API

What does it mean

API stands for Application Programming Interface. It is an interface that allows different software applications to communicate with each other. You can think of it as a mediator that allows one application or system to access the functions or data of another application. In this way, different applications can exchange information without having to be directly connected.

How Does an API Work?

An API defines how requests for services between software systems can be sent and what data or operations can be performed. This process mostly happens in the background, and the user doesn't even notice it. Imagine it like a restaurant: the customer (your application) asks the waiter (API) for food (data or function), and the waiter then brings the order from the kitchen (another system).

Types of API

There are several types of API, each with a specific role:

1. Web API – allows applications to communicate over the internet (e.g., Facebook API for accessing social data).

2. Operating API – allows different parts of a system to communicate (e.g., API for accessing files or hardware).

3. Database API – used for communicating with databases and manipulating data.

Examples of Use

Simple examples of API usage:

• When booking a flight through a website: the API retrieves information about flight availability from various airlines.
• When using Google Maps on another site: the API displays maps and locations directly on the page, without needing to visit Google Maps.

Why is API Important?

API significantly facilitates software development because it allows the integration of various functions and services without the need to create them from scratch. It also improves efficiency and supports innovation because developers can build on existing solutions and easily integrate new features.

API is an important tool for modern applications and systems. It allows them to easily collaborate and provide new, richer user experiences without the need for constant code rewriting.
