1. Input (cut and paste) your production Merchant Account Credentials. 2. Select the PRODUCTION mode if you have real credentials and are ready to sell online. 3. Click the green "Save As Current" button. NOTE: Testing your account will be done with TEST CREDENTIALS provided by the GATEWAY you are using. Real account information CAN NOT be used for testing. As long as you paste your credentials in correctly, there is no need to test as these integrations work already.
