# Hapi

Hapi is the object used to interact with the voisus server. It allows you to get information about the server, scenarios, sessions, and users.

## Creating a Hapi object

To create a hapi object, you must require voisus package `require('voisus')` and then call the `createHapi()` method with the server IP address. Once you have a hapi object you can then begin calling its methods in the form of `hapi."method"()`. 

### createHapi(IPAddress)

* IPAddress: `String`

```javascript

__Returns__

---------------------------------------

# Hapi Object

the following methods are called with the hapi object.

example:

```javascript
var nVoisus = require('voisus');
var hapi = nVoisus.createHapi('IPAddress');
hapi."method"(args, function(err, result) {
  ...
});
