You can create a list containing input data (entries) of a variable in your event dataset and use the list in rule expression. The entries in the list can be managed dynamically without updating the rule that is using the list.
To create a list, you must first specify a name and then optionally associate the list with a Variable types supported by Amazon Fraud Detector. By default, Amazon Fraud Detector assumes the list to be of FREE_FORM_TEXT variable type.
You can create a list in the Amazon Fraud Detector console, using the API, using the AWS CLI, or using the AWS SDK.
Create list using the Amazon Fraud Detector console
To create a list
-
Open the AWS Management Console
and sign in to your account. Navigate to Amazon Fraud Detector. -
In the left navigation pane, choose Lists.
-
Under Lists details
-
In the List name, enter a name for your list.
-
In the Description, optionally, enter a description.
-
(Optional) In the Variable type, select a variable type for your list.
Important
If your list contains IP addresses, make sure to select IP_ADDRESS as the variable type. If you don’t select a variable type, Amazon Fraud Detector assumes the list to be of FREE_FORM_TEXT variable type.
-
-
In the Add list data, add list entries, one entry in each line. You can also copy and paste entries from a spreadsheet.
Note
Make sure that the entries aren’t separated using a comma and are unique in the list. If two identical entries are entered, only one will be added.
-
Choose Create.
Create list using the AWS SDK for Python (Boto3)
You create a list by specifying a list name. You can optionally provide a description, associate a variable type, or add entries to your list when you are creating a list. Or, you can update the list later on by adding entries or a description. You can assign a variable type to the list later if you haven't assigned it when at the time of list creation. Variable type of a list cannot be changed after it is assigned.
Important
If your list contains IP addresses, make sure to assign IP_ADDRESS as the variable type. If you don’t assign a variable type, Amazon Fraud Detector assumes the list to be of FREE_FORM_TEXT variable type.
The following example uses CreateList API operation to create
an allow_email_ids list by providing a description, a variable type, and by adding four list entries.
import boto3
fraudDetector = boto3.client('frauddetector')
fraudDetector.create_list (
name = 'allow_email_ids',
description = 'legitimate email_ids'
variableType = 'EMAIL_ADDRESS',
elements = ['emailId _1', 'emailId_2', 'emailId_3','emailId_4']
)
