I've a WHM based server and I want to create a website (Quality) with Domain name & Site Builder API. API url is [login to view URL] . I want website to function like http://ktechost.net. I want hosting packages of my choice, integrated with API of Domain Name and Website Builder from ktechost.net. Ktechost currently belongs to me. I already have a 2 checkout account, WHM Autopilot, Paypal account to be integrated with the website.
