The Authorized API IP Addresses tool allows you to specify the server Internet Protocol (IP) addresses that are exclusively authorized to submit transactions for your payment gateway account using the Authorize.Net API. Transactions received from any IP address NOT included on your Authorized API IP Addresses list will be rejected. Only IPv4 addresses are supported at this time.
IMPORTANT: This tool is only applicable for Authorize.Net API transactions. Do not use if you submit transactions using a payment method hosted by Authorize.Net, for example, SIM.
The filter status, Filter Enabled, Filter Disabled or Not Configured appears at the top of the page.
To enable the Authorized API IP Addresses Tool:
Step 1: Click the Enable Filter check box at the top of the page. Or, to disable the Authorized IP Addresses Tool, make sure that the Enable Filter check box is deselected.
Note: If you choose to disable this filter, the IP addresses previously entered will still be saved, but will have effect.
Step 2: To add an IP address to the IP Address List, enter the first set of digits of the IP address in the first text field, the next set of digits in the second text field and so on and click Add››. You can have up to 500 IP addresses in your API IP Address List. This tool does not support IP address ranges.
Note: You must list at least one IP address in order to enable this tool.
Step 3: To remove an IP address from the list, click on the IP address you would like to remove on the right side of the page and click ‹‹Remove.
The Total IP Address Count indicates the number of IP addresses currently included in the API IP Address List.
Step 4: Click Save to save your settings or click Cancel to cancel the action.
Your saved settings are applied immediately to all transactions screened by the Advanced Fraud Detection Suite.
Transactions that are rejected by the Authorized API IP Address tool are blocked entirely by the payment gateway. They are not tracked nor are they available for review.
