API

An Application Programming Interface (API) is a set of rules and protocols that allows different software applications to communicate with each other. APIs define the methods by which one software system can interact with another, enabling developers to access services or data provided by external applications, platforms, or devices.

APIs are essential for integrating different systems and building applications that leverage external functionalities. They specify the requests that can be made, the data formats that are accepted, and the actions that can be performed, providing a standardized way for applications to interact and exchange information.

There are various types of APIs, including web APIs that operate over the internet using protocols like HTTP, library APIs that provide pre-written functions for developers to use, and hardware APIs that enable software to communicate with physical devices. APIs play a crucial role in enabling interoperability and automation in software development.

Developers can explore and utilize APIs through documentation provided by service providers, allowing them to integrate external services into their applications, enhance functionality, and create seamless user experiences.
