Top Programming Languages for Building APIs

Have you ever been wondering what an API is? If you’ve heard the terms web API, public API, or API before but don’t know what they mean, this article is for you.

Even though there are different approaches to what API is, IT experts and software businesses often use these terms when speaking about websites, operating systems, or applications. APIs are used everywhere, and they are incredibly important for the digital business landscape. They offer many advantages and can be useful assets in a wide range of industries. Let’s see what APIs are, how they are used, and more.

What is API?

API stands for Application Programming Interface and refers to a set of specific functions that allow applications to access data and interact with microservices, operating systems, and external software components.

When a user sends a response to a system, an API delivers it and sends the system’s response back to the user. For example, if an internet shopper adds an item to the cart, an API informs the website that a prospect added an item to their cart and goes on to process the request by providing the wanted item and updating the cart.

When it comes to APIs and microservices, the main difference is that an API is a framework that allows developers to interact with web applications, while microservices use APIs to communicate with each other.

APIs allow developers to make requests using four basic methods for updating or deleting data:

  • GET – gathers information
  • PUT – updates data such as product pricing;
  • POST – creates new sets of information such as a new product category in your inventory;
  • DELETE – deletes information.
