Kashier Payment Gateway for Laravel

A Laravel package for integrating with the Kashier payment gateway in your Laravel applications.

Overview

This package provides a simple and elegant way to integrate Kashier payment processing into your Laravel applications. It handles payment requests, callbacks, and webhooks with minimal configuration.

Features

• Easy integration with Kashier payment gateway
• Support for multiple payment methods (cards, wallets, bank installments)
• Secure payment processing with hash verification
• Webhook handling for payment notifications
• Response handling for payment callbacks
• Event-driven architecture for custom payment processing logic

Installation

You can install the package via composer:

composer require asciisd/kashier

Configuration

Publish the configuration file:

php artisan vendor:publish --provider="Asciisd\\Kashier\\Providers\\KashierServiceProvider" --tag="config"

Then, set your Kashier credentials in your .env file:

KASHIER_MID=your-merchant-id
KASHIER_API_KEY=your-api-key
KASHIER_SECRET_KEY=your-secret-key
KASHIER_MODE=test # or live
KASHIER_CURRENCY=EGP # or any other supported currency
KASHIER_CALLBACK_URL=https://your-website.com/payment-complete # optional custom redirect URL

Usage

Basic Payment Processing

use Asciisd\Kashier\Facades\Kashier;

// Generate a payment URL
$paymentUrl = Kashier::buildPaymentUrl(
    amount: 100, // Amount in the smallest currency unit (e.g., piasters for EGP)
    orderId: 'order-123', // Your unique order ID
    attributes: [
        'customerName' => 'John Doe',
        'customerEmail' => '[email protected]',
        'customerMobile' => '01234567890',
        // Additional attributes as needed
    ]
);

// Redirect the user to the payment URL
return redirect()->away($paymentUrl);

Customizing Payment Methods

use Asciisd\Kashier\Facades\Kashier;

// Allow only specific payment methods
$paymentUrl = Kashier::setAllowedMethods('card,wallet')
    ->buildPaymentUrl(100, 'order-123');

Handling Payment Responses

The package automatically handles payment responses at the /kashier/response endpoint. You can listen for the KashierResponseHandled event to process successful payments:

use Asciisd\Kashier\Events\KashierResponseHandled;
use Illuminate\Support\Facades\Event;

Event::listen(function (KashierResponseHandled $event) {
    $paymentData = $event->payload;
    
    // Process the payment data
    // $paymentData['paymentStatus'] contains the payment status
    // $paymentData['merchantOrderId'] contains your order ID
    // ...
});

Custom Redirect After Payment

By default, users are shown a receipt page after completing payment. If you prefer to redirect users to your own custom page, you can set the KASHIER_CALLBACK_URL in your .env file:

KASHIER_CALLBACK_URL=https://your-website.com/payment-complete

When this is configured, users will be redirected to your custom URL after payment processing, with all payment data included as query parameters. This allows you to create a completely custom post-payment experience.

Handling Webhooks

Kashier will send webhook notifications to the /kashier/webhook endpoint. You can listen for the KashierWebhookHandled event to process these notifications:

use Asciisd\Kashier\Events\KashierWebhookHandled;
use Illuminate\Support\Facades\Event;

Event::listen(function (KashierWebhookHandled $event) {
    $webhookData = $event->payload;
    
    // Process the webhook data
    // Update order status, send notifications, etc.
});

Retrieving Transaction Details

use Asciisd\Kashier\Facades\Kashier;

try {
    $transactionDetails = Kashier::getTransactionDetails('order-123');
    
    // Process transaction details
    // $transactionDetails['paymentStatus'] contains the payment status
    // ...
} catch (Exception $e) {
    // Handle error
}

Security

The package automatically verifies the signature of incoming webhook and response requests to ensure they are legitimate and have not been tampered with.

Events

• KashierResponseHandled: Dispatched when a payment response is received
• KashierWebhookHandled: Dispatched when a webhook notification is received
