import tl = require('vsts-task-lib/task');
let auth = tl.getEndpointAuthorization("SYSTEMVSSCONNECTION", false);
var token = auth.parameters["AccessToken"];

/// <reference path="typings/index.d.ts" />

var collectionUrl = "https://xxxxxx.visualstudio.com";

let creds = vm.getPersonalAccessTokenHandler(token);

var connection = new vm.WebApi(collectionUrl, creds); 

let vstsWI: wa.IWorkItemTrackingApi = connection.getWorkItemTrackingApi();

async function getWI() {
    let wiid: number = 1;
    let workitem: wi.WorkItem = await vstsWI.getWorkItem(wiid);

    console.log(workitem.url);

createWI();
