For the app I'm building I want the end user to login using gapi OAuth2 and
from there I want the app to look for a playlist on their YouTube channel
and load it.
The getAuthInstance method returns an object with a Google username. However
for my own particular username, a query to find channel id by username
returns no results. From some browsing online, this is apparently an issue
with certain YouTube accounts.
Is there any workaround for this issue?
If you have a valid OAuth 2.0 authentication/authorization (for example, obtained by using GAPI), then it's quite simple the determine the authenticated user's channel ID using the Channels.list API endpoint queried with the parameter mine=true:
mine (boolean)
This parameter can only be used in a properly authorized request. Set this parameter's value to true to instruct the API to only return channels owned by the authenticated user.
Upon invoking the endpoint, the property id of the returned Channels resource contains the channel ID of the authenticated user.
For what concerns a Javascript GAPI (i.e. Google’s Client Library for Browser-side JavaScript) implementation, the code would look like shown below (for a broader context look into this sample source file from Google: analytics_codelab.js):
var channelId;
function loadAPIClientInterfaces() {
gapi.client.load('youtube', 'v3', function() {
getUserChannel();
});
}
function getUserChannel() {
var request = gapi.client.youtube.channels.list({
part: 'id',
fields: 'items(id)',
mine: true
});
request.execute(function(response) {
if ('error' in response) {
displayMessage(response.error.message);
} else {
channelId = response.items[0].id;
}
});
}
Note that the code above (unlike that in analytics_codelab.js) uses the fields request parameter for to obtain from the Channels.list endpoint only the channel's ID info (it is always good to ask from the API only the info that is of actual use).

I'm using the Google Login iOS SDK to login, then passing GIDGoogleUser.authentication.idToken to the server, which I'm then verifying in Node JS. The verification in the code below works fine. "payload" var ends up being correct with basic information about the user.
How do I translate the idToken into credentials that I can use to git the people.get endpoint? (I want to know whether the user is using the default Google profile photo or not, and that is available from the people.get endpoint.) This does not seem to be documented anywhere.
https://developers.google.com/people/api/rest/v1/people/get
var auth = new GoogleAuth;
var client = new auth.OAuth2(GoogleUtils.clientIDs, '', '');
client.verifyIdToken(
token,
GoogleUtils.clientIDs,
// Or, if multiple clients access the backend:
//[CLIENT_ID_1, CLIENT_ID_2, CLIENT_ID_3],
function(e, login) {
if (e) {
return next(e, null);
}
var payload = login.getPayload();
return next(null, payload);
});
Thanks for your help. I can't seem to find any of this info in the documentation. Google's APIs are very poorly documented it seems.
Unfortunately, as noted, the current ID token payload does not say whether the photo is the default one (probably something we should add). If you need an access token to call Google's REST APIs (such as people.get) for more user data, then you need to obtain an OAuth auth code, and exchange it for access and refresh tokens, as documented at https://developers.google.com/identity/sign-in/ios/offline-access
I use this URL to get id_token:
https://login.microsoftonline.com/common/oauth2/authorize?
response_type=id_token%20code&
client_id=MY_CLIENT_GUID_ID_IN_HERE&
redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fopenid%2Freturn&nonce=alfaYYCTxBK8oypM&
state=6DnAi0%2FICAWaH14e
and this return result like this
http://localhost:3000/auth/openid/return?
code=AAA_code_in_here&
id_token=eyJ0eXAi_xxxx_yyyy_in_here&
state=6DnAi0%2FICAWaH14e&
session_state=xxxx_guid_xxxxx
and then i use the id_token to query Graph (use POST man)
i have see this post InvalidAuthenticationToken and CompactToken issues - Microsoft Graph using PHP Curl but make no sense.
OATH 2.0 requires multiple steps. The first request returns an OAUTH Code. The next step is converting that OATUH code into a Bearer Token. This is the step you are missing here.
I would also recommend using the v2 Endpoint which is a lot easier to work with (particularly with Graph). I wrote a v2 Endpoint Primer that walks through the process and may be helpful as well.
You can't use the token directly, there is one more step to exchange the code you get from the response url into token.
Here is my C# code (using Microsoft.IdentityModel.Clients.ActiveDirectory)
public static AuthenticationResult ExchangeCodeForToken(string InTenantName, string InUserObjId, string InRedirectUri, string InApplicationAzureClientID, string InApplicationAzureClientAppKey)
{
Check.Require(!string.IsNullOrEmpty(InTenantName), "InTenantName must be provided");
Check.Require(!string.IsNullOrEmpty(InUserObjId), "InUserObjId must be provided");
if (CanCompleteSignIn) //redirect from sign-in
{
var clientCredential = new ClientCredential(InApplicationAzureClientID, InApplicationAzureClientAppKey);
var authContext = new AuthenticationContext(Globals.GetLoginAuthority(InTenantName), (TokenCache)new ADALTokenCache(InUserObjId)); //Login Authority is https://login.microsoftonline.com/TenantName
return authContext.AcquireTokenByAuthorizationCode(VerificationCode, new Uri(InRedirectUri), clientCredential, Globals.AZURE_GRAPH_API_RESOURCE_ID); //RESOURCE_ID is "https://graph.microsoft.com/"
}
return null;
}
I had this issue today when I was playing with graph API, the problem in my case was how I was generating the token.
