nash - user upgrades

That sounds like this scenario to me: https://stripe.com/docs/payments/payment-intents/upgrade-to-handle-actions#update-server

How are the payment methods associated with the customers?

Through paymentintent creation

We pass the customer id.

If it's just a card udpate, through setupintent.

Okay. Are these stored cards already or are you bringing them on-session?

[crystal juniper]

When they decide to upgrade?

[hybrid spear]

Right. In that case I would attempt the this step first: https://stripe.com/docs/payments/payment-intents/upgrade-to-handle-actions#update-client

If that doesn't work then circle back and have them re-enter card details using a Stripe Element
