# Fapshi Python SDK

A Python client library for the [Fapshi Payment API](https://fapshi.com). This SDK makes it easy to integrate Fapshi payments into your Python backend applications.

## Features

- 🚀 **Automatic Environment Detection** - Automatically detects sandbox vs live environment from your API key
- 📦 **Type Hints** - Full type annotations for better IDE support
- ✅ **Input Validation** - Validates request parameters before sending
- 🎯 **Flexible Response Format** - Choose between raw dictionaries or typed models
- 🛡️ **Error Handling** - Custom exceptions for better error handling
- 🐍 **Python 3.7+** - Supports Python 3.7 and above

## Installation

```bash
pip install fapshi
```

## Quick Start

```python
from fapshi import FapshiClient

# Initialize client (automatically detects sandbox from API key)
client = FapshiClient(
    api_user="your_api_user",
    api_key="FAK_TEST_xxx"  # Sandbox key (starts with FAK_TEST_)
)

# Generate a payment link
response = client.initiate_pay(
    amount=1000,  # Amount in smallest currency unit (min 100)
    email="customer@example.com",
    redirect_url="https://yourapp.com/callback"
)

print(f"Payment link: {response['link']}")
print(f"Transaction ID: {response['transId']}")

# Check payment status
transaction = client.get_payment_status(response['transId'])
print(f"Status: {transaction['status']}")
```

## Environment Detection

The SDK automatically detects whether you're using sandbox or live environment based on your API key:

- **Sandbox**: API keys starting with `FAK_TEST_` → uses `https://sandbox.fapshi.com`
- **Live**: All other API keys → uses `https://live.fapshi.com`

You don't need to specify the environment manually!

## Usage Examples

### Initiate Payment (Payment Link)

Create a payment link where users complete payment on a Fapshi-hosted page:

```python
response = client.initiate_pay(
    amount=1000,
    email="customer@example.com",
    redirect_url="https://yourapp.com/callback",
    user_id="user123",
    external_id="order456",
    message="Payment for order #456"
)

# Access the payment link
payment_link = response['link']
```

### Direct Payment

Send a payment request directly to a user's mobile device:

```python
response = client.direct_pay(
    amount=1000,
    phone="612345678",  # Must start with 6, without country code 237
    medium="mobile money",  # or "orange money"
    name="John Doe",
    email="john@example.com"
)

trans_id = response['transId']
```

### Get Payment Status

Check the status of a payment:

```python
transaction = client.get_payment_status("trans_123456")

print(f"Status: {transaction['status']}")  # CREATED, PENDING, SUCCESSFUL, FAILED, EXPIRED
print(f"Amount: {transaction['amount']}")
```

### Expire Payment

Invalidate a payment link:

```python
response = client.expire_pay("trans_123456")
print(f"Status: {response['status']}")  # EXPIRED
```

### Get Transactions by User

Retrieve all transactions for a user:

```python
transactions = client.get_transactions_by_user("user123")
for transaction in transactions:
    print(f"{transaction['transId']}: {transaction['status']}")
```

### Search Transactions

Search transactions with filters:

```python
transactions = client.search_transactions(
    status="successful",
    medium="mobile money",
    start="2024-01-01",
    end="2024-01-31",
    limit=50,
    sort="desc"
)
```

### Get Balance

Get your service balance:

```python
balance = client.get_balance()
print(f"Balance: {balance['balance']} {balance['currency']}")
```

### Make a Payout

Send money to a user's account:

```python
# Payout to mobile money
response = client.payout(
    amount=5000,
    phone="612345678",  # Must start with 6, without country code 237
    medium="mobile money"
)

# Payout to Fapshi account (requires email)
response = client.payout(
    amount=5000,
    email="recipient@example.com",
    medium="fapshi"
)
```

## Using Data Models

You can optionally use typed data models instead of dictionaries:

```python
from fapshi import FapshiClient, Transaction, PaymentResponse

client = FapshiClient(api_user="user", api_key="FAK_TEST_xxx")

# Get typed response
response = client.initiate_pay(
    amount=1000,
    use_models=True
)
# response is now a PaymentResponse object
print(response.link)
print(response.trans_id)

# Get typed transaction
transaction = client.get_payment_status("trans_123", use_models=True)
print(transaction.status)
print(transaction.amount)
```

## Error Handling

The SDK provides custom exceptions for better error handling:

```python
from fapshi import FapshiClient, FapshiAPIError, FapshiValidationError

try:
    response = client.initiate_pay(amount=50)  # Amount too low
except FapshiValidationError as e:
    print(f"Validation error: {e.message}")

try:
    response = client.initiate_pay(amount=1000)
except FapshiAPIError as e:
    print(f"API error: {e.message}")
    print(f"Status code: {e.status_code}")
```

### Exception Types

- `FapshiException` - Base exception for all Fapshi errors
- `FapshiAPIError` - API errors (4XX/5XX responses)
- `FapshiValidationError` - Input validation errors
- `FapshiAuthenticationError` - Authentication failures
