Hi there
If you set that property to automatic, then you'll rely on Stripe SCA Engine to automatically prompt your customers for authentication based on risk level and other requirements.

If you want to trigger 3ds for every transaction meets SCA requirement then you need to set that property to any. However we strongly recommend to use automatic.
