What is an API?

  • Share this:

An API (Application Programming Interface) is a set of rules and protocols that defines how two software systems can communicate with each other. It specifies the types of requests that can be made, the format of the request and response data, and the rules for handling errors and exceptions.

APIs are used to expose certain functionality of a software system to other developers so that they can build applications or integrations on top of it. For example, a social media platform might provide an API that allows developers to create applications that can post updates, read user data, or interact with other users.

APIs are usually implemented over HTTP, which is a protocol for sending and receiving data over the internet. This means that APIs can be accessed using standard HTTP methods such as `GET`, `POST`, `PUT`, and `DELETE`.

APIs are an essential part of modern software development, as they allow developers to build flexible and scalable applications by leveraging the functionality of other systems. They are widely used in web development, mobile development, and other areas of software engineering.
