- curl

  curl is a command-line tool used to transfer data to or from a given URL. It serves as an HTTP client that can send HTTP requests to the HTTP server and receive response messages. You can also use curl to debug APIs. For more information about curl, visit https://curl.haxx.se/.

- REST client

  Both Mozilla Firefox and Google Chrome provide a graphical browser plugin, the REST client, which you can use to send and process requests.
