Login to the Authorize.net payment gateway here: https://account.authorize.net/
Check that gateway is NOT in test mode
If your gateway is new, and you have not used it before, it may be in "test mode:, it needs to be in "live mode". To check, please click on the "Settings" menu item and then click on the "Test Mode" menu item.
There you will find the button that will toggle the mode between "test mode" and "live mode", make sure it's in "live mode".
API Login ID and Transaction Key Location
While on the settings page, make sure you know where the link for "API Credentials & Keys" is located. You will see it near the link for "Test Mode".
You will need to cut and paste the API Login ID and Transaction Key into the Payment Gateway setup area within the Lodgix.com application. For now, just know where it is located within the auth.net payment gateway.
Enable Customer Information Manager (CIM)
And finally, you will need to enable the Customer Information Manager (CIM) within authorize.net. This is required if you wish to use Authorize.net with Lodgix.com. CIM allows you to securely store your guest's credit card number at the authorize.net servers.
To enable CIM, return to the main menu for authorize.net and click on the "Customer Information Manager" menu item (see screenshot below) and then follow the steps to enable it within your account:
Connect Authorize.net to Lodgix
Within Lodgix, navigate to Settings > Payment Gateway Setup
Select Autorize.net from the list of Payment Gateways
Enter your API Login ID and Transaction Key (from Authorize.net)
Optionally, enable authorization holds
Confirm that you have enabled the Customer Information Manager within Authorize.net
Accepted Payment Types
Once connected to Authorize.net, click on the "Accepted Payment Types" tab and choose which cards you want to accept.
Test the Setup of the Payment Gateway
