One thing that comes to mind is that you can add {CHECKOUT_SESSION_ID} to those url parameters. Stripe will replace that with the actual Checkout Session's ID which you can use to look up the data on the session itself https://stripe.com/docs/payments/checkout/custom-success-page#modify-success-url
