Following documentation described here, I have account linking set up with implicit grants and find that it works well when testing with the browser / actions console, and also with the Google Home app for Android. Unfortunately on the iphone version of the app, user auth hangs most of the time. Feedback from actions on google support is that the problem is that google sign in flow is implemented in separate browser tab (window). On iphone you can't open 2 windows in SfariViewController, thus they are re-writing address of the first page and can’t finish sign in flow. This is known issue and they are not planning to change this. The solution is to implement sign in flow all in one browser window. I'm unclear how to do this and am looking for someone to share code behind the authorization URL you set up that works consistently on iphone. Below is the core of what I am using:

#dana Have you tried adding meta tag?
<meta name="google-signin-ux_mode" content="redirect">
With help from Google support & engineering, this is now resolved:
As noted above, I had to include this meta tag: <meta name="google-signin-ux_mode" content="redirect">
I needed to have https://my-auth-endpoint.com/ in my project's authorized redirect URI. It is not enough to have it only in Authorized javascript origins. The other key thing is to include the trailing slash, I hadn't originally and it will not work without it.
Below is the simple code foundation you can use to get a working version of an authorization endpoint for actions on google account linking:

I'm using the GAPI v4 endpoint to access google sheets, I've used the example from the Google quickstart and get a 404 error of Requested entity was not found. Why would this be happening, it shouldn't be happening since I've used their example, my code:

I've tried several approaches to get this to work, neither of which work. The quickstart seems to be wrong: https://developers.google.com/sheets/api/quickstart/js
I have this code (see end of question) and all I have to do is put in my access token, the thing is I've downloaded the p12 file and whenever I try to open it, I just get some Microsoft certificate program that doesn't tell me the stuff I need, how do I go about getting inside this p12 file to get the access token that its asking for?
Thanks.

Don't try and use a service account with the embed API. Use normal oauth 2 as shown in the documentation Embeded API Getting started
gapi.analytics.ready(function() {
// Step 3: Authorize the user.
var CLIENT_ID = 'Insert your client ID here';
gapi.analytics.auth.authorize({
container: 'auth-button',
clientid: CLIENT_ID,
});
// Step 4: Create the view selector.
var viewSelector = new gapi.analytics.ViewSelector({
container: 'view-selector'
});
If you must use a service account I suggest you drop the embedded API and use a scripting language like PHP directly with the reporting API.
I went exactly by the instructions for integrating google sign-in:
https://developers.google.com/identity/sign-in/web/sign-in#specify_your_apps_client_id
sign-in works, but sign-out gives a javascript error in the line:
var auth2 = gapi.auth2.getAuthInstance();
The error is:
gapi.auth2 undefined
I include the google platform library as instructed:
<script type='text/javascript' src='https://apis.google.com/js/platform.js' async defer></script>
Why does it not work?
Are signIn and signOut used on the same page?
Div g-signin2 loads and inits gapi.auth2 so it should work as long as those are on the same page.
In case signOut is on separate page, you should manually load and init gapi.auth2 library.
Full example (you have to replace YOUR_CLIENT_ID with your actual client_id):
<html>
<head>
<meta name="google-signin-client_id" content="YOUR_CLIENT_ID">
</head>
<body>
<script>
function signOut() {
var auth2 = gapi.auth2.getAuthInstance();
auth2.signOut().then(function () {
console.log('User signed out.');
});
}
function onLoad() {
gapi.load('auth2', function() {
gapi.auth2.init();
});
}
</script>
Sign out

