Lists

Create your own lists of information to block, allow, or review matching payments.

You can create lists of specific types of information and use them in rules. For example, you might want to create rules using a list of:

• Blocked List. Use this list to automatically deny payments by these customers.
• Maximum Withdrawal Amount. Use this list to set the maximum withdrawal amount you can make.

Here's how you can add a list

Click the Lists tab in the toolbar, then click the Add Lists button on the far right.

Name This is a required field where you will provide a unique identifier for the list item. This name should be descriptive and help you easily recognize the purpose of the list.

Slug This is an optional field that allows you to specify a URL friendly version of the name. It is often used for creating permalinks or for SEO purposes.

Type This field determines the type of data that will be included in the list. You have the following options to choose from: Phone Number, Account Number, IP Address, Amount, Email Address, Card Number, Customer ID, Device ID, Location, or Name. Select the appropriate type based on the nature of the data you will be storing in the list.

Lists This is where you will input the actual list items. You can either enter the list items as a comma-separated list or provide them in a CSV file format. Ensure that the list items are formatted correctly according to the selected data type e.g., phone numbers in the correct format, email addresses with the proper syntax, etc.

After you've filled out all the needed fields you can now click the Add button. You'll get a toast telling you that you've successfully added a list.

Rules

Radar prevention rules allow you to take action whenever a payment matches certain criteria.

Chapas Radar provides built-in rules to help detect and guard against fraud risk for all users:

• Authorization Rules Criteria to determine whether a payment should proceed after a review.
• Block Rules Conditions to block payments based on specific criteria.
