I have an HTML page with a button on it. When I click on that button, I need to call a REST Web Service API. I tried searching online everywhere. No clue whatsoever. Can someone give me a lead/Headstart on this? Very much appreciated.

I'm surprised nobody has mentioned the new Fetch API, supported by all browsers except IE11 at the time of writing. It simplifies the XMLHttpRequest syntax you see in many of the other examples.
The API includes a lot more, but start with the
fetch() method. It takes two arguments:
Simple GET:

Here is another Javascript REST API Call with authentication using json:

I think add if (this.readyState 4 && this.status 200) to wait is better:

Before we try to put anything on the front end of the website, let's open a connection the API. We'll do so using XMLHttpRequest objects, which is a way to open files and make an HTTP request.
We'll create a request variable and assign a new XMLHttpRequest object to it. Then we'll open a new connection with the open() method - in the arguments we'll specify the type of request as GET as well as the URL of the API endpoint. The request completes and we can access the data inside the onload function. When we're done, we'll send the request.
// Create a request variable and assign a new XMLHttpRequest object to it. var request = new XMLHttpRequest()

Usual way is to go with PHP and ajax. But for your requirement, below will work fine.

APIs (application programming interfaces) enable software applications to communicate with other pieces of software consistently. Either internally to connect to a component of the application or externally to connect to a service.
Windows 10 bluetooth passcode. REST stands for REpresentational State Transfer and is used to access and manipulate data using several stateless operations. These operations are integral to the HTTP protocol and represent an essential CRUD functionality (Create, Read, Update, Delete).
A web service is a collection of open protocols and standards used for exchanging data between applications or systems. Software applications written in various programming languages and running on various platforms can use web services to exchange data over computer networks like the Internet in a manner similar to inter-process communication on a single computer. This interoperability (e.g., communication between Java and Python, or Windows and Linux applications) is due to the use of open standards.
Web services based on REST Architecture are known as RESTful web services. These webservices uses HTTP methods to implement the concept of REST architecture. A RESTful web service usually defines a URI, Uniform Resource Identifier a service, which provides resource representation such as JSON and set of HTTP Methods.
#Node.js
Node.js is a JavaScript runtime environment that runs server-side. Within that environment, we can use JavaScript to build our software, our REST APIs, and invoke external services through their APIs. This fact is especially convenient for developers who are crossing over from front-end development as they should already be familiar with JavaScript, making the transition more natural. It also has the bonus of unifying all of the codebase under a single programming language.
The HTTP operations available are:
