUTHOR" .IX Header "AUTHOR" Stefan Hornburg (Racke) Ron Phipps
