Hi, let me help you with this.
When you set the PaymentMethod on the Subscription it should already be set up by that time, i.e. 3DS has already been taken care of.
How are you getting the PaymentMethod right now?
dusky quartz
At that time 3DS taken care. In my system, customer add multiple card, I switch card using payment method id I already have.
but when card get switch it should ask 3DS again for already stored card.
https://docs.stripe.com/api/subscriptions/update#update_subscription-default_payment_method
I am following this api, the payment method get switch automatically when I call the api. But when it try to process invoice it gets failed.

but when card get switch it should ask 3DS again for already stored card.
Why?
dusky quartz
because generally when we create subscription on card, it generate mandates in the card after confirming 3DS.

Is this your own requirement to ask for 3DS before updating the card?

The point of using SetupIntents to collect PaymentMethods is to avoid needing to do 3DS in the future: https://docs.stripe.com/payments/save-and-reuse?platform=web&ui=elements
After the card is set up you can use it with Subscriptions and one-off payments freely, without repeating 3DS
dusky quartz
Let me explain you.
I have normal upfront package buying those are like one time payment.
I have other subscription payment.
So I may have already stored payment methods which were used for single time payment.
Now I am switching payment method to one of the stored payment method
woeful turret
Generally, if the PaymentMethod wasn't created with SetupIntents or PaymentIntents with setup_future_usage parameter, it should only be used once.
So you have to ask your customers to add a new PaymentMethod with one of those methods/parameters
dusky quartz
ok
is there any programming way to generate link https://docs.stripe.com/billing/subscriptions/update-payment-method ?
woeful turret
Yes, using SetupIntents (or Stripe Checkout with mode=setup) and calling update Subscription API to set default_payment_method.
