Consume Liferay add user API with my new user

Question

I just consumed Liferay's /user/add-user json web service for creating user. Created user by using the URL

"http://localhost:9090/api/secure/jsonws/user/add-user/company-id/10153/auto-password/false/password1/123/password2/123/auto-screen-name/false/screen-name/raas/email-address/raas%40adfadf.com/male/true/send-email/true".

The default liferay admin "test" user authorization provided for the URL like ;

    String userPassword = "test" + ":" + "test"; 
    String encoding = new sun.misc.BASE64Encoder().encode (userPassword.getBytes());
    httpConn.setRequestProperty ("Authorization", "Basic " + encoding); 

And now, if I want to create a user with my second admin, how can I do authorization here? Is Liferay providing user tickets? Will that URL accept tickets? or please suggest any other ways.
