In addition to Allow, Block, and Review, you can write a Radar rule to perform what action?

• A. Request 3DS authentication
• B. Refund the payment automatically
• C. Change the currency of the charge
• D. Delay the payment processing by 5 minutes

Answer: (A)

Radar rules extend how you handle a payment beyond simply allowing or blocking. They can require the cardholder to complete 3D Secure authentication, adding an extra verification step for high-risk cases or to meet Strong Customer Authentication requirements. This is the best option because 3D Secure is an approved action you can trigger to verify the payer directly with their bank, helping protect you from fraud while keeping legitimate customers moving through with an extra layer of security. The other options aren’t actions Radar rules perform—refunds automatically, changing the currency, or delaying processing are separate operations that aren’t part of Radar’s decisioning flow.
