What is API (Application Programming Interface)?
An API (Application Programming Interface) is an interface that connects different software applications to communicate with each other to exchange data.
Think of it as a translator that helps two programs work together by sharing information or functionality. For example, when you use an app to check the weather, the app uses an API to get the latest weather data from a weather service.
How Does an API Work?
APIs follow a simple process:
Request: One software (the client) sends a request to another software (the server) through the API.
Response: The server processes the request and sends back the required data or action.
Types of APIs
APIs can be categorized as;
Data or Database APIs: It connects applications and database management systems.
Operating system (local) APIs: Used to define how apps use operating system services and resources.
Remote APIs: It is Used to define how applications on different devices interact.
Web APIs: This one enables data and functionality transfer over the internet using HTTP protocol.
