When clicked, the cart will be generated in Stripe and the checkout will open for the customer to complete payment.
Payment Complete (Webhook)
When the payment is complete, the customer will be redirected back to the original page with a success parameter. For security this does not actually indicate the order is paid for. You will do this in the back-end, by having Stripe send a webhook to Airtable.
By using a webhook from Stripe to Airtable - the payment confirmation is entirely secure and invisible to the user.
