Paypal Payments Pro - Advanced Fraud Protection not working -


i need annoying problem. have paypal payments pro account , use paypal_merchant_sdk (.net) process direct payments on our site via api calls using live credentials got paypal.com. have been live several months, transactions processing successfully.

now want small change way accept payments. want reject transactions wrong cv2 code. after calls paypal support told needed advanced fraud protection added our manager account (manager.paypal.com). added , set "csc failure" fraud filter reject transactions on non-matches , deployed live (active mode). status messages deployed successfully. waited several hours , tested, didn't work - still processes transactions wrong cv2 code , message "this transaction approved. however, card security code provided had few, many, or invalid character types but, per account option settings, not required in approval process."

can tell me why csc failure setting not working , how working?

edit: ok, on phone paypal support again , have use manager.paypal.com login credentials part of each transaction in api calls. know that? see fields api credentials.
