What can we do using the POST method?

The POST method is used to send data to the server for creating or updating a resource.

Main features:

• Creating a new resource: For example, sending data to create a new record in a database (user, product, article).
• Updating an existing resource: Although PUT or PATCH are often used for this, POST can also be used to modify a resource when its identifier is not passed in the URL.
• Sending form data: Sending data filled out by the user in an HTML form.
• Sending binary data: Uploading files (images, documents).
• Performing actions on the server: Initiating operations that change the server's state (e.g., sending a message, executing a command).

Data sent via the POST method is transmitted in the request body, not in the URL. This makes it more secure for transmitting confidential information and allows sending data of virtually unlimited size.
