How Stripe Payments Work
The Payment Flow
Customer Journey:
┌─────────────────────────────────────────────────────────────────┐
│ │
│ 1. Browse 2. Add to 3. Checkout 4. Enter 5. Pay │
│ Products Cart Card │
│ │
│ [🛍️] → [🛒] → [📋] → [💳] → [✅] │
│ │
└─────────────────────────────────────────────────────────────────┘
Behind the Scenes:
┌─────────────────────────────────────────────────────────────────┐
│ │
│ 1. Create 2. Collect 3. Confirm 4. Webhook │
│ Payment Card Payment Updates │
│ Intent Data Database │
│ │
│ [Backend] → [Stripe.js] → [Stripe] → [Backend] │

└─────────────────────────────────────────────────────────────────┘
Security Architecture
Card data NEVER touches your server:
- Customer enters card details in Stripe Elements
- Stripe.js tokenizes the data client-side
- Only a secure token is sent to your backend
- Your backend uses the token with Stripe API
- Payment is processed on Stripe's PCI-compliant servers
This architecture means zero PCI compliance burden for you.

Webhook Integration
Why Webhooks Matter
Webhooks ensure your database stays synchronized with Stripe:
Payment Events:
├── payment_intent.succeeded → Create order, send confirmation
├── payment_intent.failed → Notify customer, log failure
├── charge.refunded → Update order status, notify customer
└── customer.subscription.* → Handle subscription changes
Setting Up Webhooks
For Local Development (Stripe CLI):
# Install Stripe CLI
brew install stripe/stripe-cli/stripe
# Login to your Stripe account
stripe login
# Forward webhooks to your local server
stripe listen --forward-to localhost:8001/api/webhooks/stripe
For Production:
- Go to Developers > Webhooks in Stripe Dashboard
- Add endpoint:
https://yourdomain.com/api/webhooks/stripe - Select events to listen for
- Copy the webhook signing secret
Webhook Handler
Your application verifies and processes webhooks:
Webhook Processing:
1. Receive POST request from Stripe
2. Verify signature (prevent tampering)
3. Parse event type
4. Process based on event:
- payment_intent.succeeded → Fulfill order
- payment_intent.failed → Alert customer
- charge.refunded → Update records
5. Return 200 OK to acknowledge
