@PostMapping Annotation tells Spring for which URL to call this Endpoint.
But Endpoint will be called only for HTTP POST Requests.
You can combine it with other Annotations of this type.
For instance if you also use @GetMapping on the same Endpoint, it will get called for both HTTP GET and POST Requests.
