Supported payment methods with Radar

Radar fraud protection is active by default for all Stripe users. Radar screens all payment methods against default risk controls, and blocks all high-risk transactions.

Default risk controls for all payments

Radar users on Standard or above are protected by a set of default risk controls that block high-risk payments. Radar is on by default, and applies to all payment methods. Radar supports most preview payment methods, but not deprecated payment methods.

You can view blocked payments on the Radar risk controls page in the Dashboard.

Custom risk settings

If your plan supports this feature, you can customize your risk settings for the following payment methods:

Risk controls

You can customize your risk controls with these features:

• Block and allow lists: Automatically block or allow transactions based on email address, IP address, email domain, and more.
• Custom rules: Create tailored fraud prevention logic using attributes.
• Rule backtesting: Test changes against historical data before implementing them.
• Radar analytics: View consolidated fraud and performance metrics across all of your payment volume.

Payment method rules

By default, all supported payment methods inherit your active Radar rules and settings. You can adjust individual payment method rules with the :payment_method_type: attribute.

For example, this rule applies only to transactions using Bacs Direct Debit, where the customer IP address has a high number of disputes:

Block if :payment_method_type: = 'bacs_debit' and :dispute_count_on_ip_weekly: > 3
