I&#39;m trying to set a web service that needs the user&#39;s Google Latitude info, so I&#39;m using Google OAuth to get the user authorization stuff.

However, when trying to set the redirection URI in the Google APIs Console for a web application client ID I get a message error if I try to set it to &#39;http://PUBLIC_IP/&#39;.

I need to test it with non local users (thus localhost can&#39;t be used), so I would like to know if having a web domain is mandatory in order to use Google&#39;s OAuth. If not, how can I solve this issue?

Can a public IP address be used as Google OAuth redirect URI?

What exactly does the word &quot;offline&quot; mean with regard to the offline access granted by an OAuth server?

Does it mean that the resource server will return data about the user even when the user is logged out of the third-party application or when the user is logged out of the OAuth resource server such as Facebook or Google or Twitter?

What does &quot;offline&quot; access in OAuth mean?

I try to implement google oauth, following the [Google OAuth2ForDevices](https://developers.google.com/accounts/docs/OAuth2ForDevices). 

My App is registered on Google Cloud Console, as native App. When I try to follow the OAuth2ForDevices using Google Chromes - Advanced Rest Client Application, I get the json response with the user_code and verfication_url. Opening the verfication_url and enterering the user_code, leads to the follwoing Error: 

&gt; invalid_client: no support email
&gt; Error 400

I tried this with 2 registred Apps on Google Cloud Console. Both leading to the same error. 

**Anys hints, how to solve this? Do I have to register a `support email` somewhere in google cloud services?**

I am trying to authorise a user for Google calendar API inside an IOS app.
I am using the OAuth2 feature of Google to authenticate users. Authorisation page opens with a 403 error with the description:

&gt; This user-agent is not permitted to make OAuth authorisation request to Google as it is classified as an embedded user-agent (also known as a web-view). Per our policy, only browsers are permitted to make authorisation requests to Google. We offer several libraries and samples for native apps to perform authorisation request in browser.

I followed the same procedure which is mentioned in this link: https://developers.google.com/google-apps/calendar/quickstart/ios

Rather than seeing my code, it&#39;s better to look at this link:   https://developers.google.com/google-apps/calendar/quickstart/ios
because I copy-pasted the same thing in my application.

below are my clientId and keyChainItemName:

    static NSString *const kKeychainItemName = @&quot;Google Calendar API&quot;;
    static NSString *const kClientID = @&quot;954370342601-sgl8k0jrbqdeagea9v6vfu3tspte96ci.apps.googleusercontent.com&quot;;

I am just getting started working with Google API and OAuth2. When the client authorizes my app I am given a &quot;refresh token&quot; and a short lived &quot;access token&quot;. Now every time the access token expires, I can POST my refresh token to Google and they will give me a new access token.

My question is what is the purpose of the access token expiring? Why can&#39;t there just be a long lasting access token instead of the refresh token?

Also, does the refresh token expire?

See [Using OAuth 2.0 to Access Google APIs](https://developers.google.com/identity/protocols/OAuth2) for more info on Google OAuth2 workflow.

Why do access tokens expire?

**How can I verify a Google authentication access token?**

**I need to somehow query Google and ask: Is [given access token] valid for the [example@example.com] Google account?**

## Short version

It&#39;s clear how an access token supplied through the [Google Authentication Api :: OAuth Authentication for Web Applications][1] can be used to then request data from a range of Google services. It is not clear how to check if a given access token is valid for a given Google account. I&#39;d like to know how.

## Long version
I&#39;m developing an API that uses token-based authentication. A token will be returned upon provision of a valid username+password or upon provision of a third-party token from any one of &lt;i&gt;N&lt;/i&gt; verifiable services.

One of the third-party services will be Google, allowing a user to authenticate against my service using their Google account. This will later be extended to include Yahoo accounts, trusted OpenID providers and so on.

**Schematic example of Google-based access:**

![alt text][2]

The &#39;API&#39; entity is under my full control. The &#39;public interface&#39; entity is any web- or desktop-based app. Some public interfaces are under my control, others will not be and others still I may never even know about.

Therefore I cannot trust the token supplied to the API in step 3. This will be supplied along with the corresponding Google account email address.

I need to somehow query Google and ask: *Is this access token valid for example@example.com*?

In this case, example@example.com is the Google account unique identifier - the email address someone uses to log in to their Google account. This cannot be assumed to be a Gmail address - someone can have a Google account without having a Gmail account.

