What does API stand for?
API stands for Application Programming Interface. It is a set of protocols, tools, and definitions used for building software applications. APIs specify how software components should interact with each other.
In simpler terms, an API acts as an intermediary between different software systems, allowing them to communicate with each other and exchange data. It defines the rules and formats that must be followed when requesting services from a particular application or operating system.
APIs enable developers to access features from other systems without needing to understand their internal workings, acting like a bridge between services—for instance, letting a weather app pull real-time data from a remote server. Unlike user interfaces designed for humans, APIs facilitate machine-to-machine interactions securely and efficiently.
Common types:
- Web APIs (e.g., RESTful APIs using HTTP/JSON): Widely used for internet services like payment gateways or social media logins.
- Library/OS APIs: Built into programming languages or operating systems for tasks like file handling.
