You can call this API to retrieve the list of payment methods that are already saved to a customer https://docs.stripe.com/api/payment_methods/customer_list, and compare the newly collected payment method's fingerprint (https://docs.stripe.com/api/payment_methods/object?lang=cli#payment_method_object-card-fingerprint) against existing ones

In order to get the fingerprint, fitst i have to create the payment method and then need to check with the existing ones right

[rain vine]

type: "card",
card: cardElement as StripeCardElement,
billing_details: {

address: {
line1: addressLine || null,
country: country || null,
state: state || null,
city: city || null
}
}
});
