Have you ever wondered how a travel app can display ticket prices from hundreds of different airlines instantly? Or how an online store website can accept payments through various banks automatically?
The answer is API (Application Programming Interface).
An API is a “bridge” that allows two different applications to talk and exchange data with each other without needing to know how each application was built.
Simple Analogy: A Waiter in a Restaurant
Imagine you are the customer (App A) and the kitchen is the service provider (App B/Server).
- You look at the menu and order food.
- You don’t go to the kitchen to cook it yourself.
- You give your order to the Waiter (API).
- The waiter takes the order to the kitchen and then brings the food back to you.
Without a waiter, you would have to enter the kitchen and understand how their stove works—this is very complicated and risky.
Why are APIs So Important in 2025?
- Speed Up Development: Developers don’t need to build features from scratch. Want a map feature? Use the Google Maps API. Want payments? Use the Midtrans or Stripe API.
- Ecosystem Connectivity: APIs allow your website to connect with social media, marketing tools, accounting systems, and even government databases.
- Open New Business Opportunities: You can even sell your own business data or functions to other companies through your own API.
Types of Commonly Used APIs
- Public API: Available to anyone, for example, the Twitter or YouTube API.
- Private API: Used only internally to connect different parts within a single company system.
- Partner API: Shared only with specific business partners.
