Stripe Subscriptions Update/Downgrade/

So I have an app that has a backend in Xano and multiple options for Stripe subscriptions. How do I handle updating/downgrading/cancelling a subscription?
Any tips help

Depending on your setup you’ll probably need to study the Stripe API and use it via Xano to trigger these changes upon user prompt or specific events.

Stripe has a customer portal you can use.
