When & Why to Use This Skill

This Claude skill offers a ready-to-use Stripe Checkout integration for Express.js, specifically designed for handling one-time payments. It streamlines the development process by automatically generating sample products in Stripe if none are configured, and it eliminates the immediate need for complex webhook setups, making it an efficient solution for developers looking to monetize web applications quickly.

Use Cases

  • Rapidly deploying a payment gateway for digital products, such as e-books or software licenses, using a pre-configured Express.js template.
  • Prototyping e-commerce checkout flows with automated product creation to test user experience before manual Stripe dashboard setup.
  • Integrating secure, PCI-compliant credit card processing into a Node.js backend with minimal configuration and clear deployment paths for Vercel or Netlify.

Stripe One-Time Payment

Stripe Checkout integration for accepting one-time payments. No webhook configuration required.

Tech Stack

  • Backend: Express.js
  • Payments: Stripe Checkout
  • Language: JavaScript
  • Package Manager: npm
  • Port: 4242

Setup

1. Clone the Template

git clone --depth 1 https://github.com/Eng0AI/stripe-one-time-payment.git .

If the directory is not empty:

git clone --depth 1 https://github.com/Eng0AI/stripe-one-time-payment.git _temp_template
mv _temp_template/* _temp_template/.* . 2>/dev/null || true
rm -rf _temp_template

2. Remove Git History (Optional)

rm -rf .git
git init

3. Install Dependencies

npm install

4. Setup Environment Variables

cp .env.example .env

Required:

  • STRIPE_SECRET_KEY - Your Stripe secret key (sk_test_xxx)
  • STRIPE_PUBLISHABLE_KEY - Your Stripe publishable key (pk_test_xxx)

Optional:

  • PRICE - Price ID from Stripe Dashboard. If not set, a $20 sample product will be auto-created.

5. Start the Server

npm start

Server runs at http://localhost:4242. If PRICE is not set, it auto-creates a sample product.

Deploy to Vercel

Step 1: Create Serverless API Wrapper

Create api/index.js with the Stripe checkout logic (see full deploy guide).

Step 2: Create Vercel Config

Create vercel.json:

{
  "version": 2,
  "buildCommand": "",
  "outputDirectory": "client/html",
  "rewrites": [
    { "source": "/config", "destination": "/api" },
    { "source": "/checkout-session", "destination": "/api" },
    { "source": "/create-checkout-session", "destination": "/api" }
  ]
}

Step 3: Set Environment Variables

printf "YOUR_SECRET_KEY" | vercel env add STRIPE_SECRET_KEY production -t $VERCEL_TOKEN
printf "YOUR_PUBLISHABLE_KEY" | vercel env add STRIPE_PUBLISHABLE_KEY production -t $VERCEL_TOKEN

Step 4: Deploy

vercel --prod -t $VERCEL_TOKEN --yes

Deploy to Netlify

Create netlify/functions/api.js and netlify.toml with similar configuration, then:

netlify deploy --prod

Testing

Use test card numbers:

  • Success: 4242 4242 4242 4242
  • Decline: 4000 0000 0000 0002

Any future expiry date and any 3-digit CVC will work.

Going Live

  1. Replace test keys with live keys (sk_live_/pk_live_)
  2. Create products in Stripe Dashboard Live mode
  3. Complete Stripe account verification (KYC)
  4. Test with a real payment
