Web APIs Tutorial

What is Web API?

Web API is the API provided by the web browser and can be used directly to fetch any kind of data of that device or any other details according to the used API. The web includes a variety of APIs that can be used to add more functions to the web. Basically web API provides many more APIs, methods, and interfaces that can be used in JavaScript to get more features in an application.

Why Web API?

There are so many reasons to use Web APIs in the first place, these are discussed below:

• Reduces efforts: As web development or development of software is increasing day by day. everyone wants a fast web application so that we can use Web APIs, as it reduces development time and effort. The third-party APIs help to load or fetch the data fast which helps developers to put less effort.
• Less maintenance: As APIs are third-party interfaces and maintained by third party also, there is no need to look after an API and we can just fetch our data by using those APIs and use it on our current web page.
• Security: APIs are used to exchange data between two separate parties so it must be secure so that other than authorized parties no one else can access that. APIs provided by third parties are already secured by organizations with many layers.

Types of Web APIs

There are many variations of web API. Each web API is different and specific in nature, and it provides features according to their properties and methods. In web applications, we can get our work done by these web APIs.

What is Browser APIs?

API stands for Application Programming Interface that is used to make connection between the server and the client. Browser APIs are the APIs that are built in the web browser and can be used by any web page. There are many APIs that can be considered as web browser APIs for e.g. Fetch API that is used to fetch the data by making HTTP request, Device APIs that is used for fetching the information of deviced or locations, Storage APIs for getting the information about the storage of given web browser, Drawing graphics API that is used for making canvas config easily, and Audio & video APIs for management or usage od audio and video on the web browser.

What is Third-party APIs?

As we have already seen all the web APIs that are accessible directly through the web browser. But there are many other APIs that are provided by other platforms or third party for e.g. google, facebook. These website provides the API and we can access them in our browser by using JavaScript. The APIs provided by other platform are called as third-party APIs. The famous example is google map API which is used by many developers so that they can track their location or other valuable features.
