In this article, you can find APIs online courses for all levels.
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an API specification. A computer system that meets this standard is said to implement or expose an API. The term API may refer either to the specification or to the implementation.
In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to call that portion of the API. The calls that make up the API are also known as subroutines, methods, requests, or endpoints. An API specification defines these calls, meaning that it explains how to use or implement them.
One purpose of APIs is to hide the internal details of how a system works, exposing only those parts a programmer will find useful and keeping them consistent even if the internal details later change. An API may be custom-built for a particular pair of systems, or it may be a shared standard allowing interoperability among many systems.
The term API is often used to refer to web APIs, which allow communication between computers that are joined by the internet. There are also APIs for programming languages, software libraries, computer operating systems, and computer hardware. APIs originated in the 1940s, though the term did not emerge until the 1960s and 70s.
API Crash Course: What is an API, how to create it & test it
Tarek Roshdy & Nezam Academy via Udemy
In this course we will explain what an API is. API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you re using an API. What exactly is an API? Finally learn for yourself in this helpful video from MuleSoft, the API experts. When you use an application on your mobile phone, the application connects to the Internet and sends data to a server. The server then retrieves that data, interprets it, performs the necessary actions and sends it back to your phone. The application then interprets that data and presents you with the information you wanted in a readable way. This is what an API is – all of this happens via API.

Fundamentals of APIs
Andy P. via Udemy
An API is a platform that allows different pieces of software, or applications, to communicate with one another. The term is used broadly in the context of programming languages, the web, operating systems, etc. For example, Apple publicly shares a number of APIs powered by iOS its operating system for iPhones and iPads for app developers to use. These APIs allow applications like Instagram and Snapchat to use a device s camera, microphone, and much more. This course covers the essentials of APIs of modern web development, explaining what APIs are and how to use them to quickly incorporate data into your websites.

REST Assured API Automation + Framework: From Zero to Hero!
Omprakash Chavan via Udemy
REST Assured API is one of the most popular library when it comes to automating the REST APIs. Most of the today’s web applications are backed by the Micro services architecture and the REST APIs. Make no mistake, REST is gaining a lot of popularity amongst the developer community. As a QA engineer, it becomes very important to test the REST APIs as a working API is crucial for a product. With great adoption of OAuth 2.0 and Open ID Connect authentication mechanisms, it also becomes important to build an in–depth understanding of these authentication mechanisms. To speed up product delivery, the industry is gradually moving towards end to end continuous integration (CI) and continuous development/deployment process (CD). So it becomes critical that the backend API services are automated to facilitate and speed up this process.
