What is an API (Application Programming Interface) ?
The video uses the waiter analogy to simplify how APIs act as intermediaries between users and servers. It includes real-world examples like weather updates, third-party logins (e.g., "Sign in with Google"), and online payment systems to illustrate how these "messengers" facilitate secure data exchange without requiring direct access to a system's core codes.
You'll also find insights into different types of APIs, such as Web (REST) and Internal systems, and how they enable the complex connectivity and automation essential for modern cloud-based environments.
