hi! do you have some examples like a customer ID cus_xxx and some screenshots of what you're describing?

[shy smelt]

This customer pays with the same link email and it just keeps adding to their payment methods

cus_QKNkMYych5JHeq

this is a dev customer

[brisk tinsel]

I see

I don't know much about Link-as-PaymentMethod. Not sure how you'd handle this, usually there's a fingerprint on card paymentmethods so you can detect duplicates and remove them yourself but seems like that's not the case for Link.

Hey! Taking over for my colleague. During your tests, are you using the same email or different email when using Link ?

[shy smelt]

the same email

the only way i can pay with link without this happening is if i create a payment intent and confirm the payment automatically but then i don't know if this is the right way for link because it doesnt give the user the option to login with link etc it just triggers the payment

[worthy yarrow]

The customer have two payment methods: pm_1PU3h2DLwtSLU8I5b6vAtABO and pm_1PToKKDLwtSLU8I5tE8Ot26z which referes to the same card 4242

Ok let me check further...

[shy smelt]

yes this is as expected because i added a new card but with the same number

but i was not expecting this with link because the user logs in and goes through verification then pays and this adds the new link payment method

[worthy yarrow]

Same happens with Link, when you are adding a new Payment Method ?

[shy smelt]

yes

i can trigger the payment without the link verification and it does not create a new payment method, but then it functions link a card payment.
will this sometimes open a iframe for verification etc like it does with card?

i will take some screen shots

this is a logged in link user, showing their saved payment methods

i was expecting not to create a new payment method because they are logged in even through this flow that creates a new payment method. does that make sense?

[worthy yarrow]

Could you please provide some additional code snippets, on the frontend part ?

[shy smelt]

i am using the PaymentElement in next js to show this

i only show this if the user needs to add a new payment method otherwise i just automatically trigger payment using the backend. is this correct for link?

[worthy yarrow]

Can you share the code behind this screenshot ?

[worthy yarrow]

OK I see, so you are using PaymentElement in order to collect a new PaymentMethod whether it's a Link or Card or others...

[shy smelt]

correct

[worthy yarrow]

But I'm not sure what is the difference between Link and Card... you can keep adding the same PaymentMethod using the same card number or Link using PaymentElement

a new PaymentMethod Id will be gnereated

if you want to keep only one PaymentMethod corresponding to a card or an email, then manually you need to check the fingerprint of the card and see if there is pervisouly registred card.

[shy smelt]

i guess my main question is does stripe.handleNextAction handle link, for example if the user needs to login etc?

because i know for card it shows an authentication window

this way i don't need to go to the PaymentElement and login which then also creates a new id

i use this to trigger payments to existing payment methods, does this work for link?

[worthy yarrow]

Yes it should handle any required next_action for the PayemtnIntent, so I assume it works for. Links too.

[shy smelt]

ok i think that will be fine then. thanks for the help
