Authorize.net error 103
I am getting the error 103 that means invalid credentials. I have checked and double checked and have the correct api credentials in place. I have tested it on a different shopping cart (non Webassist) and it connects fine. I'm thinking it may be the md5hash as I do have a 'specific' hash set in the Authorize.net control panel. I cannot find where to put it in Webassist. I realize I may be barking up the wrong tree and it may have nothing to do with the md5hash. Thanks for your help.
