Laravel-Chargily-ePay

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

​
Features

  • Integrating E-Payment 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.

​
Installation

​
Step 1 - Require the package

composer require thehocinesaad/laravel-chargily-epay

​
Step 2: Publish migrations

php artisan vendor:publish —provider=“TheHocineSaad\LaravelChargilyEPay\LaravelChargilyEPayServiceProvider” —tag=“migrations”

​
Step 3: Run migrations

php artisan migrate

​
Step 4: Edit .env file

This package requires these keys:
  • CHARGILY_EPAY_KEY: You can get it from Chargily Pay’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.

​
Step 5: Epayable trait

Add the Epayable trait to your User model: 
use  TheHocineSaad\LaravelChargilyEPay\Traits\Epayable;

class User extends Authenticatable
{
    use Epayable
}

​
Step 6 (optional): Publishing

​
Config File:

php artisan vendor:publish —provider=“JohnDoe\BlogPackage\BlogPackageServiceProvider” —tag=“config”

​
Models

php artisan vendor:publish —provider=“TheHocineSaad\LaravelChargilyEPay\LaravelChargilyEPayServiceProvider” —tag=“models”

​
Using the package

​
Creating an Epay Invoice

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' => 'hello@email.com', // 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 Make() also creates an invoice in your database using the info from the provided $configurations array, so if you added columns to the migration file of the invoices table that comes with the package, you have to add the corresponding values as a second array, example: 
    $checkout_url = Epay_Invoice::make($configurations, ['product_id' => 1]);
As you saw in the example above, we added the value of product_id, that’s because you may be added product_id field in the migration file.

​
Creating an Epay Invoice for a 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. Just like the Make() function, you can add a second array to pass any added columns to the invoices table.

​
Payment Webhook

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 Pay: 
{
   "invoice":{
      "id":100000,
      "client":"Test Client",
      "client_email":"testclient@mail.com",
      "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"
   }
}

​
Testing your Webhook

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. Test Chargily Pay
