PAYMENT RESULT NOTIFICATION
--------------------------------

PayTabs payment gateway provides means to notify your system with payment result once transaction processing was completed so that your system can update the transaction respective cart.

To get use of this feature do the following:


1- Defining a route (Optional)
--------------------------
Laravel PayTabs PT2 package comes with a default route for incoming IPN requests. The route URI is  _/paymentIPN_ ,  if you don't like it this URI just ignore it and define your own. Look at _routes/routes.php_ to get a clue.



2- Implementing a means to receive notification
------------------------------------------

To receive notification, do one of the following:
* While creating a pay page, passed this route as  a Callback URL to _sendURLs_ method, that URL will receive an HTTP Post request with the payment result. For more about callback check: **merchant dashboard** > **Developers** > **Transaction API**.

* Second means is to configure IPN notification from merchant dashboard. For more details about how to configure IPN request and its different formats check: **merchant dashboard** > **Developers** > **Service Types**.


3- Configuring a callback method
--------------------------------
Now, you need to configure the plugin with the class\method that will grab the payment details and perform your custom logic (updating cart in DB, notifying the customer ...etc ).

* In your website _config/paytabs.php_ file, add the following:

        'callback' => env('paytabs_ipn_callback', new namespace\your_class() ),

* In your class add new method, it must named: **updateCartByIPN**

        updateCartByIPN( $requestData){
            $cartId= $requestData->getCartId();
            $status= $requestData->getStatus();
            //your logic .. updating cart in DB, notifying the customer ...etc

            //Hold On Reject support
            // if $status = "H" this is mean the transaction is hold on reject.
            // you can't make capture for it from your system.
            // you must make the capture from paytabs dashboard side.
            // make sure to add your ipn value to paytabs dashboard from here:
             "{paytabs portal}/merchant/developers/ipnconfig".
        }
you can also get transaction reference number. To get the list of available properties check: _Paytabscom\Laravel__paytabs\IpnRequest_ class.
