Hi! You have two options:

• Update the default_payment_method of the subscription: https://stripe.com/docs/api/subscriptions/update#update_subscription-default_payment_method
• Or update the invoice_settings.default_payment_method of the customer https://stripe.com/docs/api/customers/update#update_customer-invoice_settings-default_payment_method

But how do you know when to change?

How can I detect that there was a difference in the payment method and change it?

generally you would know it's changed since you had some API calls to collect and set the method, so I don't quite follow. But there is for example a payment_method.attached event so maybe that is useful https://stripe.com/docs/api/events/types#event_types-payment_method.attached

I will try to explain my situation better.

My subscription model:

1st step: Create the customer without payment data

Step 2: Create the signature

3rd step: I collect the payment data and validate it with confirmCardPayment

Then I monitor the subscription_create event and set the payment method as default.

I'm having difficulty just with the subscription_cycle event, how to detect that there was a credit card change and set this new medium as default?

In a new subscription cycle, if stripe is unable to charge the old credit card, I use confirmCardPayment to collect a new payment method
