One Time Payments

• Create a new product and copy the price ID price_1ju5GD464564 in config.stripe.plans[0].priceId in to the config.ts file.
• In your Developers → API keys, copy your public & private keys and add them to the STRIPE_SECRET_KEY & STRIPE_PUBLIC_KEY in .env.local file.
• To set up the webhook locally, follow the steps in Developers → Webhooks → Test in local environment. After login to Stripe CLI, use this command to forward webhook events to our API:

1stripe listen --forward-to localhost:3000/api/webhook/stripe

Copy the signing secret and add it to STRIPE_WEBHOOK_SECRET in .env.local file.

Subscriptions

Let's create a Stripe Checkout to set up a subscription and let our webhook handle the logic to provision access to the user.

You need to have both Stripe & Database to complete this.

• In your Stripe dashboard, Click [More +] → [Product Catalogue] → [+ Add Product]. Set a name and a monthly price (or anything according to your business model). Then click [Save Product].
• In the [Pricing] section, copy the product price ID (starts with price_) and add it to the first plan in the stripe.plans array in the config.ts file.
• In /app/dashboard/page.tsx, paste this:

/app/dashboard/page.tsx

1import ButtonAccount from "@/components/ButtonAccount";
2import ButtonCheckout from "@/components/ButtonCheckout";
3import config from "@/config";
4
5export const dynamic = "force-dynamic";
6
7export default async function Dashboard() {
8  return (
9    <main className="min-h-screen p-8 pb-24">
10      <section className="mx-auto max-w-xl space-y-8">
11        <ButtonAccount />
12
13        <h1 className="text-3xl font-extrabold md:text-4xl">
14          Subscribe to get access:
15        </h1>
16
17        <ButtonCheckout
18          mode="subscription"
19          priceId={config.stripe.plans[0].priceId}
20        />
21      </section>
22    </main>
23  );
24}

• Open http://localhost:3000/dashboard in your browser, log-in and click the button to make a payment with the credit card number 4242 4242 4242 4242 expiry date set to a future date and a random CVV number.
• Our webhook /app/api/webhook/stripe/route.ts listens to Stripe events and will handle the logic to provision access (or not) to the user—See the Boolean hasAccess in the User.ts schema (NextAuth) or has_access in your Supabase profiles table.

You need to have a Stripe local endpoint running on your computer for this to work in dev mode.

• You can add your own logic in /app/api/webhook/stripe/route.ts like sending abandoned cart emails, remove credits, etc.
• Users can manage their account with:

/app/dashboard/page.tsx

1<ButtonAccount /> // (cancel subscription, update credit card, etc.)

That's it. You can build your SaaS on top of this flow!

Create Checkout

From the front-end, use theButtonCheckout component to automatically create a checkout session (one-time payment or subscription).

Stripe Webhooks

Our API listens to Stripe selected webhooks events & update the user accordingly. It turns boolean hasAccess (or has_access in Supabase) to true/false based on whether the user should have access to a paid resource or not.

You can add your own business logic to the /app/api/webhook/stripe/route.ts API endpoint (add credits to a user, send email with a paid e-book etc.)

Production Checklist

• Turn OFF Test Mode in your Stripe Dashboard
• In your Developers → API keys copy your public & private keys and add them to STRIPE_SECRET_KEY & STRIPE_PUBLIC_KEY in your production environment variables.
• In your Developers → Webhook → Add Endpoint. Set your domain + /api/webhook/stripe (i.e example.com/api/webhook/stripe). Select checkout.session.completed event (or more if needed). Copy the signing secret and add it to STRIPE_WEBHOOK_SECRET in your production environment variables.
• Optional: In Settings → Business → Bank accounts and currencies, set a specific date of the month to receive your payouts (I use the 10th of each month)
• Optional: In Settings → Business → Customer Emails, activate emails for successful payments & refunds
