Hello everyone. I am not credit card processor, gateway integration literate by no means. I was just handed this daunting task when we changed credit card processors. I am find myself without a gateway because of the MD5 change and needing the signature key. I'm using ECWID for my online shopping cart. I have no idea how to make a signature key and auth.net's instructions are not made for a person like me. Again, have no idea what to do.
