An API, or Application Programming Interface, is a set of defined rules that enable different applications, services, or systems to communicate with each other. It allows data to be shared, processed, or retrieved from another system, enabling integration and interoperability.
Think of an API as a messenger between systems. Imagine you’re at a restaurant and you want to order food. You can’t just walk into the kitchen and start making your own food because that’s not how it works. Instead, you give your order to the waiter (the API), and they take it to the kitchen (the system) and bring back the food (the data) you requested.
There are different types of APIs, including:
1. Web APIs: Used for web applications and websites.
2. Operating system APIs: Used for desktop and mobile applications.
3. Library APIs: Used for software libraries.
APIs typically define a set of endpoints, or URLs, that can be used to interact with the system, as well as the structure of the data that is sent and received.
I hope that helps! Let me know if you have any other questions.
