Systempay form generator for Laravel

Features

• Fast and easy form generation for Systempay (by Banque Populaire)
• Support multiple site id for multiple stores within the same project
• Support sha1 and hmac-sha-256
• Blade extension for more flexibility

Installation

1. Install the package

composer require sebastienheyd/laravel-systempay

2. Publish the config file

php artisan vendor:publish --provider="Sebastienheyd\Systempay\SystempayServiceProvider"

Configuration

After publishing edit the default configuration file : config/systempay.php

return [
    'default' => [
        'site_id' => 'YOUR_SITE_ID',
        'key'     => env('SYSTEMPAY_SITE_KEY', 'YOUR_KEY'),
        'env'     => env('SYSTEMPAY_ENV', 'PRODUCTION'),
    ]
];

You need to set YOUR_SITE_ID and YOUR_KEY with your own values. This two values are given by Systempay.

Hashing algorithms

By default, the package will use hmac-sha-256 to generate the signature. To use sha1 you need to set algo to sha1 in the configuration :

return [
    'default' => [
        // ...
        'algo'    => 'sha1'
    ]
];

Specific parameters

These parameters are set by default :

name	default value	note
currency	978	List of currency codes
payment_config	SINGLE	SINGLE or MULTIPLE
trans_date	[current datetime]	Generated automaticaly
page_action	PAYMENT
action_mode	INTERACTIVE
version	V2
signature	[generated]	Generated automaticaly

Also see Systempay documentation

NB : you don't have to add the vads_ prefix to parameters, the prefix will be automaticaly added. But you can also set the parameters with the vads_ prefix, it will be automaticaly removed.

There is also possible to set some specific parameters to a configuration by setting params values.

Example :

return [
    'default' => [
        // ...
        'params'  => [
            'currency' => '826'
        ]
    ]
];

In this case, default configuration will use the currency code 826.

Additional configuration

You can add as many configuration as you need by adding a new key to the configuration file.

For example :

return [
    'default' => [
       // ...
    ],
    'store_uk' => [
        'site_id' => '123456',
        'key'     => env('SYSTEMPAY_UK_SITE_KEY', '12345678'),
        'env'     => env('SYSTEMPAY_UK_ENV', 'PRODUCTION'),
        'algo'    => 'sha256'        
    ]
];

To use another configuration, call the config method, for example :

$systemPay = Systempay::config('store_uk')->set([
    'amount' => 12.34,
    'trans_id' => 123456
]);

Usage

In your controller :

<?php namespace App\Http\Controllers;

use Systempay; // Facade

class PaymentController extends Controller
{
    public function payment()
    {
        $systemPay = Systempay::set([
            'amount' => 12.34,
            'trans_id' => 123456
        ]);
        
        return view('payment', compact('systemPay'));
    }
}

In your view

{!! $systemPay->render('<button type="submit" class="btn">Payment</button') !!}

Or with the Blade extension :

@systempay
    <button class="btn btn-lg btn-success">Payment</button>
@endsystempay

NB : With the Blade extension, if your variable name passed to the view is not $systemPay you need to set it like this :

@systempay('paymentData')

In this example it will use $paymentData instead of $systemPay
