MANAGING TRANSACTION BLOCKING SCHEMES BASED ON PERFORMANCE DATA VIA A USER INTERFACE

The disclosure herein describes management of transaction blocking schemes via a user interface. A transaction blocking scheme is receiving via the user interface from a user, including transaction blocking rules. The transaction blocking rules are applied to transaction data associated with the user. Transaction blocking scheme performance data is generated based on the application of the transaction blocking rules to the transaction data, including a quantity of transactions of the transaction data that are blocked by the transaction blocking rules. A visualization of the transaction blocking scheme performance data is displayed via the user interface and the user is prompted to provide a response based on the displayed visualization. Based on the response to the prompt, the transaction blocking scheme is activated for application to incoming transactions, whereby the transaction blocking rules are applied to incoming transactions to determine whether to block the incoming transactions.
