Effective October 12, 2020 we are making the IP address input optional for all minFraud Score, Insights, and Factors queries. If you use these minFraud services for transactions where the IP address is not relevant (e.g. a phone order placed through a call center), you no longer need to include an IP address with your request. Note that the more data you send (including IP addresses, when applicable), the better the scoring the minFraud service will provide. See the relevant FAQ on our Support Center for more information.
