# JSON Payload

The JSON payload that the RAS Secure Gateway receives as a response has the following structure (the values are for demonstration purposes only and should be substituted with your own):

```
_RASWebClientLoadApp({ 
   u: 'username', 
   q: 'password', 
   a: '#4', 
   p: 'c:\\temp\\another.txt',
   logonURL: 'https://example.com/logon',
   logoutURL: 'https://example.com/logout',
   extra: {
     redirectPrinter: true,
     redirectLinks: true,
     redirectSound: true
   }
});
```

{% hint style="info" %}
**Note:** You can also use the older function `_RASHTML5LoadApp` instead of `_RASWebClientLoadApp` for backwards compatibility.
{% endhint %}

The following table describes the available JSON parameters:
