In this episode, we kick off the checkout flow by wiring up everything needed so users can buy products via Stripe. We start by setting up a new checkout route and controller, which handles the heavy lifting. Then, we update our product page so the "Buy" button actually posts to the newly created checkout route.
Inside the controller, we dive into setting up a Stripe Checkout session dynamically since our products live in our app (not hardcoded in Stripe). We carefully pass along the necessary details: product name, description, price, and handle the fee we (as the platform) want to charge per sale. There's a handy bit where we create an applicationFeeAmount
method on the product model so we can re-use that logic everywhere we need it.
You'll see how to embed important metadata for later use, like the product ID, and how to redirect the buyer straight to Stripe's checkout page. We confirm everything works by doing a live test payment and seeing the whole flow in action—including being redirected to the success page when done.
At the end, we mention that while everything appears to work smoothly, the app doesn't yet know about the purchase itself—Stripe handles that. Next time, we'll set up a webhook so the app can react when a purchase comes in, make sale records, and send emails. So, this episode is all about laying the groundwork for a super slick, multi-tenant checkout experience!
