hello, reading up one sec

well so you have a unique scenario (limit of 1 sub per customer) so there is no tutorial for this

but really what you can do is:

Is there a way to somehow cancel subscription and PaymentIntent confirmation from step 1), before starting subscription flow 2)?

you can a/ reuse the PaymentIntent and sub from the first try, those still exist and can be reuused
or b/ you can cancel the first Subscription and create a new one

you can do this via https://stripe.com/docs/api/subscriptions/list#list_subscriptions-customer
so list all subs on that Customer and if >0 then either reuse the existing PaymentIntent to re-call confirmCardPayment() or just cancel that and create a new one

How much time (X from step 2) should be allowed to pass between starting subscription 1 and initiating another "create subscription" flow for the same customer?

timing doesn't matter here

Thank you for the quick response. The answer makes sense but this recommendation is still prone to race conditions:

b/ you can cancel the first Subscription and create a new one

Since the customer has 3DS modal open for subscription 1, they could be confirming a subscription at any moment. This could happen:

• I check subscription 1 via API - it has "inactive" status
• The customer confirms PaymentIntent for subscription 1, subscription is "active", charge is made
• I cancel subscription 1 because I think it's inactive.

Does stripe have an API mechanism to somehow enforce "atomic" actions? Or something else that would help with the above scenario?
Thanks a lot!

Hi @hallow jacinth not sure if I'm eligible for another sub-question above, but I just want to make sure you see it. Thanks
