POST Request explained.

A POST (short for "POST request") is a method used in HTTP (Hypertext Transfer Protocol) for sending data from a client (such as a web browser or an app) to a server. In a POST request, the client sends data in the request message body, typically to create or update a resource on the server.

For example, when you fill out a form on a website and click the submit button, the data you entered in the form is sent to the server using a POST request. The server then processes the data and may send a response back to the client, such as a confirmation message or a new page with updated information.

POST requests are different from GET requests, which are used to retrieve data from a server. GET requests typically don't have a message body and are used for operations that don't modify the server's state.
