## Error Handling

The SDK raises specific exceptions that you can catch and handle:

```python
from notchpay.exceptions import (
    NotchPayError,
    ValidationError,
    AuthenticationError,
    APIError
)

try:
    payment = notchpay.payments.create(data)
except ValidationError as e:
    # Handle validation errors
    errors = e.errors
    for field, messages in errors.items():
        print(f"{field}: {', '.join(messages)}")
except AuthenticationError as e:
    # Handle authentication errors
    print(f"Authentication error: {str(e)}")
except APIError as e:
    # Handle API errors
    print(f"API error: {str(e)}")
    print(f"Error code: {e.code}")
except NotchPayError as e:
    # Handle other Notch Pay errors
    print(f"Notch Pay error: {str(e)}")
```

## Webhook Verification

Verify webhook signatures to ensure requests are from Notch Pay:

```python
from notchpay import NotchPay

# In your webhook handler
payload = request.body.decode('utf-8')
signature = request.headers.get('X-Notchpay-Signature', '')

if NotchPay.verify_webhook_signature(payload, signature, WEBHOOK_SECRET):
    # Process the webhook
    event = json.loads(payload)
else:
    # Invalid signature
    return Response(status=401)
```
