Hi
How are you preventing card testing? what did you implemented so far?
Check this list:
https://stripe.com/docs/disputes/prevention/card-testing#prevent-card-testing

#

i have added captch, limited the number of payments from one ip address, request coming only from our host is handled

#

yet still some payments are coming

#

with differnt ip's

uncut fox Jul 21, 2023, 11:21 AM

#

What makes you saying that those payments are test payments ?

#

can you share a sample ?

elfin pilot Jul 21, 2023, 11:22 AM

#

sure just a minute

uncut fox Jul 21, 2023, 11:23 AM

#

because if the user want throw captcha and submit a payment that means not a Card testing, but a normal payment attempt or your secret key is leaked and you need to roll it

Thanks for sharing, the PaymentIntent pi_3NW5QdBaSTFI9lAz1sCvQkrE was confirmed from your frontend (req_1iChk3YqZQNjmd) if your frontend has captcha then it's not considered as a test payment... because the user went throw normal process I would say

#

If you want, you can improuve that by using radar and allow minimal number of failure payment by IP

elfin pilot Jul 21, 2023, 11:32 AM

#

we have already enabled radar

#

but we know this is a wrong payment and if disputed

#

we will be charged

#

elfin pilot but we know this is a wrong payment and if disputed

A failure payment can't be disputed. Only successfull one

elfin pilot Jul 21, 2023, 11:33 AM

#

this one is successfull

#

The merchant did the payment from your frontend using a valid card

elfin pilot Jul 21, 2023, 11:41 AM

#

there are multipe payments from same ip address

#

different cards

uncut fox Jul 21, 2023, 11:42 AM

#

You can set a radar Rule in order to block that I think

elfin pilot Jul 21, 2023, 11:43 AM

#

can i share a email from stripe

uncut fox Jul 21, 2023, 11:43 AM

#

What kind of email ?

elfin pilot Jul 21, 2023, 11:44 AM

#

I think you should reach out to Stripe Support and narrow this further, check what kind of other Radar rules you can implement in your integration to prevent more cases:
