savePaymentMethod

If the PaymentIntent has a payment_method and a customer or if you’re attaching a payment method to the PaymentIntent in this request, you can pass save_payment_method=true to save the payment method to the customer. Defaults to false.

If the payment method is already saved to a customer, this does nothing. If this type of payment method cannot be saved to a customer, the request will error.

See save_payment_method.
