+# PayPal Payments
+
+PayPal is available as a payment method alongside Stripe and crypto (XMR/DOGE).
+
+## Shop Setup
+
+1. Go to https://developer.paypal.com/dashboard/
+2. Create an app (sandbox for testing, live for production)
+3. Copy Client ID and Secret
+4. In Shop Settings → PayPal Settings, enter credentials and save
+
+## Configuration
+
+Global settings in `development.ini`:
+
+```ini
+app.payments.paypal.enabled = True
+app.paypal.sandbox_mode = True
+```
+
+Or environment variables:
+
+```bash
+export MPS_PAYMENTS_PAYPAL_ENABLED=True
+export MPS_PAYPAL_SANDBOX_MODE=True
+```
+
+## How It Works
+
+- Each shop configures their own PayPal credentials
+- PayPal button appears at checkout when enabled
+- Payment info stored on Invoice (`paypal_order_id`, `paypal_capture_id`)
+- `Invoice.payment_method` returns "paypal" for PayPal payments
+- Saved payment methods stored in `PayPalUserShop`
+
+## Routes
+
+- `POST /paypal/create-order/{cart_id}` - Creates PayPal order (called by JS SDK)
+- `POST /paypal/complete-checkout/{cart_id}` - Captures payment, creates invoice
+- `POST /webhooks/paypal` - Webhook handler for payment events
+
+## Database
+
+**mps_shop columns:**
+- `paypal_client_id` - Shop's PayPal Client ID
+- `paypal_secret` - Shop's PayPal Secret
+- `paypal_enabled` - Toggle PayPal on/off
+
+**mps_invoice columns:**
+- `paypal_order_id` - PayPal order reference
+- `paypal_capture_id` - PayPal capture reference
+
+**mps_paypal_user_shop table:**
+- Tracks saved PayPal payment methods per user/shop