The Google documentation clearly states how, with an access token, data can be retrieved from a number of Google services. Nothing seems to state how you can check if a given access token is valid in the first place.

**Update**
The token is valid for N Google services. I can&#39;t try a token against a Google service as means of verifying it as I won&#39;t know which subset of all Google&#39;s services a given user actually uses.

Furthermore, I&#39;ll never be using the Google authentication access token to access any Google services, merely as a means of verifying a supposed Google user actually is who they say they are. If there is another way of doing this I&#39;m happy to try.

I recently came across this app [Purchase Apps](https://play.google.com/store/apps/details?id=com.azefsw.purchasedapps), which is somehow able to retrieve apps I&#39;ve paid for in google play after I signed in using my google account. 

I&#39;m trying to find out how it is being done as I want to build a similar app, but for the free apps which were downloaded. 

However, I can&#39;t find which OAuth API Scope was used for retrieving that information, even after going through [the entire list of APIs](https://developers.google.com/identity/protocols/googlescopes).

EDIT:
I&#39;m putting a new bounty on this question, as suggested by a similar question I&#39;ve asked about [**here**][2], and because here and there I don&#39;t see a real answer about how to do it, and what can be done with it.

I&#39;d like to refine the questions into multiple pieces:

1. What is the API that can be used to get information of purchased apps? Where can I read about it? Please show a full, working example of how to do it.

2. Can it do more ? Maybe perform search? Maybe show free apps that were installed? Maybe the time they were installed and uninstalled? And the categories of those apps?

3. Are there any special requirements for using this API ?

----
EDIT: I&#39;m putting a max bounty on this, because no matter how much I&#39;ve read and tried, I still failed to make a POC that can query the apps from the Play Store that the user has ever downloaded (name, package name, date installed and/or removed, icon URL, price...), including both paid and free apps.

If anyone finds a working sample, show how it&#39;s done, and also show how you&#39;ve found about it (documentation or anything that has led you to the solution). I can&#39;t find it anywhere, and the current solutions here are too vague for me to start from.

How to get list of downloaded apps (paid/free) by a user from Google Play?

I am working on Google API like chat, contacts and so on...
I am stuck on `developer_key` as mentioned in gdata doc.

You can get this at https://code.google.com/apis/console:

    &#39;developer_key&#39; =&gt; &#39;&#39;

I have already:

    // OAuth2 Settings, you can get these keys at https://code.google.com/apis/console

I am trying to access [Proximity Google API][1] using [Postman chrome app][2]. I have followed tutorials on postman and google dev website but I&#39;m still getting 401 error message. 

**What am I doing?**

 - Step 1 - Enable Proximity API:

 
In order to use Proximity API, it has to be first enabled in Google Dev console. 
Using [this][3] tutorial I have enabled support for Proximity API for my project

- Step 2 - Get the credentials:

According to [this][4] tutorial, I need to get client ID and secret. This is where I am confused. Credentials-&gt;Add credentials-&gt;OAuth2.0 client ID-&gt;select Chrome App radio button (since I am using Postman)-&gt;enter last part of Postman&#39;s Chrome Web store URL [which is [fhbjgbiflinjbdggehcddcbncdddomop\]][2]-&gt;hit create button These steps will only generate a client ID, not a secret..am I doing something wrong?

From the Google Dev console, one can download an JSON file which has client id, auth URI and Token URI
[![enter image description here][5]][5]

I downloaded this but this is of little help if I am using Postman. I am guessing this JSON file is something that can be included in a JS application.

Using Postman to access OAuth 2.0 Google APIs

I can&#39;t seem to find any documentation on how to restrict the login to my web application (which uses OAuth2.0 and Google APIs) to only accept authentication requests from users with an email on a specific domain name or set of domain names. I would like to whitelist as opposed to blacklist.

Does anyone have suggestions on how to do this, documentation on the officially accepted method of doing so, or an easy, secure work around?

For the record, I do not know any info about the user until they attempt to log in through Google&#39;s OAuth authentication. All I receive back is the basic user info and email.

