request

    my $xml = $pxpay->request_xml($args);
    my $rtn = $pxpay->request($args);

request and parse the response XML into HASHREF. sample:

    $VAR1 = \{
        'URI' => 'https://sec2.paymentexpress.com/pxpay/pxpay.aspx?userid=
TestAccount&request=v51flwn7rvSNcbY86uRMdJ74XB2gHd8ZY-WHqyEYoPm9xd1ROXX00pXYkkuk
dleLlS402E65EjOSCkrqvmAsZUWRCck8RkmIJcRLvG0KZLi7PQRBfpIQ0wzKwdHGKvBCpqhRH6Tx-w93
MRYsP0ThOK4btgTneR_hGEk0supyLeE1taNWCkyFj8KX7rzZ9ncdWRlmciNBsiV4zX4DQ_7Poi9qiblI

hJHB96kjBziu3GyGBvaGfsosNodT3-wyM29A5M-Z62ITkno6JUA6H4',
        'valid' => '1'
    };

Usually you need redirect to the $rtn->{URI} when valid is 1

result

    my $xml = $pxpay->result_xml($ResponseCode);
    my $rtn = $pxpay->result($ResponseCode);
    if ( exists $rtn->{valid} and $rtn->{valid} == 1 ) {
        print "Transaction Success!\n";
    } else {
        print "Transaction Failed!\n";
    }

PxPay will POST to your UrlSuccess (or UrlFail) when you finish the transaction (or click Cancel button). the POST would contain a param result which you can request to get the transaction status.

TIPS

I need params in UrlSuccess

For example, you want your UrlSuccess to be 'http://mysite.com/cgi-bin/cart.cgi?cart_id=ABC'.

you need write the request like:

    my $rtn = $pxpay->request(
        # others
        UrlSuccess => 'http://mysite.com/cgi-bin/cart.cgi',
        TxnData1 => 'ABC',
    );

and you can get the TxnData1 in

    my $rtn = $pxpay->result($ResponseCode);
    my $cart_id = $rtn->{TxnData1}
