## **Installation**

You can install the SDK from PyPI Test or PyPI, or by cloning this repository.:

Install the SDK from the PyPI Test repository (unstable, only for test purpose):
```bash
pip install -i https://test.pypi.org/simple/ netopia-sdk
```

Install the SDK from the PyPI repository (recommended):
```bash
pip install netopia-sdk
```

Alternatively, clone this repository and install the dependencies:
```bash
git clone https://github.com/netopiapayments/python-sdk
pip install -r requirements.txt
```

You can also add the SDK to your project by copying the netopia_sdk folder to your project directory.

## **Getting Started**

### **Initialization**

```python
from netopia_sdk.config import Config
from netopia_sdk.client import PaymentClient
from netopia_sdk.payment import PaymentService

config = Config(
    api_key="your-api-key",
    pos_signature="your-pos-signature",
    is_live=False,  # True = production, False = sandbox
    notify_url="https://yourdomain.com/ipn",
    redirect_url="https://yourdomain.com/redirect",
    public_key_str="-----BEGIN PUBLIC KEY-----....-----END PUBLIC KEY-----",
    pos_signature_set=["your-pos-signature"],
)

client = PaymentClient(config)
payment_service = PaymentService(client)
```

---

### **Configuration**

The `Config` class contains the following fields:

| Field               | Type     | Required | Description                                         |

## **API Reference**

### **PaymentService Methods**

#### **StartPayment**

Initiates a payment transaction.

```python
from netopia_sdk.requests.models import (
    StartPaymentRequest, ConfigData, PaymentData, PaymentOptions, Instrument,
    OrderData, BillingData, ProductsData,
)

start_payment_request = StartPaymentRequest(
    config=ConfigData(
        emailTemplate="default",
        emailSubject="Order Confirmation",
        cancelUrl="https://yourdomain.com/cancel",
        notifyUrl=config.notify_url,
        redirectUrl=config.redirect_url,
        language="ro",
    ),
    payment=PaymentData(
        options=PaymentOptions(installments=1, bonus=0),
        instrument=Instrument(
            type="card",
            account="4111111111111111",
            expMonth=12,
            expYear=2025,
            secretCode="123",
        ),
    ),
    order=OrderData(
        orderID="R12345",
        amount=100.0,
        currency="RON",
        description="Test Order",
        billing=BillingData(
            email="customer@example.com",
            phone="1234567890",
            firstName="John",
            lastName="Doe",
            city="Bucharest",
            country=642,
        ),
        products=[
            ProductsData(name="Product1", code="P001", category="Category1", price=100.0, vat=0),
        ],
    ),
)

response = payment_service.start_payment(start_payment_request)
print("Start Payment Response:", response)
```

### Note: If the instrument is set to None, NETOPIA will handle the payment processing. 
### if the instrument is set with card details, it is mandatory for the site to implement the PCI DSS (Payment Card Industry Data Security Standard).

---

#### **GetStatus**

Retrieves the status of an order.

```python
response = payment_service.get_status(ntpID="ntpID-123456", orderID="orderID-12345")
print("Order Status Response:", response)
```

---

#### **VerifyAuth**

Handles 3D Secure verification for transactions.

```python
response = payment_service.verify_auth(
    authenticationToken="authToken123",
    ntpID="ntpID-123456",
    formData={"paRes": "paResData"},
)
print("VerifyAuth Response:", response)
```

---

### **IPN Verification**

Validates the authenticity and integrity of IPNs.

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

app = Flask(__name__)

@app.route("/ipn", methods=["POST"])
def ipn_handler():
    try:
        result = payment_service.verify_ipn(request.data)
        return jsonify({"message": "IPN verified", "data": result}), 200
    except Exception as e:
        return jsonify({"error": str(e)}), 400
```

---

## **Error Handling**

The SDK provides structured error handling with pre-defined error classes. Common errors include:

| Error Name                | Description                                              |
|---------------------------|----------------------------------------------------------|
| `MissingAPIKeyError`      | API Key is not provided.                                 |
| `InvalidPublicKeyError`   | The provided public key is invalid.                      |
| `InvalidIssuerError`      | JWT token issuer (`iss`) is not "NETOPIA Payments".      |
| `PayloadHashMismatchError`| Hash of the payload does not match `sub` in the JWT.     |
| `InvalidTokenError`       | The JWT token is invalid.                                |

### Example:

```python
try:
    response = payment_service.get_status(ntpID="ntpID-123456", orderID="orderID-12345")
except MissingAPIKeyError:
    print("API Key is missing!")
except Exception as e:
    print("An error occurred:", str(e))
```
