Update credit card for Stripe Customer

I want to send my existing Stripe Customer a form to update their credit card used for subscription payments. What is the best way to do this without creating a new customer?

Did you mean you have customers who filled out your form to avail of your subscriptions and you want to send them new forms for them to be able to update credit cards to be used as payment for those subscriptions? Unfortunately, it is not currently possible. Our Stripe integration currently facilitates selling of subscriptions only.

However, if you mean something else, please give us more details so we can further check your requirement.

You are correct, that is what I am looking for.

Unfortunately, it cannot be done yet. You might need to cancel the existing subscriptions and give them the form where you are selling the subscriptions again.
