APIs are the glue of modern software systems. Here’s how they work.
An Application Programming Interface (API) allows different software systems to communicate. APIs define rules for data exchange, enabling developers to integrate features from other services without building them from scratch.
For example, a weather app might use an API to fetch real-time weather data from an external provider. REST and GraphQL are two common types of APIs. Understanding APIs is crucial for modern development, as they are used in web apps, mobile apps, and cloud platforms.
