Ohjelmointirajapinnassa, or API (Application Programming Interface), is a set of definitions and protocols that allows different software applications to communicate with each other. It acts as an intermediary, defining the methods and data formats that applications can use to request and exchange information. APIs enable developers to access the functionality of other software or services without needing to understand their internal workings.

For example, a weather application might use a weather service's API to retrieve current weather data and forecasts for a specific location. The application makes a request to the API, specifying the desired information, and the API returns the data in a structured format, such as JSON or XML. This abstraction allows developers to build complex applications by leveraging existing functionalities and data sources.

APIs are crucial for modern software development, facilitating integration between various systems, enabling third-party developers to extend the capabilities of existing platforms, and promoting the development of microservices architectures. They are fundamental to the interconnected nature of today's digital landscape, powering everything from mobile apps and web services to enterprise systems and the Internet of Things. Understanding APIs is essential for anyone involved in software development or system integration.
