Source: Does the REST API support Client ID?

Is there any documentation about using Client ID / Token with REST API to access Group and Professional Editions?
I read about how to enable and disable services in Ubuntu and it seems that there are different possibilities to manage them.

The first method I found is update-rc.d to add new services to startup, which aims on the /etc/init.d folder and its contents.

The other one I found is to edit .conf files in the /etc/init folder.

What's the recommended way to enable / disable / add services and why?

Could you please give a short bulletproof step by step example on how to add a service in Ubuntu and enable and disable it?
