It is! You can do that by creating a REST Message record and setting up the authentication. Once you set everything up ServiceNow will generate the code you need to put in the business rule automatically.

Thanks Brad for your time, below is my Client script which is working

var settings = {

    "crossDomain": true,

    "url": "https://xyz.com/helloworld",

    "type": "POST",

    "headers": {

        "Content-Type": "application/json"

    },

    "data": "{\r\n   \"operation\": \"echo\",\r\n   \"payload\": {\r\n       \"somekey1\": \"somevalue1\",\r\n       \"somekey2\": \"somevalue2\"\r\n   }\r\n}"

  };

  $j.ajax(settings).done(function (response) {

  alert(response);

    console.log(response);

  });

but when i try to use it by creating a REST message it does not return any thing, here is the code i am using in the BR

try {

  var r = new sn_ws.RESTMessageV2('TD - Test', 'post');

  var response = r.execute();

  var responseBody = response.getBody();

  var httpStatus = response.getStatusCode();

  gs.addInfoMessage("responseBody: "+responseBody);

  gs.addInfoMessage("httpStatus: "+httpStatus);

  }

  catch(ex) {

  var message = ex.getMessage();

  gs.addErrorMessage("error:"+message);

  }
