What You Need to Know About APIs

APIs are widely used for websites and apps. They have become an essential part of how communication is facilitated between applications. Because APIs are an important component of both automation and applications, they can be used to make things quicker, productive, and more flexible. APIs also enhance personalization, adaptability, integration, and efficiency. Being able to build an API is an excellent skill for a developer to have. If you're looking for a bootcamp curriculum that includes either building or using APIs, check out our comprehensive list below.

What is an API?

An application programming interface (API) is the part of a server that receives requests and sends responses. It connects applications, data, and devices so they can "talk" to each other. Some of the programming languages commonly used to build APIs include Python, Ruby, JavaScript, and Java, but most languages will work.

APIs can be either internal or external. An internal API can be used within a company to share data across platforms. An external API lets companies outside an organization use its services to build apps. A good example of this is embedding Google Maps into a web page or app so users can get directions or travel times. This helps reduce the time or cost it would take to create a map feature in a website; developers don't have to reinvent the wheel to add a feature or function that someone else has already perfected.

Why are APIs important?

Being able to work with APIs is important because they have become a fundamental part of web development. They are used for multiple purposes, including:

  • Controlling access to hardware and software functions
  • Security
  • Parking complex objects on a web page
  • Programming graphic user interface (GUI)

Developers can also benefit from knowing how to design and build an API. Businesses use APIs to extend the reach of their company and may look for a developer who can define the interactions of a particular product and then build an API that allows it to be easily integrated into other platforms.

Why use APIs?

The primary purpose of using an API is to allow applications to communicate and to make it easier to pull and send data. Not only is this beneficial within a company, but for systems in different organizations to communicate more effectively, which in turn can also help streamline the user experience.

Learn about APIs at a coding bootcamp

In a web development or coding bootcamp, APIs are a part of a larger curriculum, whether learning to use them in an application or learning to build one. You can also find shorter courses through online platforms like Udacity, Udemy, and freeCodeCamp. If you're ready to begin your search for programs that teach using or building APIs, start with the bootcamps listed below.
