What Are APIs? A Beginner’s Guide to Application Programming Interfaces
APIs, short for Application Programming Interfaces, act as a bridge between two systems, allowing them to communicate without exposing internal details.
For example, when you log into a website using Google, the site is using Google’s OAuth API to authenticate you securely. APIs make apps more powerful by allowing developers to use external data and services without rebuilding everything from scratch.
Types of APIs include:
- REST APIs – lightweight and widely used in web development.
- GraphQL APIs – flexible queries with reduced over-fetching.
- SOAP APIs – older but still used in enterprise systems.
- WebSocket APIs – real-time communication for chats & live updates.
In today’s tech world, APIs are everywhere—from weather apps and e-commerce payments to AI-powered chatbots.
