Hi 👋 is this something you're trying to implement using Radar Rules, or are you writing your own code to do the detection?

using radar rules

Gotcha, we aren't too familiar with writing Radar Rules in this forum, but yeah, I'm not seeing anything mentioned that looks like it would allow you to provide a string to compare to the name of the issuer.

Each issuer will have their own set of BINs (first six numbers in a card number) though, so you might be able to build around the BINs that belong to the issuer you're worried about:
https://stripe.com/docs/radar/rules/supported-attributes#card-info

I'm not sure how to get that list of BINs though.

ok - can I get the information through a webhook, so I can write a code to detect by myself ?

the card issuer information I mean

[tawny yew]

Let me double check that.

No, it does not look like that information is available in the API by default. I would recommend reaching out to our Support team with an explanation of your use case, explaining what types of payments you're trying to block and why, to see if there is anything they can do to provide you with that information.

If not then blocking by BINs via a Radar Rule may be the best approach. I believe our colleagues in Support are also more familiar with Radar Rules than we are in this forum, so it may be worth checking with them to see if they know of a better approach as well.

Thank you, i'm quite surprise we can't have this information throught the API

The difficulty with the BIN is to identify this number for each bank : In Stripe, the BIN information is not displayed, which does not help

Any time, sorry I couldn't be of more help this time. I would strongly recommend following up with our Support team though.
