What is the recommended way to handle SCA for customers subscribing to a plan with an upfront fee?
This is the recommended Subscription integration:
https://stripe.com/docs/billing/subscriptions/build-subscriptions?ui=elements
You should use default_incomplete

Also, is this confirmation of payment intent considered as off session or on session? Should I create the subscription as on session?
The payment attempt of the first invoice is done on_session as the customer is in the checkout flow.

I see, and so once this is set up does this guarantee further recurring charges wont have 3d secure

or is there no guarantee of that

if not i guess i can use Stripes built in 3d secure email?

[west saddle]

Yes, the bank issuer may sometimes requires a 3ds auth

[west saddle]

yes, you can configure this in your dashboard settings:
https://dashboard.stripe.com/settings/billing/automatic

Whats the difference between allow incomplete and default incomplete though

[west saddle]

Use allow_incomplete to create subscriptions with status=incomplete if the first invoice cannot be paid
and
Use default_incomplete to create Subscriptions with status=incomplete when the first invoice requires payment, otherwise start as active

[stoic vessel]

so i take it this means in scenarios where the subscription can get created successfully it would start off as incomplete?

for default incomplete i mean

as in if i have a payment method on file and i create subscription it can either

1. fail (maybe due to 3d secure requirement)
   or
2. succeed

[west saddle]

1. fail (maybe due to 3d secure requirement)
   When following the guide I shared with you, it shouldn't fail, because that integration take into account 3ds too

[stoic vessel]

to differentiate between 1 and 2, in the backend should i have some condition to check like this

// ...
}```

cuz if it fails to update i will have to send the client secret back like subscription.LatestInvoice.PaymentIntent.ClientSecret

[west saddle]

What update are you trying to do ? you should just follow the guide I shared with you, you don't need this check particularly when creating a Subscription.

Hmm yes ur right, it seems that i get back a payment intent regardless of whether or not the customer has a valid card on file or not which is what im looking for
