## What it does

The skill fires when you ask for payments, billing, subscriptions or a Stripe integration. The agent installs `stripe` and `@stripe/stripe-js`, adds `STRIPE_SECRET_KEY`, `NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY` and `STRIPE_WEBHOOK_SECRET`, then creates a client module at `lib/stripe.ts` with a pinned API version.

From there it builds a checkout API route, a `POST /api/webhooks/stripe` handler that verifies the signature with `stripe.webhooks.constructEvent`, and handlers for `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted` and `invoice.payment_failed`. Subscription status goes into your database. The billing portal and pricing page are marked optional.

All three Stripe keys have to exist before anything runs, or the client fails to construct. For local webhook testing the notes point to `stripe listen --forward-to localhost:3000/api/webhooks/stripe`. The skill also tells you to keep the Stripe customer ID in your user table so repeat buyers don't get duplicate customers, and to pull prices with `stripe.prices.list` instead of hardcoding them.

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/adding-stripe/SKILL.md

## When to use it
- wire Stripe Checkout into a web app
- sell one-time payments and subscriptions from the same session
- verify incoming webhook signatures instead of trusting raw payloads
- keep subscription status in sync in your database
- let customers cancel or change a plan in the billing portal

## Example prompts
- add Stripe subscription payments to my pricing page
- create the /api/webhooks/stripe handler and update subscription status in the database
- hook up the customer portal so users can cancel on their own

# Add Stripe Payments

Use this skill when the user asks to add payments, billing, subscriptions, or Stripe integration.

## Steps

1. **Install the SDK**

   ```bash
   npm install stripe @stripe/stripe-js
   ```

2. **Add environment variables**

   ```
   STRIPE_SECRET_KEY=sk_test_...
   NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_test_...
   STRIPE_WEBHOOK_SECRET=whsec_...
   ```

3. **Create a Stripe client module** — create `lib/stripe.ts`:

   ```ts
   import Stripe from "stripe";

   export const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!, {
     apiVersion: "2024-12-18.acacia",
   });
   ```

4. **Create a checkout API route** — create an endpoint that creates a Stripe Checkout session:

   ```ts
   const session = await stripe.checkout.sessions.create({
     mode: "subscription", // or "payment" for one-time
     payment_method_types: ["card"],
     line_items: [{ price: priceId, quantity: 1 }],
     success_url: `${origin}/success?session_id={CHECKOUT_SESSION_ID}`,
     cancel_url: `${origin}/pricing`,
     customer_email: userEmail,
   });
   return redirect(session.url!);
   ```

5. **Create a webhook handler** — create a `POST` endpoint at `/api/webhooks/stripe`:

   - Verify the webhook signature using `stripe.webhooks.constructEvent`.
   - Handle key events: `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted`, `invoice.payment_failed`.
   - Update your database with the subscription status.

6. **Add customer portal (optional)** — create an endpoint that redirects to `stripe.billingPortal.sessions.create` so users can manage their subscription.

7. **Add pricing page UI** — create a pricing page with plan cards that call the checkout API route.

## Notes

- Always verify webhook signatures — never trust unverified payloads.
- Use Stripe CLI (`stripe listen --forward-to localhost:3000/api/webhooks/stripe`) for local webhook testing.
- Store the Stripe customer ID in your user database to avoid creating duplicate customers.
- Use `stripe.prices.list` to fetch prices dynamically instead of hardcoding them.
