No you would not pass a payment_method to confirmPayment via Stripe.JS. Can you tell me more about what you are trying to do?

#

And you can't have a PaymentMethod without knowing its type 😅

craggy rampart Mar 2, 2023, 2:11 PM

#

we store payment methods for existing customers in our system

#

when you update a subscription in our system you can choose an existing payment method

#

additionally, this is the same page to resolve unpaid subscriptions

#

so we may have a payment intent already

#

I really hope you guys add support for existing payment methods on customers soon to Payment Elements

sullen zinc Mar 2, 2023, 2:13 PM

#

Yeah we are working on adding that

#

For now, you would just create/confirm a PaymentIntent server-side

#

You don't use Stripe.JS for this at all

craggy rampart Mar 2, 2023, 2:14 PM

#

until the payment intent needs customer action

sullen zinc Mar 2, 2023, 2:15 PM

#

Right, then you would pass the client_secret to the frontend and use confirmCardPayment or whatever method is correct for the type of PaymentMethod you are confirming that requires action

#

what about the situation where i have a subscription that is unpaid

#

i tried updating the subs default_payment_method

#

but then I just get an error when trying to confirm the payment intent that it has no source

#

do you have to manually update subs payment intent?

sullen zinc Mar 2, 2023, 2:17 PM

#

You do the exact same thing that I stated above for an unpaid Sub

#

You would only have to update it if you are going to use a payment_method_type not already set on the PaymentIntent

#

Ah actually no

#

You just pass payment_method_types when you confirm

#

You don't have to update at all

Maybe I'm not explaining myself properly

#

I have a subscription that is currently unpaid

#

Lets say the card is expired

#

I want to update it with a new payment method

#

I already have that payment method on the customer.

#

What is the proper flow for that

#

I would've assumed I update default_payment_method on the subscription

sullen zinc Mar 2, 2023, 2:20 PM

#

default_payment_method will be used for future automatic confirmations

#

If you have an open invoice that is out of retries then you need to manually confirm its PaymentIntent yourself

#

Using that new PaymentMethod you want to attempt to charge

craggy rampart Mar 2, 2023, 2:21 PM

#

ok, so in my two separate scenarios, what would my flow be?

We have the user's card in Stripe already
They want to add a new card

sullen zinc Mar 2, 2023, 2:26 PM

#

1/ You confirm the PaymentIntent server-side with the PaymentMethod you want to charge
2/ You present Payment Element and use confirmPayment client-side using the PaymentIntent's client_secret that you want to charge

craggy rampart Mar 2, 2023, 2:27 PM

#

It sounds so simple when you lay it out that way

#

until I try and integrate it all into one page

#

lol

sullen zinc Mar 2, 2023, 2:29 PM

#

lol

craggy rampart Mar 2, 2023, 2:29 PM

#

i forgot one more scenario. this page lets me update the subscription when it's in a good state. in that scenario if the customer adds a new card what am I suppose to do? I currently was creating a setup intent for that

sullen zinc Mar 2, 2023, 2:29 PM

#

I definitely understand the desire to handle this all through Payment Element

#

We are working on that!

#

Yep SetupIntent is correct if you are adding a new PaymentMethod but not charging it immediately

craggy rampart Mar 2, 2023, 2:30 PM

#

basically building an "edit subscription page" that lets you handle, change plan, update bad payment method, add new one, etc is a nightmare

#

lol

sullen zinc Mar 2, 2023, 2:30 PM

#

Yep I know there are a lot of flows you have to account for

craggy rampart Mar 2, 2023, 2:31 PM

#

ok i think I have some ideas. i'll get back to banging my head against my keyboard trying to hash all the scenarios out

#

oh wait, one other unrelated question

#

you know how setup intents have payment_method_details with a nested generated_sepa_debit for things like iDEAL or Sofort

#

are there any other payment methods that do this sort of thing

#

for something besides generated_sepa_debit

sullen zinc Mar 2, 2023, 2:32 PM

#

Yep they should, and no only those bank redirects that create SEPA Debit

#

Hmm actually let me double check

craggy rampart Mar 2, 2023, 2:33 PM

#

just confirming, there is no other payment methods that I have to dig into the latest attempt to find the actual payment method

sullen zinc Mar 2, 2023, 2:34 PM

#

Yeah just Bancontact, iDEAL, Sofort
