Can someone please provide guidance on how to send JSON format data via POST to a server URL, receive the response in JSON format, parse it, and retrieve the data? An example would be greatly appreciated. Thank you.

When it comes to converting data into JSON at the client side:
const jsonData = JSON.stringify(data, converter);
For retrieving the actual information on the server side:
const receivedData = JSON.parse(jsonData);
And in PHP:
<?php
$jsonString = '{"name": "John", "age": 30}';
var_dump(json_decode($jsonString));
var_dump(json_decode($jsonString, true));
?>
To easily convert JSON data in most browsers, you can utilize the JSON.parse() function.
var jsonData = {"id":1234, "name":"John Doe"};
var parsedData = JSON.parse(jsonData);
console.log(parsedData.name)
If you are working with a JavaScript library like jQuery, there may be built-in functions to assist you. Check out this related question for more information.
Here is an example of how it could be implemented.
let formData = $(":input").serializeArray();
$.ajax({
url: endpoint,
data: JSON.stringify(formData),
type: "POST",
dataType: 'json',
contentType: 'application/json'
});
On the server side :
public static function createFromJson( $jsonData )
{
$parsedObject = json_decode( $jsonData );
return new self( $parsedObject->name, $parsedObject->surname );
}
