What you need to know about API

An API (Application Programming Interface) is a set of rules and protocols allowing different software or systems to communicate with each other. APIs define the methods and data that an application can use to interact with another, facilitating integration and interoperability. APIs can be used for various tasks, such as accessing databases, retrieving data from web services, or automating processes. They are essential in modern environments, where applications need to collaborate, for example to integrate third-party services like online payments, interactive maps, or messaging tools. APIs can be of different types: REST, SOAP, or GraphQL, each model having its own advantages in terms of structure, flexibility, and compatibility. They play a key role in the development of web, mobile, and cloud applications.
