Laravel #1 Payment Gateway For Zaincash

This is a Laravel Package for Payment Gateway Integration. This package supports Laravel 5.5+.

Installation

The package can be installed via Composer:

$ composer require sindibad/zaincash

Configure

If you are not using Laravel 5.5 or higher than you need to add the provider and alias.(otherwise skip this part)

In your config/app.php file add these two lines.

// In your providers array.
'providers' => [
    ...
    sindibad\zaincash\provider\ZaincashServiceProvider::class,
],

// In your aliases array.
'aliases' => [
    ...
    'ZainCash' => Zaincash\Payment\facades\ZainCash::class,
],

then run php artisan vendor:publish to publish config/payment.php file in your config directory as well as zaincash/callback.blade.php file in views directory.

In the config file you can set to use initial configs for all your payments. But you can also change some of these values like eloquent_storage,callback_url,lang,eloquent_storage at runtime.

Then fill the credentials for zaincashGateway.php file

    "eloquent_storage" => true, // Once enabled, package will create transaction_zaincash table(through zaincash:migrate command) and fill it's values when new transaction is submitted
    "callback_url" => "default", // default, <your website domain>/[your custom segment] for callback response
    "merchant_id" => "",
    "token" => '', //Secret key for jwt encode
    "msisdn" => "",
    "lang" => "en", //ar,en
    "production" => false,//Once set to true production url's will be used otherwise test url's are consumed
    ...
]

How to use

Invoice

your Invoice holds your payment details, so initially we'll talk about Invoice class.It is mainly used for transactioninit purpose;

Working with invoices

before doing anything you need to use Invoice class to create an invoice, Also note that if you're planning to use EloquentStorage use the following artisan command:

php artisan zaincash:migrate

In your code, use it like the below:

// At the top of the file.
use sindibad\zaincash\facades\ZainCash;
...

// Create new invoice.
$invoice = new Invoice;

// Set invoice amount.
$invoice->amount(1000);

// Set orderId if available, so you can get the value back on callback
$invoice->setOrderId($request->orderid);
// Set additional description or project type
$invoice->setServiceType("mydescription");
// As mentioned this can be set either in config file or directly in Invoice accessor 
// !Note that once you set it here this will be priority and not the config file values
$invoice->setLang("en");
// Callback url for callback response you can also set it to `default` for testing etc.
$invoice->setCallbackUrl("http://localhost:8000/customcallback");
// As mentioned before enabling EloquentStorage will create transaction_zaincash table inside your main db with transaction records
$invoice->setEnableElequentStorage(true);
// This parameter is set for main zaincash view files. it will set back button text
$invoice->setBackBtnText("back");
// Redirect url for main views back button
$invoice->setBackBtnUrl("http://localhost:8000/");
// you could also add extra parameters to invoice and get them back in callback response 
//you need to define a key for your Extra,note that you will use this key to receive your extra in callback
$invoice->appendExtra("key" , "value");

//Finally, use pay to initialize your transaction 
$pay = $invoice->pay();
//You can access redirect url for payment within ['url'] index 
$redirect_url=$pay['url'];
//Get error messages
$invoice->getErrors();

callBackResponse

This method is used to retrieve gatewaycallback response.it gets jwt token as it's input parameter. By default, callback response input name is token but you can change it if source callback is different. if token is not set in request status will set to 'cancel'

Working with calBackResponse

$payment= ZainCash::callBackResponse();

$payment includes following parameters

• amount: transaction cash amount
• status;: success,failed,cancel,repetitious,invalid_token
• orderId: orderId of transaction
• payment: payload data
• operationId: operation id
• config: default config settings
• extras: whole extras set in Invoice
• serviceType: service type
• initDate: transaction time in timestamp format
• backButtonText: back button text
• backButtonLink: back buttonLink
• errorMessage: error messages if any
• transaction: this parameter returns when eloquent storage is set to true

you could also use getter methods for each of these parameters like below:

$payment= ZainCash::callBackResponse();
$payment->getStatus();
//when you're using getExtra method remember to pass default value as second parameter even tough it is optional
$response->getExtra("user_id" , -1);

PaymentReceivedEvent

You could also use zaincash internal Event to receive payment info. Make a new event and definePaymentReceivedEvent::class in your EventListener. In your event, use it like the below:

   public function handle($event)
    {
        $event->getPayment();
        //Logic
    }
