Manage Referral Lists

Block and trust rules, also known as Referral rules, are straightforward and allow you to block or trust specific shopper attributes.

For example:

Email address
IP address
Phone number
Etc.

Usually the best practice is to either block or trust a certain data attribute. In case of blocked entries a minimum score of 100 or higher is configured. For trust listed entries a negative scoring of -100 or lower is common.

In case you would like to partially score - for example on a certain issuer country/region or email domain, the best practice is to build this in a specific custom risk rule.
