I am receiving "The merchant API Login ID is invalid or the account is inactive." when posting a credit card transaction from my website to my sandbox account.
The website has been integrated with authorize.net for credit card transactions for at least 4 years, and I am also adding ability to accept eCheck transactions as well. I created a sandbox account to test eCheck transactions and everything is working correctly. When I try to then send a credit card transaction with our existing code to the same account is when I recieve the error.
These are the fields we are currently sending for credit card:
x_Login is the API Login ID
x_Password is the Tranaction Key
The credit card integration code is currently being used to post to dozens of live merchant accounts, but doesn't seem to work for my sandbox account. I want to be sure that we can send credit card and eCheck to the same merchant account.
If anyone can shed some light on this for me it would be much appreciated. Thanks.
