|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### 1. Install Dependencies
|
||||
```bash
|
||||
npm install stripe
|
||||
# (Already done, but shown for reference)
|
||||
```
|
||||
|
||||
### 2. Set Up Stripe Account
|
||||
Visit https://dashboard.stripe.com and:
|
||||
- Create account
|
||||
- Get API Secret Key (starts with `sk_test_` or `sk_live_`)
|
||||
- Get Publishable Key (starts with `pk_test_` or `pk_live_`)
|
||||
- Create webhook endpoint pointing to `/api/billing/webhook`
|
||||
- Get webhook signing secret (starts with `whsec_`)
|
||||
|
||||
### 3. Create Stripe Prices
|
||||
In Stripe Dashboard > Products:
|
||||
- **Starter**: £39/month recurring
|
||||
- **Growth**: £99/month recurring
|
||||
- **Pro**: £249/month recurring
|
||||
|
||||
Copy each Price ID (starts with `price_`)
|
||||
|
||||
### 4. Update .env
|
||||
```bash
|
||||
# Replace placeholders with real values:
|
||||
STRIPE_SECRET_KEY=sk_test_abc123...
|
||||
STRIPE_PUBLISHABLE_KEY=pk_test_abc123...
|
||||
STRIPE_WEBHOOK_SECRET=whsec_abc123...
|
||||
STRIPE_PRICE_STARTER=price_abc123...
|
||||
STRIPE_PRICE_GROWTH=price_def456...
|
||||
STRIPE_PRICE_PRO=price_ghi789...
|
||||
```
|
||||
|
||||
### 5. Initialize Database
|
||||
```bash
|
||||
node init-db.js
|
||||
```
|
||||
|
||||
Creates `subscriptions` table and indexes.
|
||||
|
||||
### 6. Start Server
|
||||
```bash
|
||||
npm start
|
||||
# Server runs on port 3456
|
||||
```
|
||||
|
||||
### 7. Test Integration
|
||||
```bash
|
||||
# Use Stripe CLI for local testing
|
||||
stripe listen --forward-to localhost:3456/api/billing/webhook
|
||||
|
||||
# In another terminal, create test checkout
|
||||
curl -X POST http://localhost:3456/api/billing/checkout \
|
||||
-H "Authorization: Bearer YOUR_JWT_TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"plan": "starter",
|
||||
"successUrl": "https://app.example.com/success",
|
||||
"cancelUrl": "https://app.example.com/cancel"

## 🎯 API Endpoints
|
||||
|
||||
All endpoints protected with JWT authentication (except webhooks which use signature verification).
|
||||
|
||||
### POST /api/billing/checkout
|
||||
Initiate checkout flow for a subscription plan.
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:3456/api/billing/checkout \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"plan": "growth",
|
||||
"successUrl": "https://app.example.com/success",
|
||||
"cancelUrl": "https://app.example.com/cancel"
|
||||
}'
|
||||
```
|
||||
|
||||
**Response:** `{ "sessionId": "...", "url": "https://checkout.stripe.com/..." }`
|
||||
|
||||
### POST /api/billing/webhook
|
||||
Stripe sends webhook events to this endpoint. Do not call directly.
|
||||
|
||||
**Events Handled:**
|
||||
- `checkout.session.completed` - Creates subscription
|
||||
- `customer.subscription.updated` - Updates subscription
|
||||
- `customer.subscription.deleted` - Cancels subscription
|
||||
- `invoice.payment_failed` - Logs failure
|
||||
|
||||
### GET /api/billing/subscription
|
||||
Get current subscription status.
|
||||
|
||||
```bash
|
||||
curl -X GET http://localhost:3456/api/billing/subscription \
|
||||
-H "Authorization: Bearer $TOKEN"
|
||||
```
|
||||
|
||||
**Response:** Subscription object or null if no subscription.
|
||||
|
||||
### POST /api/billing/portal
|
||||
Create Stripe Customer Portal session for managing subscription.
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:3456/api/billing/portal \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{ "returnUrl": "https://app.example.com/billing" }'
|
||||
```
|
||||
|
||||
**Response:** `{ "url": "https://billing.stripe.com/session/..." }`
|
||||

|
||||
## 🔐 Security Features
|
||||
|
||||
✓ **Webhook Signature Verification** - Validates Stripe authenticity
|
||||
✓ **JWT Authentication** - Protects billing endpoints
|
||||
✓ **Parameterized Queries** - Prevents SQL injection
|
||||
✓ **Stripe Checkout** - PCI compliance (no card data handling)
|
||||
✓ **Rate Limiting** - 100 requests per 15 minutes per IP
|
||||
✓ **HTTPS Enforced** - Production deployment requires HTTPS

## 🗄️ Database Schema
|
||||
|
||||
### subscriptions table
|
||||
```sql
|
||||
- id (PRIMARY KEY)
|
||||
- user_id (UNIQUE, FOREIGN KEY to users)
|
||||
- stripe_customer_id (UNIQUE)
|
||||
- stripe_subscription_id
|
||||
- plan (starter|growth|pro)
|
||||
- status (active|trialing|past_due|cancelled)
|
||||
- trial_start, trial_end
|
||||
- current_period_start, current_period_end
|
||||
- cancel_at_period_end
|
||||
- created_at, updated_at
|
||||
```
|
||||
|
||||
Indexes on `user_id` and `stripe_customer_id` for fast lookups.
|
||||
|
||||

|
||||
|
||||
## ⚙️ Middleware
|
||||
|
||||
### attachSubscription(pool)
|
||||
Auto-attaches subscription info to authenticated requests.
|
||||
|
||||
```javascript
|
||||
// In server.js:
|
||||
app.use('/api/', attachSubscription(pool));
|
||||
|
||||
// Then in handlers:
|
||||
// req.subscription contains subscription data
|
||||
```
|
||||
|
||||
### requireActiveSubscription
|
||||
Restricts endpoint to active subscribers only.
|
||||
|
||||
```javascript
|
||||
app.get('/api/premium', verifyToken, requireActiveSubscription, handler);
|
||||
```
|
||||
|
||||
### requireFreeOrSubscription
|
||||
Allows free tier OR active subscribers (useful for core features).
|
||||
|
||||
```javascript
|
||||
app.get('/api/tenders', verifyToken, requireFreeOrSubscription, handler);
|
||||
```

|

|
||||
|
||||
## 🔧 Troubleshooting
|
||||
|
||||
### "STRIPE_SECRET_KEY is not set"
|
||||
→ Check `.env` - replace `sk_test_placeholder` with real key
|
||||
|
||||
### "Webhook signature verification failed"
|
||||
→ Check `STRIPE_WEBHOOK_SECRET` in `.env` - must match webhook secret from Stripe Dashboard
|
||||
|
||||
### "No subscription found for user"
|
||||
→ User hasn't completed checkout yet. Use test card 4242 4242 4242 4242
|
||||
|
||||
### "Invalid plan: unknown"
|
||||
→ Check plan parameter - must be: `starter`, `growth`, or `pro`
|
||||
|
||||
### Webhooks not received
|
||||
→ Check Stripe Dashboard > Webhooks > Event Logs for failures
|
||||
→ Ensure production URL is correct if not using localhost
|
||||
→ Use Stripe CLI for local testing: `stripe listen --forward-to localhost:3456/api/billing/webhook`
