How to blacklist a transaction
If you are suspicious of a transaction and would like to prevent that person from conducting further transactions, you can blacklist the specific details of that transaction so that it cannot happen again. More specifically, you can blacklist the person’s country, email, credit card number, and/or his or her IP address.

Let’s say that a transaction has appeared with a strange error code. Click the View 🔍 button on the transactions list to open it.
In this example, the code is reporting a stolen card. Shopper information is noted as well
To blacklist any of this shopper’s data:
Go to the Blacklist tab.
Click the Add an entity :plus: button.
In the window that appears, tick the properties of that transaction that you would like to blacklist:
We are interested in blacklisting the person’s shopping details, not his or her country
Click the Add button. If this email, IP address or credit card number is detected in a future transaction, we will not let it go through. It will show up in the system with status “declined”:
A declined transaction due to a blacklisted credit card
The return code will correspond to the element you have blacklisted: 500 - Card is blocked; 501 - Customer E-mail is blocked; 502 - Customer IP is blocked:
Result code 500 for a declined credit card transaction
Note that transaction details are blacklisted per Originator. (These details will not be blacklisted for any other of your Originators, if you have more than one.)
It is not possible to blacklist a customer’s IP address if it is not known. Furthermore, blacklisting a public IP address will cause false positives. We therefore recommend only blocking that customer’s credit card number and email.
