How can I help a payment service user detect fraudulent or malicious use of their account when providing Open Banking services?

Payment Service Providers (<a href="/glossarycollection/payment-service-provider" style="color:#48277C;" target="_blank" title="Payment Service Provider"><u>PSP</u></a>) should provide Payment Service Users (<a href="/glossarycollection/payment-service-user" style="color:#48277C;" target="_blank" title="Payment Service User"><u>PSU</u></a>) with the option to receive alerts on initiated and/or failed attempts to initiate payment transactions.
