So I can't do that without the extra paid radar option?

You could alternatively track on your end and perform a check against the email for each transaction before payment occurs

#

But Radar is the Stripe option for this scenario

#

There are a bunch of other mitigations that you can take to stop card-testing, so you might see if these solve your problem: https://stripe.com/docs/disputes/prevention/card-testing#prevent-card-testing

#

Most of those are oriented toward programmatic card-testing though, so if you're seeing manual card testing, then Radar is going to be your best bet

Righto, we're using payment links and have seen a few attempts of this recently. Stripe blocks them but then let's them try later.

Ah, very odd. We don't often see manual testing like that
