When 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 ?

You have to use API to be able to get data from a server. APIs have various data. For example, if you want to get current weather you can find some weather API, send request to it and get info on actual weather at some location.

I am very grateful for you answer becouse this think is in my mind another day. Ok thats true, same with log in on the other page using facebook account I guess. But in this course we will build an app where people can add a course and review, same as for example adding post on our wall on facebook. And I do not get it I guess. Maybe I think bad about the think which we build in this course. Can you explain where is a mistake in my thinking ? Now I do not see a diference between this app and app from Building a social network and for me it is not something which is build for other (like in this example with actual wether). Where is a mistake in my thinking ?
