google-script-asana-api.js

function getAsanaUsers() {
  var options = {
   "headers" : {
     "Authorization": "Bearer <TOKEN>"
   }
  }
  var response = UrlFetchApp.fetch("https://app.asana.com/api/1.0/workspaces/<workspace-id>/users", options);

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheets = ss.getSheets();
  var sheet = ss.getSheetByName("asanaUsers"); // specific sheet name; alternatively use ss.getActiveSheet()

  var dataAll = JSON.parse(response.getContentText()); //
  var dataSet = dataAll.data; // "data" is the key containing the relevant objects
  
  var rows = [],
    data;
  
  for (i = 0; i < dataSet.length; i++) {
  data = dataSet[i];
  rows.push([data.id, data.name]); //your JSON entities here
  }

  // [row to start on], [column to start on], [number of rows], [number of entities]
  dataRange = sheet.getRange(2, 1, rows.length, 2);
  dataRange.setValues(rows);
