Payment widget integration with token

To make the Demo PSP payment widget appear to your customers on your website, follow the steps below:

Install the widget script.

To make the widget send requests, run the following script on your website:
```
<script type="text/javascript" src="https://js.begateway.com/widget/be_gateway.js"></script>
```

Create the payment widget.

Register a function to generate the necessary parameters for the BeGateway constructor object, and to call out the createWidget method. The payment is considered as successfully completed only after you receive the automatic payment notification.

<script type="text/javascript">
    this.payment = function() {
        var params ={
            checkout_url: "https://checkout.begateway.com",
            fromWebview: true,
            checkout: {
                iframe: true,
                test: true,
                transaction_type: "payment"                                  
            },
            token: "8765a020e1bfe88780943461769f09e0f6ed576431a14a7165ccf6827adf9377", 
            closeWidget: function(status) {
              // possible values of status variable
              // successful - transaction is successful
              // failed - transaction is declined
              // pending - awaiting transaction confirmation
              // redirected - customer is redirected to external the payment method system
              // error - error in input paras/network error/etc
              // null - payment widget is closed
              console.debug('close widget callback')
            }
        };

        new BeGateway(params).createWidget();
    };
</script>

Call the created function.

Register the call of the above created function to some event, for example, to the “Pay” link click.
```
<a onclick="payment()" href="#">Pay</a>
```


checkout_url required	string `https://checkout.begateway.com`
token conditionally required	string Payment token received in request for a payment token. In this integration option, the customer can not make changes to the payment parameters.
fromWebview	boolean Set this parameter to `true` if you want the payment widget to open on payment initialization in a WebView (for example, within a web application). If this parameter is not provided, or it is set to `false`, initializing the payment will open the payment page instead.
