you need to retrieve the CheckoutSession object and expand the line_items field , there is this blog post on the overall approach : https://dev.to/stripe/purchase-fulfilment-with-checkout-or-wait-what-was-i-paid-for-335d

we also touch on it in https://stripe.com/docs/payments/checkout/fulfill-orders#fulfill .
overall the details of the products/quantities are in the line_items of the CheckoutSession. https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-line_items-data
