The "authenticator" is created by generating an MD5 checksum (in
hexadecimal) on a string created by concatenating the following fields (in
the order specified):
1.A secret merchant identifier that will be issued by First American Payment
Systems to each FirstPay.Net merchant.
2.The merchant field above.
3.The ticket field above.
4.The amount field above.
any help would be appreciated.
$secret_merchant_id = blah;
$merchant = foo;
$ticket = bar;
$amount = baz;
echo md5($secret_merchant_id.$merchant.$ticket.$amount);
