Assign a variable type to a list

Every list you use in a rule must be associated with an Amazon Fraud Detector's Variable types variable type. By default, Amazon Fraud Detector assumes the list to be of FREE_FORM_TEXT variable type. It is important to note that a list that consists of IP addresses must be associated with IP_ADDRESS variable type.

You can associate your list with a variable type either at the time of list creation or anytime later. If you already associated your list with a variable type and want to change it later, you must create a new list. You can’t change the variable type of a list.

You can assign a variable type in the Amazon Fraud Detector console, using the API, using the AWS CLI, or using the AWS SDK.
