Hi 👋 it's not in the payment form, but Payment Methods that can be identified for duplication will contain a fingerprint field that can be referenced to build your deduplication logic. For instance, card Payment Methods have a card.fingerprint field that will uniquely identify a single card, so you can delete extra Payment Methods if their fingerprint matches one you already have for the customer.

I see it, so that field its only generated when payment method is added right? is that something that I can get from response?

[empty wave]

Yes, that's provided when the Payment Method is created, or can be found within a Confirmation Token if you're using those. When you ask if this is something you can get from the response, what response are you referring to there?

[bleak jasper]

I was referring to the response that returns when successfully creating a payment method, but the information you have given me is enough, thank you very much!
