🔹What is an API?
An API (Application programming interface) is simply the set of rules guiding how a client browser communicates with a web server to exchange data.
Three parties to note are:
- Browser (Client)
- Server (Back-end)
- A network (the Internet)

When we talk about APIs, we talk about requests and responses. A client makes a request to a server for data (HTML page or json data) over a network (The internet) and the server responds with the data.
The data transmitted to and fro are stored in something called Headers.

REST API: This lets you put and pull data from a database.
Four actions in REST APIs includes:
GET: This method retrieves data from a database
POST: This method inserts data into a database
PUT: This method updates an already existing data.
DELETE: This method deletes data

The browser and server, both possess APIs for initiating and maintaining communication with each other. For the browser, we have the built-in fetch API.
This snippet displays how a browser makes an Xhr request with it:
N/B: The parameter passed to fetch must be url to the data

For the server, which can be typically set up with any server side framework, such as Express.js in JavaScript, this how the typical API looks like:
IN SUMMARY
The web browser (client) makes a request and a web server responds with data, or an error message with status codes.
The data is transmitted in two popular forms, JSON and XML.
JSON is the most widely used. So, to be able to transmit data, you must parse it to JSON

I have a cleansheet on all the API request/response properties and methods, middlewares and handler functions used by the Express API:
