get the e-mail address from signed-in google maps - javascript

I am trying to add a custom control (which is basically a button-link to another inner site) in a google-map for an specific list of gmail accounts. I have a django server. So, I think I can handle this if I were able to get the gmail address from the google map. Is there a way to do this without using oAuth2.0?
This is what I have in my header
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true&key=AIzaSyDCzPs4j72hd2GdajAWPyQunQVlsQcqg5o"></script>

There is no way Google will allow you to access your users information without OAuth 2.0, even if they are using Google maps from your website and signed in to their Google account. Since you have the API key for (And you have not mentioned for which API it is, I am assuming it is a G+ api key for OAuth2.0). You can follow the following steps in this link to retrieve basic user info such as email id once they have signed into your website using Google account. Refer to this link to get the user info. Specifically for Google API's client Library for Python, Please follow this link.
Hope this would help!!

Google Picker API for Google Workspace users only

Hi, I want the users of our organization only to use google picker to select files from their google drive.
I followed this example to set up API key and oAuth client in the google developer console.
Here is the summary of what I did:
Enabled Google Picker API in Google API Console
Created API Key
Created OAuth client
Using Official Example google picker is working but it allows all Gmail users as well, I want to allow only those emails which belong to my domain.
I could not found anything related to this in official docs so I have the following questions:
Is it possible?
Is it possible to bypass the consent screen using service account impersonation(User Access Token generated on the server via impersonation)?
This is a high level explanation, but the idea is the following:
Using a server side script, you will generate a token for a user using a service account and impersonation.
On the client side, you will have to call that script on the server side and have the server return the token.
When initializing the picker, you will set the token to what you received from the server using the PickerBuilder.setOAuthToken() method.
That way you not only bypass the consent screen, but also make sure the drive picker presents the drive files of the user you authenticated with the service account.
If you are looking for a low level explanation, edit your question and post your architecture along with your code.

get google authentication token using username and password

I have been looking for an open google api to get google authentication token by using a user's google username and password. I have came across google-auth node package. And according to it, I first need to log in to create a project in google developer console and then use the key to access the information.
But I want to know whether there is any open api where I can directly pass the username and password, without creating any project in google developer console. And get the authentication token as part of response.
This is my first project using google apis, so if it sounds naive please let me know the right way of authenticating a google account user using a node project.
Sorry, I can't provide any code, as I am stuck at understanding the initial part itself, about how to authenticate different users.
Thanks in advance
You can't use google or any social login, without first creating a project and using it's api key.
That is just how oAuth is designed.

I want to let user create Folder on Google Drive without any further signing

My purpose is to provide service on my server based on Google Drive platform. The most importantly user don't need to sign in or have google account to access this service.
As developer I want to authorize my web site URL and the Google Drive that will be mine.
I went through various solution but don't get actual one.
You may want to look at this documentation about service accounts which enables your web application to interact with google servers. The docs says:
A service account's credentials include a generated email address that is unique and at least one public/private key pair. If domain-wide delegation is enabled, then a client ID is also part of the service account's credentials.

Write to a Google spreadsheet from JavaScript using the Public API access (no OAuth)

I'd like to allow a user to visit one of my sites, enter some information into a field, and then save that information into a Google Spreadsheet via JavaScript.
I don't want the user to login via Google or have to do any special authentication.
It's Ok if the spreadsheet needs to be open to public; the data's not sensitive.
I don't want to use a Google Form, I want to have full control over the client-side UI.
I've been reading through the Google developer docs, but they only make mention to an OAuth login solution. The Google Developer Console allows you to create a "Public API access key", but does not explain how it's used.
All of the examples are for the scenario where the user is using your app to access his own files. In your case, you want the app to access your own file. This isn't easy. The only ways I can see are :-
Use a server app (appengine works well) to do the access
Very carefully set up permissions and store a refresh token in your app.
Option 2 could be your worst security nightmare if you don't do it carefully, and even then may be an infringement of Google T's and C's since it's akin to distributing your password.
Once you figure out the auth, you'll need to check out the spreadsheet API (https://developers.google.com/google-apps/spreadsheets/), as this is the API that allows you to update an existing spreadsheet. The Drive API can only upload an entire new spreadsheet.

Accessing Google Analytics API data from javascript without authentication

I wish to access Google Analytics data through their API using Javascript.
Basically I want to display on a website a list of the most visited pages for the past week/month. I can only use javascript for this.
I found this example on the official site http://code.google.com/p/google-api-javascript-client/wiki/Samples#Google_Analytics_API
Is there any way of accessing Google Analytics data without authentication? Do I need to somehow load a username/password in? To be clear, I want a website (that has Google Analytics tracking) to load analytics data from its own account.
I thought there might be a way to make certain data public, then query that somehow... Or perhaps create a limited user to access it. I can find no examples of either.
You can't access GA withouth authentication for rather the same reason you cannot access you bank account without authentication (because that would allow everybody else to access your account without authentication which might cause some inconvenience).
Google provides a complete example for GA access via Javascript: https://developers.google.com/analytics/solutions/articles/hello-analytics-api. However I don't think that's what you want (I think for that you need to be logged in to Google to actually retrieve data).
You could however use Google Apps Script to pull data into a Google Spreadsheet and embed that into your page (at least I think that should be safe).
Updated: Google has since released the Google Analytics superProxy which allows to share Analytics data with the public safely.
