==== Application programming interface (APIs) ====
[[API|Application Programming Interfaces]] are sets of rules and protocols that allow different software applications to communicate with each other. APIs define the methods and data formats that applications can use to request and exchange information.

* [[REST]]ful APIs and [[GraphQL]] are common approaches for defining and interacting with web services.

===== Types of APIs =====
* '''[[Web API]]s:''' These are APIs that are accessible over the internet using standard web protocols such as HTTP.  RESTful APIs are a common type of web API.
* '''Library APIs:''' These APIs provide pre-built functions and procedures that developers can use within their code.
* '''Operating System APIs:''' These APIs allow applications to interact with the underlying [[operating system]], accessing features like file systems, hardware, and system services.
