How do I block and unblock cards involved in fraudulent chargebacks?

Cards used for fraudulent chargebacks on the Adyen platform are automatically blocked for future purchases. Therefore, you do not need to take any action to block the card.

However, if you wish to accept payments with a blocked card, you can opt to put the card on your own accepted list.

Two ways to add a card to your accepted list: 

Through fraud settings

1. In the Customer Area, switch to your merchant account.
2. Go to Risk > Risk profiles > Card/Bank Account number referral > config. Your user account must be configured with the necessary user roles to make fraud setting changes.

Via the Payment page

1. In the Customer Area, switch to your merchant account.
2. Go to Transactions > Payments > PSP number of the blocked transaction > Fraud Control.

In both cases, the shopper must perform the transaction again to be accepted.