I used postman for generating the token wherein the Auth URL section I was adding the resource = client_id whereas it should be the graph URL. After making that change I was able to make the call via postman.
In order for the above to work, please make sure your application in Azure has delegated permissions to access the Graph API.
To receive the access token and use it for profile requests, you don't need anything from server-side, you can implement the oAuth2 just from the client side.
Use the following URL for login:
https://login.microsoftonline.com/common/oauth2/authorize?client_id=YOUR_CLIENT_ID&resource=https://graph.microsoft.com&response_type=token&redirect_uri=YOUR_REDIRECT_URI&scope=User.ReadBasic.All
After successful login, user will redirected to the page with access_token parameter. Then use the following AJAX call to fetch user info:
var token = login_window.location.href.split('access_token=').pop().split('&')[0];
$.ajax({
url: "https://graph.microsoft.com/v1.0/me",
type: "GET",
beforeSend: function(xhr){xhr.setRequestHeader('Authorization', 'Bearer '+token);},
success: function(data) {
alert('Hi '+data.displayName);
console.log(data);
}
});
Note that you may need to enable oauth2AllowImplicitFlow:true setting from your Azure Active Directory application manifest file.
Set "oauth2AllowImplicitFlow": false to "oauth2AllowImplicitFlow": true.
Lastly, ensure that your app has required permissions for Microsoft Graph which are sign in users and View users' basic profile
An updated answer to get access with new applications:
Register your app in the app registration portal.
Authorization request example:
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?client_id=6731de76-14a6-49ae-97bc-6eba6914391e&response_type=code&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F&response_mode=query&scope=offline_access%20user.read%20mail.read&state=12345
Authorization response will look like this:
https://localhost/myapp/?code=M0ab92efe-b6fd-df08-87dc-2c6500a7f84d&state=12345
Get a token
POST /{tenant}/oauth2/v2.0/token HTTP/1.1

&grant_type=authorization_code
&client_secret=JqQX2PNo9bpM0uEihUPzyrh // NOTE: Only required for web apps
Use the access token to call Microsoft Graph
GET https://graph.microsoft.com/v1.0/me
Authorization: Bearer eyJ0eXAiO ... 0X2tnSQLEANnSPHY0gKcgw

I'm trying to use Google OAuth with Sign in & Sign Up for my Web Server Application.
This is the page : https://developers.google.com/identity/sign-in/web/backend-auth that I have referenced, but I am stuck in using the Google Client API, the TokenVerifier that is mentioned below in the document. I tried to find some examples, but I couldn't find one, as I am not sure how to handle the parameters in the methods that the sample shows.
import com.google.api.client.googleapis.auth.oauth2.GoogleIdToken;
import com.google.api.client.googleapis.auth.oauth2.GoogleIdToken.Payload;
import com.google.api.client.googleapis.auth.oauth2.GoogleIdTokenVerifier;
...
GoogleIdTokenVerifier verifier = new GoogleIdTokenVerifier.Builder(transport, jsonFactory)
.setAudience(Arrays.asList(CLIENT_ID))
.build();
// (Receive idTokenString by HTTPS POST)
GoogleIdToken idToken = verifier.verify(idTokenString);
if (idToken != null) {
Payload payload = idToken.getPayload();
if (payload.getHostedDomain().equals(APPS_DOMAIN_NAME)
// If multiple clients access the backend server:
&& Arrays.asList(ANDROID_CLIENT_ID, IOS_CLIENT_ID).contains(payload.getAuthorizedParty())) {
System.out.println("User ID: " + payload.getSubject());
} else {
System.out.println("Invalid ID token.");
}
} else {
System.out.println("Invalid ID token.");
}
For example, I know what these CLIENT_ID, ANDROID_CLIENT_ID, IOS_CLIENT_ID parameters mean in the sample code(in the reference page), but the server only receives id_token, which is basically a String Text. (That was made by the google api in the client-side, the javascript)
So, I do not have these parameter values passed to the server from the client. I know that google shows another way: the tokeninfo endpoint, but they mentioned that it is for only 100user/month only. (If I translated it correctly) However, for the tokeninfo endpoint way, they return the JSON file of containing client ids, which I think that would be the values for the parameters that I mentioned before, but I do not want to use the token info endpoint method.
