What is an API?

APIs, short for Application Programming Interfaces, are tech’s connectors. Think of them as the middlemen enabling apps to interact. They’re a set of protocols for building and integrating application software. Quick example: you use an API when you check the weather on your phone. The app sends data to a server via an API, the server retrieves the weather info, and sends it back to your app, and voilà, you’ve got the forecast.
