How to use API?

Hi,
I have never used API. Does API be used in VSTA or other developing tool? Is there any step by step manual about using API?

You find the api in the RobotStudio application pressing Alt+F1 or “RobotStudio API help” in the help menu.

I personally use the API as a lookup when I don’t know the name of a function, or to search for functions.
