Yes the sample code works for me locally on my PC with the WAMP setup.

So for now the new API isn't returning the same yet, I should be able to
figure it out.

Thanks again

We have just started using the Payeezy system Jack and found that the PHP
sample code they supplied works perfectly to create the hash.

This is our modified version of that code:

// String together the values that contribute to x_fp_hash
$hmac_data = $x_login . "^" . $x_fp_sequence . "^" . $x_fp_timestamp
. "^" . $x_amount . "^" . $x_currency_code;

// Form the MD5 hash using the transaction key
$x_fp_hash = hash_hmac('MD5', $hmac_data, $transaction_key);


Since that part of our system is PHP based I have not had a need to
perform the same task from RPG so I can’t help you there.

I knew my post was long but I thought I put it together properly. The
website name is payeezy.com. Not sure if it's worth posting since you

need

a user id/password to use their testing tools.

In my first post i stated that I was using the Qc3CalculateHash and the

the

sample code was using the PHP HMAC-MD5, I didn't know that Hmac and MD5
were different.

Thanks for clearing that up. I'll look at the other API

HMAC is not just an MD5 hash. Go to
http://www.freeformatter.com/hmac-generator.html to see a web site

that

will match up with the example you are given.

Yes, finally. If he'd just come out and said HMAC from the beginning,
it would have saved a lot of trouble.

And yes, I've confirmed with Python also that the example he's looking
for is an HMAC using the MD5 algorithm, with the "salt" as the key.
