🚀 Quick Start

Using the Facade (Recommended)

use GeniusCode\JTExpressEg\Facades\JTExpress;

$result = JTExpress::createOrder([
    'shippingAddress' => [
        'first_name' => 'Ahmed',
        'last_name' => 'Mohamed',
        'phone' => '01234567890',
        'city' => ['name' => 'القاهرة'],
        'street' => 'Street Name'
    ],
    'orderItems' => [
        [
            'product' => ['name' => 'T-Shirt'],
            'quantity' => 2,
            'price_at_purchase' => '75.00'
        ]
    ]
]);

if ($result['success']) {
    echo "Waybill: " . $result['waybill_code'];
}

Using Dependency Injection

use GeniusCode\JTExpressEg\JTExpressService;

class ShippingController extends Controller
{
    public function __construct(
        private JTExpressService $jtExpress
    ) {}

    public function ship()
    {
        $result = $this->jtExpress->createOrder($orderData);
    }
}

📚 Usage Examples

Creating an Order

use GeniusCode\JTExpressEg\Facades\JTExpress;

$orderData = [
    'id' => 'ORDER-12345', // Your internal order ID (optional)

    // Optional: Delivery preferences
    'deliveryType' => '04', // 01=Home, 02=Pickup, 04=Delivery

    'expressType' => 'EZ',  // EZ=Standard, KY=Express
    'weight' => 1.5,        // Weight in kg
    'total' => '150.00',    // Order total

    // Required: Shipping Address
    'shippingAddress' => [

                'description' => 'Cotton T-Shirt'
            ],
            'quantity' => 2,
            'price_at_purchase' => '75.00'
        ],
        [

        ]
    ],

    // Optional: Additional details
    'remark' => 'Handle with care',
    'totalQuantity' => '3',
];

$result = JTExpress::createOrder($orderData);

if ($result['success']) {
    // Order created successfully
    $waybillCode = $result['waybill_code'];        // JTE123456789
    $trackingId = $result['tx_logistic_id'];       // ORDER-12345
    $sortingCode = $result['sorting_code'];        // SC001
    $centerName = $result['last_center_name'];     // Cairo Hub

    // Store these for tracking later
    DB::table('shipments')->insert([
        'order_id' => $orderData['id'],
        'waybill_code' => $waybillCode,
        'tracking_id' => $trackingId,
    ]);
} else {
    // Handle error
    Log::error('Order creation failed', [
        'error' => $result['error'],
        'code' => $result['code'] ?? null,
        'status' => $result['status_code']
    ]);
}

Updating an Order

$orderData = [
    'id' => 'ORDER-12345', // The ID of the order to update
    // Include any fields that need to be updated
    'weight' => 2.0,
    'remark' => 'Updated: Handle with extreme care',
    // You must include the full shipping address and order items, even if they are not changed
    'shippingAddress' => [
        'first_name' => 'Ahmed',
        'last_name' => 'Mohamed',
        'phone' => '01234567890',
        'city' => ['name' => 'القاهرة'],
        'state' => ['name' => 'القاهرة'],
        'street' => 'Street Name',
        'building' => '10',
        'floor' => '5',
        'area' => 'مدينة نصر',
    ],
    'orderItems' => [
        [
            'product' => ['name' => 'T-Shirt'],
            'quantity' => 2,
            'price_at_purchase' => '75.00'
        ]
    ],
];

$result = JTExpress::updateOrder($orderData);

if ($result['success']) {
    // Order updated successfully
} else {
    // Handle error
}

Canceling an Order

$txlogisticId = 'ORDER-12345'; // From order creation
$reason = 'Customer requested cancellation';

$result = JTExpress::cancelOrder($txlogisticId, $reason);

if ($result['success']) {
    echo "Order cancelled successfully";
} else {
    echo "Cancellation failed: " . $result['error'];
}

Tracking an Order

$billCode = 'JTE123456789'; // Waybill code from order creation

$result = JTExpress::trackOrder($billCode);

if ($result['success']) {
    foreach ($result['data']['data'][0]['traces'] ?? [] as $trace) {
        echo "{$trace['status']} - {$trace['time']}<br>";
        echo "{$trace['desc']}<br>";
    }
}

