Setting up Authorize.net

[jcb22]

I am trying to setup Authorize.net as my payment gateway. I am already stuck on the third question... MD5 Hash - What is it and how do I set it up?

I logged into my account at Authorize.net and I don't get much help there. All it says is to set it... How do I set it. I noticed that current the setting is set to "no"

Do I set it to "yes"

The zen car says :
MD5 Hash
Encryption key used for validating received transaction data (MAX 20 CHARACTERS)

*Set A Hash Value at AuthNet Admin*

Do I just type in up to 20 random characters

Easy ... You can put in a word, a phrase, random characters ... whatever you like. Up to 20 characters.