So, my question is, how do I get the right parameter values for the sample code that is showed in the google document page? I only receive id_token value from the client.
ANDROID_CLIENT_ID or IOS_CLIENT_ID should be hard coded (in a config file) in your server's code.
Essentially your server is getting an id_token in a request and you need to make sure if it is meant for your app or server by checking the audience in there and making sure it matches one of the values you are expecting.
I'm experimenting with Google Apps Script and Twitter, and I'd like to be able to access multiple Twitter accounts through one spreadsheet. At the moment I've attempted the approach below (a unique OAuthService name for each Twitter account), and this kind-of works but it clunky because I have to randomly authorize one account (and not more than one) each time the script is run, and the popup dialog doesn't tell me which account (i.e. id) I'm authenticating for.
Ideally, I'd like to force each user to give Twitter permission on first use, then store that token for later use - is this possible withe Google App Script?
Thanks.
function oAuth(id) {
var oauthConfig = UrlFetchApp.addOAuthService(NS_TWITTER + id);
oauthConfig.setAccessTokenUrl("https://api.twitter.com/oauth/access_token");
oauthConfig.setRequestTokenUrl("https://api.twitter.com/oauth/request_token");
oauthConfig.setAuthorizationUrl("https://api.twitter.com/oauth/authorize");
oauthConfig.setConsumerKey(CONSUMER_KEY);
oauthConfig.setConsumerSecret(CONSUMER_SECRET);
};
and then
var options =
{
"method": "GET",
"oAuthServiceName":NS_TWITTER + id,
"oAuthUseToken":"always",
};
try {
var result = UrlFetchApp.fetch(feed, options);
}
Yes, is possible.
To store the token values use userProperties (Docs here) or CacheService wich remains for 20 minutes in cache (Docs here).
Example storing token using UserProperties
UserProperties.setProperty('token', 'value');
var token = UserProperties.getProperty('token');
Example storing token using CachService
// Gets a cache that is private to the current user
var cache = CacheService.getPrivateCache();
cache.put('token', 'value');
var token = cache.get('token');
After building you cache solution you need to check if the token is valid with twitter API. If it's invalid you should require the auth again.
I'm trying to use the YouTube Data API V2.0 to pull data insights for the videos/channels of our client. I have a developer key and a token that my client generates, and successfully figured out how to retrieve that information. My problem is, when my client uses the app for YouTube token generation, we are asking for an access that means EVERYTHING and to be able to "manage" their accounts.
This is a major concern for the client and they don't want us to have this kind of complete access. Is there a way to get a token generated with only read-only permission?
Thanks very much for any help!
I have successfully used https://googleapis.com/auth/youtube.readonly as a scope; if you ask for just that scope during the initial oAuth flow (and NOT for https://googleapis.com/auth/youtube at the same time, as that is the management scope which will override the readonly scope), then you will get a 403 error whenever attempting an action that requires management permissions (inserting, uploading, updating, deleting).
The google-api clients for v3 handle this quite smoothly, if you're using them. If you have written your own oAuth flow control, just make sure you have the sole readonly scope when requesting the initial token.
EDIT IN RESPONSE TO COMMENT: To view this in action (I'll use javascript to show), you can create a simple demo using the sample code provided by the API docs. Here's the general process:
1) In the Google API console, create a 'project' and authorize the YouTube API for that project (under the Services tab). Additionally,create a client ID for web applications (under the API access tab) and add in your domain as an authorized Javascript domain.
2) On your server, create and HTML file to serve as your interface (in this sample, it is designed to let you create a new playlist and add items to it). Here's the code, straight from the docs:
<!doctype html>
<html>
<head>
<title>Playlist Updates</title>
</head>
<body>
<div id="login-container" class="pre-auth">This application requires access to your YouTube account.
Please authorize to continue.
</div>
<div id="buttons">
<button id="playlist-button" disabled onclick="createPlaylist()">Create a new Private Playlist</button>
<br>
<label>Current Playlist Id: <input id="playlist-id" value='' type="text"/></label>
<br>
<label>Video Id: <input id="video-id" value='GZG9G5txtaE' type="text"/></label><button onclick="addVideoToPlaylist()">Add to current playlist</button>
</div>
<h3>Playlist: <span id="playlist-title"></span></h3>
<p id="playlist-description"></p>
<div id="playlist-container">
<span id="status">No Videos</span>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="auth.js"></script>
<script src="playlist_updates.js"></script>
<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script>
</body>
</html>
3) In that same location, create the script "playlist_updates.js" with this code (again, straight from the docs):
// Some variables to remember state.
var playlistId, channelId;
// Once the api loads call a function to get the channel information.
function handleAPILoaded() {
enableForm();
}
// Enable a form to create a playlist.
