You are right, sorry I missed the HMAC part. It was this:

Here is their sample code

HMAC-MD5(transaction-key, "x_login^x_fp_sequence^x_fp_

I don't believe HMAC-MD5 is an actual (built-in) function in PHP or
any other programming language, though. It's more of a math or
computer science term that refers to one method of generating a secure
hash. You even later said the real PHP function was hash_hmac.

Still, it's on me that I didn't notice that in your original post.
