Data Refresh by using API: Need Steps

Hi,

I read in this article about data refresh thru API

https://powerbi.microsoft.com/en-us/blog/announcing-data-refresh-apis-in-the-power-bi-service/

but I do not know how to proceed further. I do not know anything about APIs, REST APIs etc.

Can you please help me out here to proceed further. What are the steps that I need to follow to execute below URL.
