##General payment flow

Though there are multiple ways to pay an order, most payment gateways expect you to follow the following flow in your checkout process:

###1. The customer is redirected to the payment provider After the customer has gone through the checkout process and is ready to pay, the customer must be redirected to site of the payment provider.

The redirection is accomplished by submitting a form with some hidden fields. The form must post to the site of the payment provider. The hidden fields minimally specify the amount that must be paid,etc

###2. The customer pays on the site of the payment provider The customer arrived on the site of the payment provider and gets to choose a payment method. All steps necessary to pay the order are taken care of by the payment provider.

###3. Handle different Event We will post an event to the webhook URL set for your transaction's domain. If it was a live transaction, we will post to your live webhook url and vice-versa.

use Zenithcoder\Paypal\Paypal;

  public function redirectToPaypal(Request $request)
    {  
        $this->processCheckout();
        return  $this->PaypalClient()->getAuthPaymentUrl()->redirectNow();
    }

    public function handlePaypalWebhook()
    {
        $paymentDetails =  $this->PaypalClient()->getPaymentData();

        dd($paymentDetails);
        $event_types = $paymentDetails['event_types'];

          switch ($event_types)
            {
                case "PAYMENT.SALE.COMPLETED":
                    $this->completedPayment();
                    break;
                case "BILLING.SUBSCRIPTION.PAYMENT.FAILED":
                    // Handle payment failed
                    break;
                    // Handle other webhooks
                case "BILLING.SUBSCRIPTION.CANCELLED":
                        // Handle subscription cancelled
                    break;
                case "BILLING.SUBSCRIPTION.SUSPENDED":
                        // Handle subscription suspended
                    break;
                        // Handle other webhooks
                default:
                    break;
            }
    }

    public function PaypalClient(){
        return new Paypal();
    }

    public function completedPayment()
    {
        //update payment status
    }

    public function processCheckout()
    {
        try{
            $user = Auth::user();
            $subscription = Subscription::create([
                'user_id' => Auth::user()->id,
                'total'=> request()->query('amount')
            ]);


            $cartItems = json_decode( request()->query('meta'),true);
            foreach($cartItems as $cartItem)
            {
                $subscription->transactions()->create([
                    'qty' => $cartItem->qty,
                    'total' => $cartItem->qty*$cartItem->price
                ]);
            }
        } catch(\Exception $e) {

            return $e->getMessage();
        }
    }

Route::post('/pay', [
    'uses' => 'PaymentController@redirectToPaypal',
    'as' => 'pay'
]);

Route::get('/paypal/webhook', 'PaymentController@handlePaypalWebhook');

A sample form will look like so:

<form method="POST" action="{{ route('pay') }}" accept-charset="UTF-8" class="form-horizontal" role="form">
        <div class="row" style="margin-bottom:40px;">
          <div class="col-md-8 col-md-offset-2">
            <p>
                <div>
                   Robotsea
                    $350
                </div>
            </p>
            <input type="hidden" name="email" value="awonusiolajide@yahoo.com">  
           <input type="hidden" name="orderID" value="345">
            <input type="hidden" name="amount" value="800"> 
            <input type="hidden" name="quantity" value="3">
            <input type="hidden" name="currency_code" value="USD">
            <input type="hidden" name="metadata" value="{{ json_encode($array = ['key_name' => 'value',]) }}" > {{-- For other necessary things you want to add to your payload. it is optional though --}}
            
            {{ csrf_field() }} {{-- works only when using laravel 5.1, 5.2 --}}

             <input type="hidden" name="_token" value="{{ csrf_token() }}"> {{-- employ this in place of csrf_field only in laravel 5.0 --}}


            <p>
              <button class="btn btn-success btn-lg btn-block" type="submit" value="Pay Now!">
              <i class="fa fa-plus-circle fa-lg"></i> Pay Now!
              </button>
            </p>
          </div>
        </div>
</form>