Restrict Login Email with Google OAuth2.0 to Specific Domain Name

I try to make a web page for youtube video upload, therefore I try to get the client id from google api console, and in the api console it shows something like this:

    Client ID: 533832195920.apps.googleusercontent.com
    Redirect URIs: http://bobyouku.ap01.aws.af.cm/testyoutube.php
    https://developers.google.com/oauthplayground


However when I try to test my account using the following URL:

https://accounts.google.com/o/oauth2/auth?client_id=533832195920.apps.googleusercontent.com&amp;redirect_uri=http%3A%2F%2Fbobyouku.ap01.aws.af.cm%2Ftestyoutube.php&amp;scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube&amp;response_type=code&amp;access_type=offline


It gives out the result of invalid_client. Even when I try it on oauth2 playground, same fail occurs

So anyone knows what&#39;s happen?

Let&#39;s say that I have a web app (&quot;mydriveapp&quot;) that needs to access Drive files in a background service. It will either own the files it is accessing, or be run in a Google Account with which the owner has shared the documents. 

I understand that my app needs a refresh token, but **I don&#39;t want to write the code to obtain that** since I&#39;ll only ever do it once.

**NB. This is NOT using a Service Account.** The app will be run under a conventional Google account. Service Account is a valid approach in some situations. However the technique of using Oauth Playground to simulate the app can save a bunch of redundant effort, and applies to any APIs for which sharing to a Service Account is unsupported.



How do I authorise an app (web or installed) without user intervention?

Is it possible to use my personal website/blog to login to sites that use *openid*, and delegating to my Google account?

OK, I searched this question on SO but no good answer. After spent some time I figured out how to do it. I&#39;m going to answer this myself as a way to share it.

Delegate OpenID to Google (NOT Google Apps)

When making an auth request to the Google API (gapi), it&#39;s returning false on the checkOrigin.

I have removed any client id&#39;s or anything that would link directly to my account and replaced it with a regex indicating what the data is for reference.

Url: ```https://accounts.google.com/o/oauth2/iframerpc?action=checkOrigin&amp;origin=https%3A%2F%2Flocal.tools&amp;client_id=(\d{21})```

My origin url is a local url, which is `https://local.tools`

Result: `{valid: false}`

I&#39;m using the example found here without deviation (except for replacing clientid with my 21 digit clientid): https://ga-dev-tools.appspot.com/embed-api/third-party-visualizations/

The items I&#39;m trying to display show up nicely on the demo site, but aren&#39;t getting past the Not valid origin for the client error on my local.tools site.

I added an application logo by mistake on the OAuth consent screen (URL: https://console.cloud.google.com/apis/credentials/consent), and now it says my consent screen requires verification by Google. 

Is there any way to remove the application logo from the consent screen?

**Edit:**
I didn&#39;t make it clear before but I wanted to remove the logo to get rid of the verification notice.

I am playing with Google&#39;s OAuth 2.0 Playground using my own personal Google account, but I cannot seem to recover my Gmail address using the playground.

The scope I am using is:

    email profile https://www.googleapis.com/auth/plus.login

But when I call the API:

    https://www.googleapis.com/oauth2/v2/userinfo

I get various information about the user such as family name, first name, gender, picture, etc. but it does not return the user&#39;s email.

How do I retrieve the user&#39;s email address? Do I have the wrong scope or am I calling the wrong API? I feel like this should be very simple but I have literally been trying to figure this out for hours and I cannot find an API and scope combination that consistently provides the user&#39;s email address.

Google OAuth API to get user&#39;s email address?

I am trying to make an upload to YouTube from my Java based web app, I spent a few days to understand what and where is the problem and I cannot get it, for now I am pulling my hair out off my head.

I registered my web app in Google Console, so I got a pair of Client ID and Secret and a possibility to download JSON type file with my config.

So here is the config:

    {
        &quot;web&quot;:{
            &quot;auth_uri&quot;:&quot;https://accounts.google.com/o/oauth2/auth&quot;,
            &quot;client_secret&quot;:&quot;***&quot;,
            &quot;token_uri&quot;:&quot;https://accounts.google.com/o/oauth2/token&quot;,
            &quot;client_email&quot;:&quot;***&quot;,
            &quot;redirect_uris&quot;:[&quot;http://localhost:8080/WEBAPP/youtube-callback.html&quot;,&quot;http://www.WEBAPP.md/youtube-callback.html&quot;],
            &quot;client_x509_cert_url&quot;:&quot;***&quot;,
            &quot;client_id&quot;:&quot;***&quot;,
            &quot;auth_provider_x509_cert_url&quot;:&quot;https://www.googleapis.com/oauth2/v1/certs&quot;,
            &quot;javascript_origins&quot;:[&quot;http://www.WEBAPP.md/&quot;]
        }
    }

How is possible that I am getting the default URL from Google?

