A Web API & Web service are ways for two machines to communicate with each other over a network. They both allow for information to be exchanged between a client and a server.
An API or web service hosted on a machine can receive requests from other devices(such as smartphones, computers, and tablets) over a network and sends back the requested resources, which can be in various formats like XML, JSON, HTML, images, audio files, etc.
Web APIs and web services look similar but have some key differences, so we need to know them before incorporating them into our project.
