Hi there!

[wheat otter]

hi

[lapis flax]

I'm not sure I understand your question. Can you clarify?

[wheat otter]

I've made a subscription

with a credit card respecting the sca2 validation

it's okay for you?

[lapis flax]

What do you mean "it's okay for you"? What's your exact question?

[wheat otter]

I just asking if it's clear for you before I continue my explaination

I continue so

the subscription still working month after month

but the customer sees that is payment card is expiring, so he wants to add a new one to the subscription to avoid service cancelation

how do we change the card (paiement method)? Do we have to respect a new sca2 validation?

[lapis flax]

So you want to change the payment method used for an active subscription? Do you want to do that before or after that an invoice is created and failed?

[wheat otter]

before that an invoice is created

[lapis flax]

Got it. So you would need to create a SetupIntent to attach a new PaymentMethod to the customer, and then set it as the default payment method for that customer.

[wheat otter]

so

const setupIntent = await stripe.setupIntents.create({
payment_method_types: ['card'],
});

I get a client secret

I use stripeElement to validate the card with this client secret

now the customer has the new PM so i change the default paimentMethod on the subscription

that's it?

[lapis flax]

Yes, exactly! For the last step, you can either update the default payment method of the customer (https://stripe.com/docs/api/customers/update#update_customer-invoice_settings-default_payment_method) or the default payment method of the subscription (https://stripe.com/docs/api/subscriptions/update#update_subscription-default_payment_method)