I already have the token and can access my token whose scopes are till fusiontable.
http://www.udayan2k12.com/token.html
<script type="text/javascript">
(function() {
var GOOGLE_AUTH_URL = "https://accounts.google.com/o/oauth2/auth";
var GOOGLE_CLIENT_ID = "365219651081-7onk7h52kas6cs5m17t1api72ur5tcrh.apps.googleusercontent.com";
var PLUS_ME_SCOPE = "https://www.googleapis.com/auth/fusiontables";
var button = document.createElement("button");
button.innerText = "Authenticate with Google";
button.onclick = function() {
var req = {
"authUrl" : GOOGLE_AUTH_URL,
"clientId" : GOOGLE_CLIENT_ID,
"scopes" : [ PLUS_ME_SCOPE ],
};
oauth2.login(req, function(token) {
alert("Got an OAuth token:\n" + token + "\n"
+ "Token expires in " + oauth2.expiresIn(req) + " ms\n");
document.getElementById('token').innerHTML = token;
}, function(error) {
alert("Error:\n" + error);
});
};
document.body.appendChild(button);
var clearTokens = document.createElement("button");
clearTokens.innerText = "Clear all tokens";
clearTokens.onclick = oauth2.clearAllTokens;
document.body.appendChild(clearTokens);
})();
</script>
But the problem is that i am unable to use that token to update the fusion table.
I want to update it specifically by using JavaScript.
can some one provide me the code to use this token to update fusiontable using the fusion table sql
You should use the JavaScript Google API client, then it is very easy to make authenticated requests to a Google API (see their "Samples" page):
gapi.client.setApiKey('YOUR API KEY');
var query = "INSERT INTO tableId (id, name) VALUES (1, 'test')";
gapi.client.load('fusiontables', 'v1', function(){
gapi.client.fusiontables.query.sql({sql:query}).execute(function(response){console.log(response);});
});
I know most of you are suffering for google auth and inserting and updating fusion table.
I am providing the entire code how to use the gauth lib to insert in a simple manner

I have implemented plupload using a ColdFusion backend script (available at https://gist.github.com/1116037).
The url attribute in the uploading page is url : '../upload.cfc?method=upload',
This simply calls a function within the cfc script. It works fine. This script also creates a variable called 'response' to hold information uploaded files.
The problem I am having is accessing the information held in the 'response' variable.
I would like to display that information in a table after the all the files have been uploaded to the server.
I am using the queue_widget for my needs’ think that an event (onComplete) needs to be triggered to call a function to process the information in variable, but I don't know how to do this.
I need to access the information held in the 'response' variable, preferably in ColdFusion code. Has anyone managed to get plupload working with ColdFusion yet?
Any help, guidance or coding would be appreciated.
Here is the full code I have used:
This is the main page - queue_widget.cfm

You can try the above example here: [url] www.turn2cash.co.uk/plupload/examples/jquery/queue_widget.cfm [/url]
As mentioned above, the script works well with uploading (in this case) upto 6 images as determined by the mnum variable. What I need help with is with how to access the uploaded files (with page refresh) and be able to manipulate them.
I have setup an example (using cffileupload) of what I am after here [url] www turn2cash.co.uk/a/index.cfm [/url]
Although this works fine, it requires a page refresh, which is what I am trying to avoid.
Please provide any help you can.
Added 7 september 2012
I have tried both methods suggested by Miguel but did not achieve any positive outcomes. They actually caused the UI not to sow at all. However I found this and tried it:
preinit: attachCallbacks,
UploadComplete: function(up, file, response) {
if ($("#result").length > 0){
$("#results").prepend(info.response);
} else {
$("#flash_uploader").after("<div id='results'>"+info.response+"</div>");
}
},
flash_swf_url : '../../js/plupload.flash.swf'
});
});
// Where should we go after upload
function attachCallbacks(Uploader){
Uploader.bind('FileUploaded', function(Up, File, Response){
alert('Response from server: ' + Response.response);
});
};
</script>
I now get an alert displaying:
Response from server: {"saved":true,"result":"home.png","id":"0","size":"5988","type":"image"}
This at least prooves that the cfc script is working and the 'response' varialable is being returned. I still have no idea how to make use of this information as I have no knowledge of jquery, ajax or javascript. Please help if you can.
The link that I posted before has the example code. Sorry to post this as an answer but since I have no rep I cannot comment.
I think part of your confusion is in the request processing. You have this line of code at the bottom of your example.
<cfif IsDefined('response')><cfdump var="#response#"></cfif>
That will never fire because the coldfusion page is processed before you make the javascript ajax call to the server for the file upload. You will need to handle the response in javascript.
Are you seeing this alert from the attachCallbacks function?
alert('Response from server: ' + response.file); // for testing only
