Get whatsapi up and running on my server

General information for the website: Get whatsapi up and running on my server
Description of requirements/features: Hello,

I am looking to get whatsapi working on my server.
I am using godaddy PHP hosting.

Requrirements:
Whatsapi installed on server, with ability to log in to whatsapp and send/receive messages.
Possibly more work if this goes well.

Right now I have cpanel php 5.4 hosting on godaddy

Here are the details:
1. this is the API: https://github.com/mgp25/Chat-API
2. these are my hosting: cpanel hosting with php, php version 5.4

the specific requirements - i need you to install all the PHP packages required to use whatsapi, to set up whatsapi, and to provide the following functionality in PHP
1. use whatsapi to get username/password from whatsapp
2. use PHP to send a whatsapp message using username/password from #1
3. provide a listener in PHP to accept incoming messages using the username/password from #1

Should be a relatively easy project for someone who's done this before.
Specific technologies required: Linux, Godaddy, Whatsapi, PHP