`The redirect URI in the request: http://localhost:8080/Callback did not match a registered redirect URI`

It always gives me the default `http://localhost:8080/Callback` URL instead of mine.

And IDE console shows me that:

`Please open the following address in your browser:
  https://accounts.google.com/o/oauth2/auth?client_id=***&amp;redirect_uri=http://localhost:8080/Callback&amp;response_type=code&amp;scope=https://www.googleapis.com/auth/youtube.upload
Attempting to open that address in the default browser now...`

I am using the last version of dependencies:
*google-api-services-youtube v3-rev99-1.17.0-rc* and *google-api-services-youtubeAnalytics v1-rev35-1.17.0-rc*

Google OAUTH: The redirect URI in the request did not match a registered redirect URI

We have a standalone Java application (see [&quot;Installed application&quot;][1])  which runs periodically and uses Google API (updates some information from customer databases/ldap/...). 

To access Google APIs we store username and password in configuration file, which is a security risk and customer does not like that. So we would like to use OAuth2 long-living *access token* instead. 

&gt; **What`s default expiration time for Google OAuth2 access tokens ?**

As we will have only *access token* in application, app itself cannot refresh it when *access token* expires. 

*Personally I think that OAuth2 implementation in this case will not bring any major benefit but let`s focus on main question - default expiration times.*

On my site I would like to allow users to sign in with a google account. I plan to use openid but I would like to allow signing in with google because it has more benefits. I&#39;ve noticed in the past a few sites that have the ability to sign in with a google (gmail) account and IIRC  though they did NOT support openID (but I could be wrong).

How do I implement &#39;sign in with google&#39;?

How do I implement ‘sign in with google’ on my site?

Is there is a way I can force the **google account chooser** to appear even if the user is logged in just with one account.

I have tried by redirecting to this URL:

    https://accounts.google.com/AccountChooser?service=lso&amp;continue=[authorizeurl]

and it seems to work, but I don&#39;t know if there are any other conditions in which it might fail.

Force google account chooser

I am developing a website that is supposed to be responsive so that people can access it from their phones. The site has got some secured parts that can be logged into using Google, Facebook, ...etc (OAuth).

The server backend is developed using ASP.Net Web API 2 and the front end is mainly AngularJS with some Razor.

For the authentication part, everything is working fine in all browsers including Android but the Google authentication is not working on iPhone and it gives me this error message

    Refused to display &#39;https://accounts.google.com/o/openid2/auth
    ?openid.ns=http://specs.openid.ne…tp://axschema.org/namePerson
    /last&amp;openid.ax.required=email,name,first,last&#39;
    in a frame because it set &#39;X-Frame-Options&#39; to &#39;SAMEORIGIN&#39;.

Now as far I am concerned I do not use any iframe in my HTML files.

I googled around, but no answer got me to fix the issue.

I have a Google App with OAuth 2.0 authentication. Everything used to work fine but recently I started getting the following &quot;Request for permission&quot; screen:

![enter image description here][1]

The strange part is that I get this screen when I pass `access_type=online`. Again, this used to work until recently.

What can be the cause for this? TIA

**Edit:**

The requested scopes are:

    https://www.googleapis.com/auth/userinfo.email
    https://www.googleapis.com/auth/userinfo.profile

I have already tried:

 - with and without `access_type=online`
 - with and without `approval_prompt=auto`

**Edit #2:**

This is the python code I&#39;m using to generate the authentication URL:

    encoded_params = urllib.urlencode({
        &quot;response_type&quot; : &quot;code&quot;,
        &quot;client_id&quot; : MY_CLIENT_ID,
        &quot;scope&quot; : &quot; &quot;.join(MY_SCOPES),
        &quot;redirect_uri&quot; : MY_REDIRECT_URI,
        &quot;state&quot; : random_security_token,
        &quot;access_type&quot; : &quot;online&quot;,
        &quot;approval_prompt&quot; : &quot;auto&quot;,
        })
	
	auth_url = &quot;https://accounts.google.com/o/oauth2/auth?&quot; + encoded_params

**Update (Oct. 14):**

Even with the new scopes, I still get the consent screen. Recently I got it for a new device I was using for the authentication.
