I am trying to set up my authorize.net account to process credit cards online. I entered my login credentials in the Nexternal system, and processed a transaction. I received the following error, "This account has not been given the permissions required for this request." What is wrong?
Most likely, you have entered your login credentials to access the authorize.net website, or other personal login credentials, rather than your actual API login ID and Transaction key. You need those two specific values to activate the integration.