Getting Order Details

// Single order
$result = JTExpress::getOrders('ORDER-12345');

// Multiple orders
$result = JTExpress::getOrders([
    'ORDER-12345',
    'ORDER-12346',
    'ORDER-12347'
]);

if ($result['success']) {
    foreach ($result['data']['data'] as $order) {
        echo "Bill Code: {$order['billCode']}<br>";
        echo "Status: {$order['status']}<br>";
        echo "Weight: {$order['weight']} kg<br>";
    }
}

Printing Waybill

$billCode = 'JTE123456789';
$printSize = '0'; // 0=A5, 1=100x100mm, 2=100x150mm
$printCode = 0;   // 0=No barcode, 1=Include barcode

$result = JTExpress::printOrder($billCode, $printSize, $printCode);

if ($result['success']) {
    $pdfUrl = $result['data']['url'] ?? null;

    // Download or display the waybill
    if ($pdfUrl) {
        return redirect($pdfUrl);
    }
} else {
    // Handle specific errors
    if ($result['error_code'] === '121003006') {
        echo "Order not ready for printing yet";
    } else {
        echo "Print error: " . $result['error'];
    }
}

🎯 Advanced Features

Validation

The package automatically validates order data before making API calls:

// This will fail validation (missing required fields)
$result = JTExpress::createOrder([
    'id' => 'ORDER-123'
    // Missing shippingAddress and orderItems
]);

// Returns:
[
    'success' => false,
    'error' => 'Shipping address is required for order creation',
    'status_code' => 400
]

Using Individual Components

For advanced use cases, you can use formatters and validators directly:

use GeniusCode\JTExpressEg\Formatters\AddressFormatter;
use GeniusCode\JTExpressEg\Validators\OrderDataValidator;

// Format address
$formatter = new AddressFormatter();
$addressDTO = $formatter->formatReceiver($shippingData);

// Validate order
$validator = new OrderDataValidator();
try {
    $validator->validate($orderData);
} catch (InvalidOrderDataException $e) {
    echo "Validation failed: " . $e->getMessage();
}

Exception Handling

The package provides specific exception types:

use GeniusCode\JTExpressEg\Exceptions\InvalidOrderDataException;
use GeniusCode\JTExpressEg\Exceptions\ApiException;

try {
    $result = JTExpress::createOrder($orderData);
} catch (InvalidOrderDataException $e) {
    // Handle validation errors (400)
    Log::warning('Invalid order data', [
        'error' => $e->getMessage()
    ]);
} catch (ApiException $e) {
    // Handle API errors with context
    Log::error('API Error', [
        'message' => $e->getMessage(),
        'api_code' => $e->apiCode,
        'status_code' => $e->statusCode,
        'response' => $e->responseData
    ]);
} catch (\Exception $e) {
    // Handle unexpected errors
    Log::error('Unexpected error', [
        'error' => $e->getMessage()
    ]);
}

⚠️ Error Handling

Success Response

[
    'success' => true,
    'data' => [...],
    'status_code' => 200,
    // Method-specific fields
]

Error Response

[
    'success' => false,
    'error' => 'Error message',
    'code' => 'API_ERROR_CODE',
    'data' => [...],
    'status_code' => 400|500
]

Common Error Codes

Code	Meaning	Action
145003050	Illegal parameters	Check input data
121003006	Order not printable	Wait for order to be processed
400	Validation failed	Check required fields
500	Internal error	Check logs, retry

Best Practices

// Always check success status
if ($result['success']) {
    // Process success
    $waybillCode = $result['waybill_code'];
} else {
    // Log error with context
    Log::error('J&T API Error', [
        'method' => 'createOrder',
        'error' => $result['error'],
        'code' => $result['code'] ?? null,
        'order_data' => $orderData
    ]);

    // Return user-friendly message
    return response()->json([
        'message' => 'Failed to create shipment. Please try again.'
    ], 422);
}

🔒 Security

Best Practices

1. Never commit credentials: Keep API keys in .env
2. Use environment variables: Always use env() helper
3. Validate user input: Sanitize before passing to SDK
4. Monitor logs: Check for suspicious activities
5. Use HTTPS: Always in production
