hello, so Subscription already do create PaymentIntents under the hood

I am trying to make an on-session purchase of a subscription and subsequently the next payments will be off session.

that is by default how Subscription already work

so which guide are you following? most Stripe guides should already account for what you're trying to do, since that is how Subscription work

Currently I am collecting the payment methode using SetupIntent on the frontend, creating the subscription and assigning the payment methode to it on the backend with default status incomplete then confirming the automatically generated PaymentIntent. The problem is this makes the initial payment off session

This is relevant to me bc the user will have to go through authentication when adding their payment methode with SetupIntent, and again when the PaymentIntent is to be confirmed on the backend

var options = new PaymentIntentConfirmOptions{PaymentMethod = paymentMethod,};
var service = new PaymentIntentService();
service.Confirm(subscription.LatestInvoice.PaymentIntent.Id,options);

yeah so that is not the right way to integrate Subscription

which is why I asked what guide you are following

cause all our standard Subscription guides do not make you do this

like this one: https://stripe.com/docs/billing/subscriptions/build-subscription?ui=elements

it takes a payment up front

it does not do SetupIntents

(except for trials which is expected)

I honestly can't find the guide I used, but if this is not the right way to integrate it I will use the guide you provided me

[frozen epoch]

does this also save the payment methode after the purchase?

[royal magnet]

yes it does

Just went through the guide, looks like exactly what I need. I have a quick question regarding 3D Secure. When an off session payment requires authentication, how can I find the stripe page to show to the user? would be included in the invoice?

You could just point out the right place for me to look in the docs if it's already explained, I just can't find it

[royal magnet]

how can I find the stripe page to show to the user? would be included in the invoice?

two options there

1/ redirect the customer to the Hosted Invoice Page, which gives them an out of the box "card Element" field supporting 3DS https://stripe.com/docs/api/invoices/object?lang=node#invoice_object-hosted_invoice_url

2/ redirect customer to your payment page where you mount Card/PaymentElement yourself and pay the Subscription's Invoice's PaymentIntent

[frozen epoch]

for 1/ will they have to resubmit their payment methode?

or will the autherization window pop up directly?

for 2/ does that mean sharing the Intent Id with the frontend and attempting to confirm it while the user is on session?

[royal magnet]

1/ either pay with existing card or add a new card (try it out in test mode)

2/ yes

in both cases, you are bringing your user "on session" really

cause you have to bring the customer to some page, whether your own or the hosted Invoice Page
