Some people probably do not know the existence of API, whereas they use API all the time and they do not even know it. If you are reading this article, You must have heard people around you using the word “API” and wondered what an API actually is, how it works, and why it is important to developers, etc.  

This article will help you find the answer to those questions, let’s check it out!

What is API?

API stands for Application Programming Interface, which is a software intermediary that allows applications to communicate with one another. API is like an interpreter for two people who do not speak the same language to help them communicate easily to meet each other’s needs. For mobile or web developers, API plays a very important part in any development project, because it can simplify the process of website or application development.

What are the Example of API and How Does It Work?

When you use an application for any activity or transaction, the application connects to the internet and sends data to a server. Then, the server retrieves that data, interprets it, and performs the necessary actions and sends it back to that application. Then, the application will interprets that data and presents you with the information in a human-readable way. All of those processes happens via API.

To make it easier to understand, we have prepared the familiar and real-life examples for you. Let’s look at the following explanation.

Today, we are living in a digital era and everything is digital. We get a lot of convenience in ordering various kinds of tickets through an aggregator application, for example, flight tickets.

In the application, there are a variety of options to make the process of searching flights easier, including departure and return city and date, flight classes, amount of passengers, as well as other variables. After that, you will get the response to your request. This is where API comes into play to make those processes run smoothly.

When people use aggregator application to book the tickets, the aggregator application will interact with the airline’s API to access their database and see if any seats are available on those dates and what the costs might be. Then, API takes the airline’s response to user request and delivers it right back to the aggregator application, which then shows user the most updated, relevant information.

Therefore, API is very important for both developers and website or application’s user. By using API, developers do not need to code or build programs from scratch. With API, website or application’s users will also find it easier to do their needs, because they can immediately get the data or information without having to leave each page of the website or application.

Conclusion

From the explanation above, we can conclude that API is the most important aspect for developers, because it can simplify the process of website or application development.

To take full advantages of API and to ensure that the API perform and scale to meet enterprise requirements, developers can make use of API management solution. API management solution make it easy for developers to design, develop, implement, and monitor API — even when it needs to be integrated with legacy systems.
