What is an API?
API stands for Application Programming Interface and it's essentially a doorway into an application.
Using this doorway, other third-party applications can get access to all of the data and features without needing to provide any custom code or integrations whatsoever.
The process works something like this.
An API request is sent to the application. An API request is just a simple HTTP message with some parameters telling the app what information to send back. This response will be sent back usually in JSON or XML format.
The beauty of APIs is that anyone can access information and features that would otherwise be unobtainable.
For example, most of us do not have access to a worldwide network of weather stations, but, anyone can build a mobile app and use APIs to request the data from the already existing weather application.
APIs have become so widespread, you would be hard-pressed to find a popular application these days that doesn’t offer API access.
With this amount of access to APIs, the possibilities are

For those of you new to this also understand that the word "interface" just means where two things meet. Some people think interface just means user interface. It can also be used in terms of database interface, network interface, software interface, urban wilderness interface, land sea interface etc. I've been looked at strangely by people who thought it only meant graphical user interface (GUI).

The video is explaining the concept of Web APIs, specifically, not APIs themselves. An API is just the collection of classes, methods and functions exposed by a programming library or framework. Web APIs is the same concept, but brought to the Internet. It's important to know the difference.

As a gamer and one who has used addons for games, I’ve heard of APIs for almost 20 years. I be honest to say as much as I’ve heard of the thing, I knew they did a query to the server of the MMO games I played, I’ve never had any idea how they worked. Not clearly. This was a very good example with the video in clear explanation. This has also given me an idea for my job in industrial automation.

Thanks for the quick short introduction It was really so helpful
-
Great explanation. I would add: if you’re thinking about doing this as a business, we forewarned that big companies do ‘change the rules’ for their API access whenever they wish, including starting to charge large fees.

Amazing explanation! Truly valuable, I can say I learnt so much from this channel about technology than what lecturers in schools have taught.
