Hey! Yep, you can list PMs saved on a specific Customer object: https://stripe.com/docs/api/payment_methods/customer_list
velvet grove
OK, that will return all the payment methods. I can pass the following parameters ending_before, limit, starting_after can I filter by fingerprint
mighty stump
No, you can't. What are you specifically trying to do
velvet grove
I am trying to integrate Stripe with our gateway. We have a connect setup. Us -> Accounts -> Customers
We process payments using Stripe but through our API. We have a payment page, Customers can pay to an Account. I have setup a payment page with a CardElement that posts PaymentIntentID, Token & User Data to our end point.
I have managed to process the data, and send the payment to the correct Account storing the customer & payment so that it appears in the correct Account
I check the Account customer by Email to avoid duplicates, but if I use the same card, I get 2 instances of the same card in the Stripe Account
mighty stump
Yep, you can have multiple Payment Method objects which are from the same underlying credit card
velvet grove
OK, so every time they pay with that card they and new Payment Method is created?
Is there no way of checking and using the Payment Method that already exists?
mighty stump
Well, there is. But you'd need to implement the logic for that. The fingerprint field is generally unique
What most people do is build a UI that lists the saved PMs to present to their customers to select from
Can show the last 4 digits, brand, etc
velvet grove
We would like to do that, but in this scenario the Customer add their details before we know who they are.

That will be an option which is why we would prefer one PaymentMethod per card
mighty stump
Then you will need to check the fingerprint field of existing PMs on the Customer
velvet grove
So I would need to get Customer's PaymentMethods iterate through them, compare fingerprint with one supplied and if it exists use the exists card_id
mighty stump
Yep, that's the recommended approach!
velvet grove
OK thanks
mighty stump
Sure, np!
velvet grove
Enjoy the rest of your day
mighty stump
you 2!
velvet grove
Sorry one more question
mighty stump
Sure!
velvet grove
in my current flow I create a source using the token supplied
can i use a PaymentMethod is it exists?
mighty stump
You should most definitely use Payment Methods and not Sources
Sources are an older, deprecated API
velvet grove
OK
