Quick Start
javascript
// Frontend - PayPal Smart Buttons
<div id="paypal-button-container"></div>
<script src="https://www.paypal.com/sdk/js?client-id=YOUR_CLIENT_ID¤cy=USD"></script>
<script>
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
value: '25.00'
}
}]
});
},
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
// Payment successful
console.log('Transaction completed by ' + details.payer.name.given_name);
// Send to backend for verification
fetch('/api/paypal/capture', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify({orderID: data.orderID})
});
});
}
}).render('#paypal-button-container');
</script>python
# Backend - Verify and capture order
from paypalrestsdk import Payment
import paypalrestsdk
paypalrestsdk.configure({
"mode": "sandbox", # or "live"
"client_id": "YOUR_CLIENT_ID",
"client_secret": "YOUR_CLIENT_SECRET"
})
def capture_paypal_order(order_id):
"""Capture a PayPal order."""
payment = Payment.find(order_id)
if payment.execute({"payer_id": payment.payer.payer_info.payer_id}):
# Payment successful
return {
'status': 'success',
'transaction_id': payment.id,
'amount': payment.transactions[0].amount.total
}
else:
# Payment failed
return {
'status': 'failed',
'error': payment.error

Testing
python
# Use sandbox credentials
SANDBOX_CLIENT_ID = "..."
SANDBOX_SECRET = "..."
# Test accounts
# Create test buyer and seller accounts at developer.paypal.com
def test_payment_flow():
"""Test complete payment flow."""
client = PayPalClient(SANDBOX_CLIENT_ID, SANDBOX_SECRET, mode='sandbox')
# Create order
order = client.create_order(10.00)
assert 'id' in order
# Get approval URL
approval_url = next((link['href'] for link in order['links'] if link['rel'] == 'approve'), None)
assert approval_url is not None
# After approval (manual step with test account)
# Capture order
# captured = client.capture_order(order['id'])
# assert captured['status'] == 'COMPLETED'
