Well I want to know , for test transaction , transaction id returned by authorized.net is 0 or different
Thanks in advance
You cannot run testmode for test transaction!
Ok, here's the deal. You can't run cards in test mode because you don't have an authorize.net test account. You can run your backend on authorize.net in testmode, but not your website in testmode. Leave your authorize.net in testmode and your website in regular mode.
That's why it won't work. Or just run it in regular mode all around and charge a penny on a product. That's another work around.
