Reddit service for Goa examples

This describes how to authenticate with Podio using Goa, as described in Oauth2 for Apps Script in a few lines of code (which you should read first for background).

The library, cGoa, is available under this project key.


Setting up

You'll need to create an App. The dashboard/developers console can be found here

Your one time setup would look something like this. 
  cGoa.GoaApp.setPackage (propertyStore , { 
    clientId: "xx",               
    scopes : ["identity"],
    service: "reddit",
    packageName: "reddit"

The example

The example includes 3 functions.
  • A doGet example for a web app.
  • An example where the token has already been setup by a one off doGet example
  • An example of consuming the token
The doGet should be published 

function doGet(e) {
  return doGetPodio (e);

and will create a consent screen like this, from which the redirect URI can be copied and added to the App dashboard.

The patterns

 * this is how  to do a webapp which needs authentication
 * @param {*} e - parameters passed to doGet
 * @return {HtmlOurput} for rendering
function doGetReddit (e) {
  // this is pattern for a WebApp.
  // passing the doGet parameters (or anything else)
  // will ensure they are preservered during the multiple oauth2 processes
  // change this to whatever store & credentials name are being used
  var goa =  cGoa.GoaApp.createGoa('reddit',PropertiesService.getScriptProperties()).execute(e);
  // it's possible that we need consent - this will cause a consent dialog
  if (goa.needsConsent()) {
    return goa.getConsent();
  // if we get here its time for your webapp to run and we should have a token, or thrown an error somewhere
  if (!goa.hasToken()) throw 'something went wrong with goa - did you check if consent was needed?';
  // This is a webapp doing whaever its supposed to do
  // getParams is used to retrieve the original parameters passed to this function
  var result = testReddit (goa.getToken(), goa.getParams() );   
  // now return it as normal
  return HtmlService.createHtmlOutput (result.getContentText())


function reddit(params) {
  // pick up the token refreshing if necessary
  var goa =  cGoa.GoaApp.createGoa('reddit', PropertiesService.getScriptProperties()).execute(params);
  if (!goa.hasToken()) {
    throw 'for a non webapp version - first publish once off to provoke a dialog - token will be refreshed automatically thereafter';
  // do a test - passing the token and any parameters that arrived to this function
  Logger.log (testReddit (goa.getToken(), goa.getParams() ));

 * this is your main processing - will be called with your access token
 * @param {string} accessToken - the accessToken
 * @param {*} params any params
function testReddit (accessToken,params) {
   var options = {
     method: "GET",
     headers: {
       authorization: "Bearer " + accessToken

   return UrlFetchApp.fetch("", options);
