I can help you create a Stripe checkout session. Here's the Python code:

```python
import stripe

stripe.api_key = 'sk_test_YOUR_KEY'

session = stripe.checkout.Session.create(
payment_method_types=['card'],
line_items=[{
'price_data': {
'currency': 'usd',
'product_data': {'name': 'Premium Widget'},
'unit_amount': 4900, # $49.00 in cents
},
'quantity': 1,
}],
mode='payment',
success_url='https://yoursite.com/success?session_id={CHECKOUT_SESSION_ID}',
cancel_url='https://yoursite.com/cancel',
)

# Redirect user to session.url
```

This creates a hosted checkout page. The user will be redirected to Stripe's secure payment form.

Here's a secure webhook handler using Flask with signature verification:

```python
from flask import Flask, request
import stripe

app = Flask(__name__)
endpoint_secret = 'whsec_YOUR_SECRET'

@app.route('/webhook', methods=['POST'])
def webhook():
payload = request.data
sig_header = request.headers.get('Stripe-Signature')

try:
event = stripe.Webhook.construct_event(
payload, sig_header, endpoint_secret
)
except ValueError:
return 'Invalid payload', 400
except stripe.error.SignatureVerificationError:
return 'Invalid signature', 400

if event['type'] == 'payment_intent.succeeded':
payment_intent = event['data']['object']
# Process the payment - update database, send receipt, etc.

return 'Success', 200
```
