# Stripe Payments Integration - Summary

## What Was Built

### Backend

1. **Stripe Server Utility** (`src/lib/stripe/server.ts`)
   - Stripe client initialization
   - Helper functions for creating PaymentIntents
   - Webhook signature verification

2. **Payment Creation API** (`src/app/api/payments/create/route.ts`)
   - Creates Stripe PaymentIntent
   - Stores payment record in database
   - Returns client secret to frontend
   - Rate limited (10 requests per 15 minutes)

3. **Stripe Webhook Handler** (`src/app/api/webhooks/stripe/route.ts`)
   - Handles `payment_intent.succeeded` - Updates match to hired, sends notification
   - Handles `payment_intent.payment_failed` - Allows retry
   - Handles `payment_intent.canceled` - Removes pending payment

### Frontend

1. **Stripe Provider** (`src/components/payment/StripeProvider.tsx`)
   - Wraps app with Stripe Elements
   - Configures appearance to match app theme

2. **Payment Form** (`src/components/payment/PaymentForm.tsx`)
   - Stripe PaymentElement for card input
   - Handles payment confirmation
   - Error and loading states

3. **Hire Payment Modal** (`src/components/payment/HirePaymentModal.tsx`)
   - Modal triggered on hire button click
   - Manages payment flow states
   - Integrates with Stripe Elements

4. **Payment Success Page** (`src/app/(authenticated)/contractor/payment-success/page.tsx`)
   - Handles redirect after 3D Secure or async payment
   - Shows confirmation to user

5. **Updated Contractor Matches Page**
   - Hire button now opens payment modal
   - Payment processed before marking as hired
   - Success updates UI to show hired state

## Environment Variables Required

```bash
# Add to .env.local
STRIPE_SECRET_KEY=sk_test_...
STRIPE_PUBLISHABLE_KEY=pk_test_...
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...
NEXT_PUBLIC_APP_URL=http://localhost:3000
```

## Stripe Setup Instructions

### 1. Create Stripe Account
- Sign up at https://stripe.com
- Get test API keys from https://dashboard.stripe.com/test/apikeys

### 2. Configure Environment Variables
Add the keys to `.env.local` (see above)

### 3. Set Up Webhook Endpoint
- In Stripe Dashboard → Developers → Webhooks
- Add endpoint: `https://your-domain.com/api/webhooks/stripe`
- Select events:
  - `payment_intent.succeeded`
  - `payment_intent.payment_failed`
  - `payment_intent.canceled`
- Copy webhook signing secret to `STRIPE_WEBHOOK_SECRET`

### 4. Test the Flow
Use Stripe test cards:
- **Success**: `4242 4242 4242 4242`
- **Decline**: `4000 0000 0000 0002`
- **3D Secure**: `4000 0025 0000 3155`
- Any future expiry date, any 3-digit CVC

## Payment Flow

1. Contractor clicks "Hire — $50 Fee"
2. Payment modal opens
3. Backend creates PaymentIntent with Stripe
4. Contractor enters card details
5. Stripe processes payment
6. Webhook confirms success
7. Match marked as 'hired'
8. Worker receives notification

## Security Considerations

- ✅ Stripe Elements used for PCI compliance
- ✅ Webhook signatures verified
- ✅ Rate limiting on payment endpoints
- ✅ No card details touch our servers
- ✅ Service role used for database updates

## Next Steps for Production

1. Switch to Stripe production keys
2. Set up production webhook endpoint
3. Add payment receipt emails
4. Consider saved payment methods for repeat hires
5. Add payment history page for contractors
