What Is an API Endpoint and How Does It Work?

If you’ve ever heard developers talk about “hitting an API endpoint” or “calling an API,” it probably sounded like tech jargon. But the concept is much simpler than it seems. Let’s break down what an API endpoint is, how it works, and even how one is created.

What Is an API?

An API (Application Programming Interface) is like a waiter in a restaurant.

• You place an order (request).

• The waiter (API) takes it to the kitchen (server).

• The kitchen prepares it (process).

• The waiter brings your food back (response).

APIs allow apps and systems to “talk” to each other in this way.

What Is an API Endpoint?

An endpoint is the specific address (URL) where you send your request.

Example: https://api.weather.com/current?city=Johannesburg

This endpoint gives you today’s weather in Johannesburg.

Different endpoints = different types of data.

How Do API Endpoints Work?

1. Request → Your app/browser sends a request to the endpoint.

2. Processing → The server checks what you asked for.

3. Response → The server sends back the data (often in JSON format).

Real-World Examples of Endpoints

• Banking apps → Show your balance.

• Uber/Bolt → Find nearby drivers.

• Spotify/Netflix → Load playlists or recommended shows.

Why Are API Endpoints Important?

• They connect apps and systems.

• They save time by reusing existing services.

• They make businesses more flexible and scalable.

An API endpoint is simply a doorway to data and actions in software. For beginners, just think: you ask, it delivers. And now you know behind the scenes, developers create APIs by defining endpoints, handling requests, and making sure everything is secure and reliable.

So next time you log into your bank app or request a ride, remember: an API is quietly making it all work.
