I recently had a bot attack my Stripe subscription form with fake cards, and had to set up a captcha to try and mitigate the problem. I later found out that new subscriptions were being dropped with the error message “Missing or invalid security verification. Please try again.” after carrying out the 3D security verification.
This turned out to be caused by the captcha and payments work fine again after disabling it, but quite honestly this should not be happening. Is there any way this can get fixed? I’d feel much safer having a captcha on that page after the attack I had to deal with.
