Updating credit card: - We have an openBillingPortal() function that when called, will redirect a user to the Stripe billing portal where they can update their card info. If it's a valid card, we allow the change and keep the customer in an active subscription state.

Past invoices: - We have a GET /customer method that returns all billing related information on a user. This includes their current plans, features and balances they have available, and can take in an expand?=invoices param that will return all past invoice data for you to display.

Users can also see invoice history in the Stripe billing portal mentioned above.
