I have configured the authorize.net in my new magento 2.0.5. I have updated my sandbox api login id, transaction key, merchant md5, and changed the url into https://test.authorize.net/gateway/transact.dll for testing.
Also i have enabled the test mode and debug mode to track. While placing the order I'm receiving the error on alert box Please enter a transaction ID to authorize this payment.. While checking /var/log/debug.log transaction id (x_trans_id) was in 0. I suspect that the issue is with the transaction id.
