this code was give to me by the vendor, & when using it, it comes back from the server with an error saying it does not match what was sent?? any help would be greatly appreciated. This is the complete sample code: 
use LWP::UserAgent;
use Digest::SHA1  qw(sha1 sha1_hex sha1_base64);
 
$sourcekey = 'Your_source_key_here';
$pin = '1234';
$command = 'cc:sale';
$amount = '5.50';
$invoice = '123123';
 
# Generate Hash
$seed = rand();
$prehash = $command . ":" . $pin . ":" . $amount . ":" . $invoice . ":
+" . $seed;
$hash = 's/' . $seed . '/' . sha1_hex($prehash) . '/n';
 
 
$ua = LWP::UserAgent->new;
$res = $ua->post('https://sandbox.usaepay.com/gate.php', [
    'UMkey' => $sourcekey,
    'UMhash' => $hash,
    'UMname' => "Example Tester",
    'UMcard' => "4444555566667779",
    'UMexpir' => "0113",
    'UMcvv2' => "999",
    'UMamount' => $amount,
    'UMinvoice' => $invoice,
    'UMstreet' => "1234 Main Street",
    'UMzip' => "12345",
    'UMcommand' => $command
]);
 
 
print "\n\nresult: ".$res->content;
print "\n";
