There is one option available to add to your allow list and two options for adding to your block list.
For the first option, navigate to Settings and select Fraud management from the sidebar menu.
Once you're in the Fraud management section, you can manually add to your allow and block list. Please note that this is the only option for adding to your allow list.
For a easier and quicker way to add to your block list, navigate to the Payments tab and select the transaction you'd like to review. Once you've opened the transaction you'd like to add to your block list, click the kebab menu in the upper right-hand corner and select "Add entity to block list."
This option is recommended as it automatically creates multiple entries with one click, and the values from the parameters will be picked from the transaction directly.
