```

## Quick Start

```python
from sapliyio_fintech import FintechClient

client = FintechClient(api_key="sk_test_...")

# Create a payment
payment = client.payments.create(
    amount=2000,  # $20.00
    currency="USD",
    source_id="src_123",
    description="Order #1234"
)

print(f"Payment created: {payment.id}")
```

## Configuration

```python
# Custom base URL (for self-hosted)
client = FintechClient(
    api_key="sk_test_...",
    base_url="https://api.yourdomain.com"
)

# Custom timeout
client = FintechClient(
    api_key="sk_test_...",
    timeout=30  # seconds
)
```

## API Reference

)

# Get payment details

# Refund a payment
payment = client.payments.refund("pay_123", amount=500)  # partial refund
```

    currency="USD"
)

# Get wallet balance
wallet = client.wallets.get("wal_123")

# Credit (add funds)
wallet = client.wallets.credit(
    wallet_id="wal_123",
    amount=1000,
    description="Deposit"
)

    wallet_id="wal_123",
    amount=500,

# Cancel subscription
client.billing.cancel_subscription("sub_123")
```

## Webhook Handling

### Flask Example

```python
from flask import Flask, request
from sapliyio_fintech import FintechClient

app = Flask(__name__)
client = FintechClient(api_key="sk_test_...")

@app.route("/webhooks", methods=["POST"])
def webhook():
    payload = request.data
    signature = request.headers.get("X-Sapliy-Signature")
    secret = "whsec_..."

    try:
        event = client.webhooks.construct_event(payload, signature, secret)
    except ValueError:
        return "Invalid signature", 400

    if event.type == "payment.succeeded":
        payment = event.data.object
        # Handle successful payment
    elif event.type == "payment.failed":
        # Handle failed payment
        pass

    return {"received": True}
```

### Django Example

```python
from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from sapliyio_fintech import FintechClient

client = FintechClient(api_key="sk_test_...")

@csrf_exempt
def webhook_view(request):
    payload = request.body
    signature = request.headers.get("X-Sapliy-Signature")
    secret = "whsec_..."

    try:
        event = client.webhooks.construct_event(payload, signature, secret)
    except ValueError:
        return JsonResponse({"error": "Invalid signature"}, status=400)

    # Handle event
    return JsonResponse({"received": True})
```

## Async Support

```python
import asyncio
from sapliyio_fintech import AsyncFintechClient

async def main():
    client = AsyncFintechClient(api_key="sk_test_...")

    payment = await client.payments.create(
        amount=2000,
        currency="USD",
        source_id="src_123",
        description="Async payment"
    )

    print(f"Payment: {payment.id}")

asyncio.run(main())
```

## Error Handling

```python
from sapliyio_fintech.exceptions import FintechError, PaymentError

try:
    payment = client.payments.get("invalid_id")
except PaymentError as e:
    print(f"Payment error: {e.message}")
except FintechError as e:
    print(f"API error ({e.status_code}): {e.message}")
```
