Hi, taking a look at our documents here

1/ The above flow you have would work. You'd pass the shipping rate create: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-shipping_options-shipping_rate pr pass the shipping rate data directly: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-shipping_options-shipping_rate_data

No recommendations here

2/ You can use product metadata for tracking product inventory, sure!

Perfect not having to create a shipping rate before making the session is news to me, appreciate it! In regards for the external shipping platform, do you happen to know which one is the most popular?
