Get sys_id from current user using REST API Services

[markwinap]

Hi, Im using Authorization code grant flow (OAuth 2) to authenticate users and get them access to Service Now RESTful APIs. My question is, how do i get the user sys_id (similar to  var currentUser = gs.getUser(); gs.info(currentUser.getID());) using the available RESTful APIs.

My current workaround is,POST to the incident table and get the sys_id from opened_by key

If it is a scripted rest api, you can easily assign value to an attribute.

For example body.USER = gs.getUserID();