function enableForm() {
$('#playlist-button').attr('disabled', false);
}
// Create a private playlist.
function createPlaylist() {
var request = gapi.client.youtube.playlists.insert({
part: 'snippet,status',
resource: {
snippet: {
title: 'Test Playlist',
description: 'A private playlist created with the YouTube API'
},
status: {
privacyStatus: 'private'
}
}
});
request.execute(function(response) {
var result = response.result;
if (result) {
playlistId = result.id;
$('#playlist-id').val(playlistId);
$('#playlist-title').html(result.snippet.title);
$('#playlist-description').html(result.snippet.description);
} else {
$('#status').html('Could not create playlist');
}
});
}
// Add a video id from a form to a playlist.
function addVideoToPlaylist() {
addToPlaylist($('#video-id').val());
}
// Add a video to a playlist.
function addToPlaylist(id, startPos, endPos) {
var details = {
videoId: id,
kind: 'youtube#video'
}
if (startPos != undefined) {
details['startAt'] = startPos;
}
if (endPos != undefined) {
details['endAt'] = endPos;
}
var request = gapi.client.youtube.playlistItems.insert({
part: 'snippet',
resource: {
snippet: {
playlistId: playlistId,
resourceId: details
}
}
});
request.execute(function(response) {
$('#status').html('<pre>' + JSON.stringify(response.result) + '</pre>');
});
}
Finally, create the file "auth.js" -- this is the code that actually does the oAuth2 flow:
// The client id is obtained from the Google APIs Console at https://code.google.com/apis/console
// If you run access this code from a server other than http://localhost, you need to register
// your own client id.
var OAUTH2_CLIENT_ID = '__YOUR_CLIENT_ID__';
var OAUTH2_SCOPES = [
'https://www.googleapis.com/auth/youtube'
];
// This callback is invoked by the Google APIs JS client automatically when it is loaded.
googleApiClientReady = function() {
gapi.auth.init(function() {
window.setTimeout(checkAuth, 1);
});
}
// Attempt the immediate OAuth 2 client flow as soon as the page is loaded.
// If the currently logged in Google Account has previously authorized OAUTH2_CLIENT_ID, then
// it will succeed with no user intervention. Otherwise, it will fail and the user interface
// to prompt for authorization needs to be displayed.
function checkAuth() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: true
}, handleAuthResult);
}
// Handles the result of a gapi.auth.authorize() call.
function handleAuthResult(authResult) {
if (authResult) {
// Auth was successful; hide the things related to prompting for auth and show the things
// that should be visible after auth succeeds.
$('.pre-auth').hide();
loadAPIClientInterfaces();
} else {
// Make the #login-link clickable, and attempt a non-immediate OAuth 2 client flow.
// The current function will be called when that flow is complete.
$('#login-link').click(function() {
gapi.auth.authorize({
client_id: OAUTH2_CLIENT_ID,
scope: OAUTH2_SCOPES,
immediate: false
}, handleAuthResult);
});
}
}
// Loads the client interface for the YouTube Analytics and Data APIs.
// This is required before using the Google APIs JS client; more info is available at
// http://code.google.com/p/google-api-javascript-client/wiki/GettingStarted#Loading_the_Client
function loadAPIClientInterfaces() {
gapi.client.load('youtube', 'v3', function() {
handleAPILoaded();
});
}
Note in there the OAUTH2_SCOPES constant. It's set to allow full management access, so if you then visit the html page in your browser and click on the 'authorize' link, you should see the window asking you to grant your domain access to manage your YouTube account. Do this, and then the code becomes functional ... you can add playlists and playlist items to your heart's content.
If you, however, then modify auth.js so that the OAUTH2_SCOPES looks like this:
var OAUTH2_SCOPES = [
'https://www.googleapis.com/auth/youtube.readonly'
];
and clear your cookies (to avoid inheriting the permissions you already granted ... just closing the browser and relaunching ought to be enough), then try again (visit the HTML, click the authorize link), you'll see that this time it's asking you to grant permission only to VIEW the account rather than manage it. If you grant that permission, then when you try to add a playlist through the interface you'll get an error message appearing that says you can't create the playlist.
If you're not using javascript, but instead a server-side language, as I mentioned the gapi clients are quite smooth. However, the handling of oAuth2 scope in these clients is not quite as transparent, and they're by design 'greedy' (in that, as it abstracts a service endpoint to an object, it will request the most thorough scope it needs to do any of the actions at that endpoint ... so even if you only intend to do list calls, if the service has an update action as well the client will request full management privileges). This can be modified, though, if you want to get into the client code -- or you could use it as a model for creating your own simplified client that you can granularly control in terms of scope.
That's about as thorough as I can be without knowing your underlying technologies. Hope the explanation helps!
