title: Django - Restrict Stripe SuccessUrl access
body: <p>I have just integrated Stripe Checkout with my Django app. However, from their code:</p>
  
  <pre><code> session = stripe.checkout.Session.create(
          customer_email=customer.email,
          payment_method_types=['card'],
          line_items=line_items,
  
          mode='payment',
          success_url='http://127.0.0.1:8000/SUCCESS/?session_id={CHECKOUT_SESSION_ID}',
          cancel_url='http://127.0.0.1:8000/cart'
          )
  </code></pre>
  
  <p>It redirects to a Success_url. I would like to display their order info and send an email from the success page but currently, everyone can visit(would cause random emails etc). Is there a way i can limit this for the person that just checked out? Thank you!</p>
