Rest API Integration using Mid Server in ServiceNow

[aragarw]

Hello All,

I want to make a REST API call to third party system using mid server. The proid that runs mid server uses Kerberos authentication and I need to use the same authentication method. However, I don't know what details need to be mentioned in the code for Kerberos authentication by mid server when making the REST API call. Below is the code that I have written but as you can see there is no authentication mentioned in this code, please help me on what details do I need to add in this code for Kerberos authentication method:

var requestBody;

var responseBody;

var status;

var sm;

try{

    sm = new sn_ws.RESTMessageV2();  

    sm.setEndpoint("http://sn-qa.m.com/api-docs/#!/default/authorize ");

    sm.setHttpMethod("get");

    sm.setQueryParameter("user","abc");

    sm.setQueryParameter("symbol", "NOW");

    sm.setQueryParameter("action", "approve");

    sm.setQueryParameter("eonid","1221");

    sm.setMIDServer('mid server name');

    response = sm.executeAsync(); 

    response.waitForResponse(60);

    responseBody = response.haveError() ? response.getErrorMessage() : response.getBody();

    status = response.getStatusCode();

} catch(ex) {

    responseBody = ex.getMessage();

    status = '500';

} finally {

    requestBody = sm ? sm.getRequestBody():null;

}

gs.info("Request Body: " + requestBody);

gs.info("Response: " + responseBody);

gs.info("HTTP Status: " + status);
