Stripe: How to get shipping fee


I’ve got a scenario, in which someone bought a book and has to pay for shipping, too.
Somehow the stripe-data doesn’t mention that shipping-fee.

By an http-request I am able to find the shipping fee.
But when I do an API-Call the shipping fee still is not mentioned …
Any Idea?

Best regards,
