Laravel-Chargily-ePay is a Laravel package that provides an easy interface to Chargily ePay gateway.

• Integrating ePayment never was that fast and easy.
• Creating invoices is as easy as calling a function.
• Comes with a Migration that creates epay_invoices table with a user_id foreign id.
• A trait for the User model that gives you some very useful functions like $user->charge() to create an invoice for a user, and $user->invoices() to get all user's invoices.
• It comes with a payment webhook handler out of the box, so you just have to add your logic of what happens after a user performs a payment or cancels it.
• It has a webhook tester built in, it's like a sandbox, it's a simulation of a user paying an invoice so you don't have to test your application with real money.

composer require thehocinesaad/laravel-chargily-epay

php artisan migrate

This package requires these keys:

• CHARGILY_EPAY_KEY: You can get it from Chargily Epay's dashboard.

• CHARGILY_EPAY_SECRET: same as the first one.

• CHARGILY_EPAY_BACK_URL: This is the URL where the user will be redirected after payment processing.

• CHARGILY_EPAY_WEBHOOK_URL: This is the URL of your webhook where Chargily ePay will notify you after payment processing, we will talk about it in a bit.

Important: CHARGILY_EPAY_BACK_URL and CHARGILY_EPAY_WEBHOOK_URL should be real URLs, so you can't put http://127.0.0.1:8000, use Ngrok.

Add the Epayable trait to your User model:

use  TheHocineSaad\LaravelChargilyEPay\Traits\Epayable;

class User extends Authenticatable
{
    use Epayable
}

php artisan vendor:publish --provider="TheHocineSaad\LaravelChargilyEPay\LaravelChargilyEPayServiceProvider" --tag="migrations"

php artisan vendor:publish --provider="TheHocineSaad\LaravelChargilyEPay\LaravelChargilyEPayServiceProvider" --tag="models"

To create an Invoice, you can te use the static Make() function from the Epay_Invoice model:

use TheHocineSaad\LaravelChargilyEPay\Models\Epay_Invoice;

$configurations = [
        'user_id' => 1, // (optional) This is the user ID to be added as a foreign key, it's optional, if it's not provided its value will be NULL
        'mode' => 'CIB', // Payment method must be 'CIB' or 'EDAHABIA'
        'payment' => [
         'client_name' => 'client name here', // Client name
         'client_email' => '[email protected]', // This is where client receives payment receipt after confirmation
            'amount' => 2500, // Must be = or > than 75 
            'discount' => 0, // This is discount percentage, between 0 and 99
            'description' => 'payment for product', // This is the payment description
        ]
    ];

    $checkout_url = Epay_Invoice::make($configurations);

The Make() function returns the checkout URL, where the user should be redirected to make a payment, If any error occurs, it will return to the home page, so make sure to check this before redirecting the user.

The other way (Recommended way) to create Epay Invoices is to use the charge() custom model method which is provided by the Epayable trait, this method will automatically add the name of the client, the email of the client, and the client_id foreign key:

$configurations = [
    'mode' => 'CIB',
    'payment' => [
        'amount' => 1000,
        'discount' => 0,
        'description' => 'payment for product',
    ]
];

$checkout_url = $request->user()->charge($configurations);

The charge() method calls the Make() static function at a certain point, so they act the same way, it returns the checkout URL, or the home page URL if any error occurs.

After a user complete the payment of an invoice, Chargily ePay will notify you by sending a post request to your Webhook, so you can handle the things you would like to happen after a successful or a failed payment.

So, go ahead and create a POST Route (ex: "/webhook"), by the way, this is the URL you should add to the CHARGILY_EPAY_WEBHOOK_URL key in the .env file.

Important: You have to exclude this URL from CSRF verification, to do so, add it to the except method in your applications's App\Http\Middleware\VerifyCsrfToken middleware:

protected $except = [
        'webhook'
];

Here is the code you should put in this route as a starting point:

use TheHocineSaad\LaravelChargilyEPay\Epay_Webhook;

$webhookHandler = new Epay_Webhook;

if($webhookHandler -> invoiceIsPaied) {
    // Put here the logic you want to happen if the user actually made the payment.
}else {
    // Put here the logic you want to happen if the user canceled the payment.
}

Note: You can access the ID of the Invoice by: $webhookHandler -> invoice['invoice_number']

Here is an example of the data that comes with the post request from Chargily ePay:

{
   "invoice":{
      "id":100000,
      "client":"Test Client",
      "client_email":"[email protected]",
      "invoice_number":"I-123456789",
      "status":"paid",
      "amount":5000,
      "fee":75,
      "discount":0,
      "due_amount":5075,
      "comment":"Payment for T-Shirt",
      "mode":"CIB",
      "new":1,
      "tos":1,
      "back_url":"https://www.domain.com/",
      "invoice_token":"random_token_here",
      "api_key_id":null,
      "meta_data":null,
      "due_date":"2022-04-27 00:00:00",
      "created_at":"2022-04-27 20:59:07",
      "updated_at":"2022-04-27 21:01:09"
   }
}

I added an internal feature to simulate a payment of an invoice to test your webhook without the need to use Postman, after installing this package, you will automatically have a new route /epay-webhook-tester, navigate to it, put the ID of the invoice you want to simulate its payment and click on PAY.

Important: When you run your application using the local server php artisan serve, it will work on a single thread, so making post requests to itself will give you a timeout error, on a server, this is not a problem because it will use Apache or Nginx, the solution is to start another local server on another port (ex: 8001) and use this feature from there. Example:

1. Run php artisan serve so you will have your app on http://127.0.0.1:8000.
2. In another terminal instance, run php artisan serve --port=8001 then visit http://127.0.0.1:8001/epay-webhook-tester, not http://127.0.0.1:8000/epay-webhook-tester

Note: for security purposes, this feature works only on the local environment (APP_ENV=local), and am sure it's not needed in production.

This Laravel package is built on top of this PHP package, so have a look at it to know more about what's happening under the hood.
