When exacly we should use API ?

I still do not get what exacly API is. (I saw course about it at Treehouse and few more from the internet). In last flask course ("Building a social network..") we made an app where users can make a new posts, saw this posts etc. Can somebody explain me what is a difference between that social app and app from this course. Why we use API in this course and why we do not use it in previous course ? When we want to build API and when we do not need it ?
