First of all you have to be registered within system.
If you don't have registration and would like to create new organization item from scratch than you can navigate to any website from the list and pass steps mentioned there:
Then navigate to https://admin.cplugin.net → Clients and create api account for your application. Remember login and password, you will not be able to get it later.
When you get client id and secret you can pass authorization step (which explained in another section) and start working with WebAPI (JSON and SignalR endpoints).
WebAPI hosted in MS Azure cloud.
