# 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:

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.parallels.com/landing/ras-client-integration-guide/v20/ras-web-client-api/json-payload.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
