ByKjetil Furas Updated onMarch 26, 2026

What is an API?

An API (Application Programming Interface) allows different software systems to communicate with each other. Think of it as a waiter taking your order to the kitchen.

Common API Types

REST: The most common type, uses HTTP methods
GraphQL: Query exactly the data you need
WebSocket: Real-time bidirectional communication

Your First API Call

Most APIs use simple HTTP requests. A basic GET request retrieves data, while a POST request sends data to create something new.

Authentication

APIs typically require authentication via API keys, OAuth tokens, or JWT tokens to ensure only authorized users can access them.
