An API request is a way for one software application to communicate with another software application to access or exchange data or functionality.
To make an API request, a client application sends a request to the receiving application (referred to as server application) using a specific URL, which includes:
A request method – such as GET, POST, PUT, DELETE
Any necessary parameters or data
The server application then processes the request and sends a response back to the client application, usually in the form of structured data – in formats such as JSON or XML.
APIs are widely used
API requests can be used for a wide range of purposes, including retrieving data from a remote server, submitting data to a remote server for processing, updating data on a remote server, and triggering specific actions or events on a remote server.
API requests are widely used in web and mobile application development, as well as in the integration of various software systems.
In fact, every time you visit a website you are effectively sending a request!
