AV - subscription billing method

[jolly apex]

There are three places that you might have this set:

1. Default payment method on the subscription https://stripe.com/docs/api/subscriptions/update#update_subscription-default_payment_method

2. Default payment method on the Customer https://stripe.com/docs/api/customers/object#customer_object-invoice_settings-default_payment_method

3. Default source on the customer https://stripe.com/docs/api/customers/object#customer_object-default_source

thanks, I've seen these articles, but was wondering if there was a way to change the property directly. But after looking it seems when the default_payment_method on the subcription is null, the billing method is changed to use the default card automatically

Yes, it sounds like you probably have the default set via #2 or #3 there. Stripe will use those defaults on any subscription that doesn't has no default_payment_method

And, as you note, that default_payment_method field on the subscription will override the default on the customer
