Hello

When you create the Sub you want to set payment_settings.save_default_payment_method: https://stripe.com/docs/api/subscriptions/create#create_subscription-payment_settings-save_default_payment_method

That will auto save the paymnetmethod as the default

[unreal adder]

so this will automatically do it when the first subscription is created, without any further action needed?

what if, this is a second subscription (in case business rules at a later time would allow more then 1 sub).. would this potentially switch the card to the new default... or
assuming that the same default card would be used anyway.. no harm would be done..

I mean.. coudl this have negative influence if used more then one time in the lifetime of a customer?

I'm not sure exactly what you mean. But if you want to use the already collected card for a new Sub for that Customer then you would just create the Sub and set it as the default_payment_method and you don't have to collect card details again.
