Hello, I'm trying to setup something to verify that credit card numbers are not returned (phase 4 I believe). Easily enough I can setup a regex to verify - but that could lead to false positives. I know that you can execute an external script when you get a match, but can you then get the results of that external script? I'd just like to run a Luhn check on the number, if it comes back positive then I'll react, otherwise I'll let it through. Any help is appreciated. Thanks, Matt |
