crehbichler-SetupIntent

Hi there. the behavior is expected, as the first invoice is 0$ and eventhough there is an invoice.payment_succeeded, the payment_intent can be null. What you are doing is correct, you just need to check the content of payment_intent when received invoice.payment_suceeded to continue doing your logic

So I wouldn't set the default payment method for the customer in the invoice.payment_succeeded webhook event? Is there another webhook event for that?

[eager tiger]

When you use confirmCardSetup and customer entered his card information, you should receive the setup_intent.succeeded event

Okay. How do I know if this was the setupIntent from creating the subscription, and not one that was added later on?
So I know I can set the payment method of the setupIntent to default for the customer

Another idea would be to not rely on the webhook, but to attach + set the default payment method immediately after creating the subscription (in backend) for 0 amount payments

The distinguish the SetupIntent you would need to rely on its Id, like saving pending_setup_intent somewhere when you create such a Subscription. I would recommend to rely on webhook, as at the time the Subscription is just created, you don't know if the customer can actually authorize it or not

Makes sense, thank you!
