stripe-shop-integration（Stripe shop 集成）

Stripe E-Commerce Shop Integration

Production-tested patterns for integrating Stripe payments into React e-commerce applications with Supabase backend. Supports both Vite and Next.js. All examples use UK GBP currency and follow enterprise security standards.

Framework Support

Quick Start Checklist

1. Install Dependencies: npm install @stripe/stripe-js @stripe/react-stripe-js stripe
2. Environment Variables: Set up .env with Stripe keys
3. Create Client Library: src/lib/stripe.ts
4. Create Server Library: src/lib/stripe-server.ts
5. Create API Endpoints: api/stripe/ directory
6. Create Types: src/types/stripe.ts
7. Set Up Webhook: Configure in Stripe Dashboard

Stripe MCP Server (AI Agent Integration)

For AI-assisted Stripe management, use the official Stripe MCP server:

Installation

# Add to Claude Code MCP config (~/.claude.json)
claude mcp add --scope user stripe -- npx -y @stripe/mcp --tools=all --api-key=sk_test_YOUR_KEY

Manual Configuration

{
  "mcpServers": {
    "stripe": {
      "command": "npx",
      "args": [
        "-y",
        "@stripe/mcp",
        "--tools=all",
        "--api-key=sk_test_YOUR_STRIPE_SECRET_KEY"
      ]
    }
  }
}

MCP Capabilities

The Stripe MCP enables natural language interactions:

• Create and manage products/prices
• Handle customer operations
• Process payments and refunds
• Search Stripe documentation
• Debug webhook issues
• Manage subscriptions

Documentation: https://docs.stripe.com/mcp

Key Principles

Security First

• NEVER expose secret keys on the client
• ALWAYS validate amounts server-side against database
• ALWAYS use webhook signature validation
• ALWAYS store payment records in database

UK/GBP Configuration

• Currency: 'gbp'
• Country: 'GB'
• Amounts in pence for Stripe API (multiply pounds by 100)

Two Payment Methods

1. Payment Intent (Embedded Form)

- Payment form stays on your site - More control over UI/UX - Use PaymentElement component

1. Checkout Session (Stripe Hosted)

- Redirects to Stripe's hosted page - Easier to implement - Built-in address collection

Common Commands

# Install Stripe packages
npm install @stripe/stripe-js @stripe/react-stripe-js stripe

# Install Stripe CLI (macOS)
brew install stripe/stripe-cli/stripe

# Login to Stripe CLI
stripe login

# Generate TypeScript types from Supabase (if using)
npx supabase gen types typescript --project-id YOUR_PROJECT_ID > src/types/supabase.ts

Testing

• Use Stripe test mode keys (start with pk_test_ and sk_test_)
• Test card number: 4242 4242 4242 4242
• Any future expiry date and any 3-digit CVC
• Use Stripe CLI for webhook testing: stripe listen --forward-to localhost:3000/api/stripe/webhook
