API Calls
API calls are requests made by a client application to a server's API (Application Programming Interface) to perform operations such as retrieving, creating, updating, or deleting data. They typically use protocols like HTTP/HTTPS with methods such as GET, POST, PUT, and DELETE, and involve sending and receiving structured data formats like JSON or XML. This concept is fundamental to web development, enabling communication between different software systems.
Developers should learn API calls to build applications that interact with external services, such as fetching weather data from a third-party API or integrating with social media platforms. It's essential for creating modern web and mobile apps that rely on backend servers, microservices architectures, or cloud-based resources, allowing for scalable and modular software design.
