So I am working with google sheets API , where I need to authorize the credentials before I can hit api for my account , for that OAuth2 client provides an auth URL which opens in browser and there I have to login in Gmail account and then accept the permissions and then it redirects to a redirect URI and in it's URL there is a code.
But I want to get all this done automatically as this will be part of my backend code , and I want it be automated without me going to browser and logging in . Can this be done using puppeteer ? or anything else ?
The only option to avoid user interaction is to use a service account with domain-wide delegation. And to use this, you need to be a Workspace domain admin, and you can only act on behalf of users in your Workspace domain.
If you are not a domain admin, there's no way to avoid the workflow you mentioned, with user interaction.

I'm developing a (so far) intra-company website that needs authentication (i.e. a limited set of users are allowed to use it). I don't want to force the users to have a new username/password pair for only this service. The company already uses company-branded Google Mail for e-mail, so every user already has a Google account: my "cunning plan" is let Google authenticate the users.
I found this great question and answer so I know (or at least have an idea) on how to verify on the server side that the web session was authenticated by Google. What I don't know: how to get that accessToken on the client side? How to detect if the user already logged in to Google, and if not, how to present the Google login form to the user?
I found the Using OAuth 2.0 to Access Google APIs documentation, but I don't quite understand this sentence: "The authorization sequence begins when your application redirects a browser to a Google URL; the URL includes query parameters that indicate the type of access being requested.". What is this URL?
I'm fairly new to web development and JavaScript, unfortunately.
"The authorization sequence begins when your application redirects a browser to a Google URL; the URL includes query parameters that indicate the type of access being requested.".
Your application will need to open a webpage which will display a consent screen to the user. This page is opened on Googles identity server not your own. You have probably seen this before.
The url is built up using the client id and redirect URI that you set up on your project in the Google developer console.
https://accounts.google.com/o/oauth2/auth?client_id={clientid}.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=https://www.googleapis.com/auth/analytics.readonly&response_type=code

Apps Script keeps asking for offline permission with Youtube's API
In Google Apps Script, access to YouTube Reporting API is Forbidden
These are very similar questions however, I am logged in as the owner. The script is in the owner's drive.
My problem
I have been trying to access YouTube Analytics Reports from the Content Owner using GAS(Google Apps Script). There are two accounts a Brand account (holds the data i.e. the video content) and a User account. They both use the same credentials(email & pwd). When authorizing as the user, I get a 403(forbidden). When authorizing as the brand, I am asked to authorize offline access again and again, stopping me from ever being able to make a request.
What I've tried...
Running from Node, using OAUTH Playground tokens, and it works. But I need to stick with GAS.
Using google-script-oauth2: to hard code credentials (similarly to the Node solution) but I couldn't set the refresh token. I got a 401(invalid credentials) - I believe the bearer token was expired
Setting up credentials for and enabling both youtube and youtube analytics APIs
scrapping old credentials and attaching a new project to GAS
removing auth in privacy settings and re-authenticating
toggling a use unsafe scripts option and repeating step 3
switching between contentOwner and channel parameters for the ids param
NOTE: I have two OAUTH2 credentials app script and the web client both are set as Web Applications.
GAS Code
function test(){
YouTubeAnalytics.Reports.query("contentOwner==id", "2017-03-01", "2017-03-31", "likes");
}
Final Thoughts
I believe there is a disconnect between the Brand and the user such that the brand is not given the same access to the OAUTH 2 token. Therefore, it never generates a refresh token. So, the request sees that I am the authorized channel owner but it can't finish the OAUTH flow.
If this is true, why, and how do I fix it? If not, what do you think could be the error?
I just realized the script is in the user account and not the brand account. Would that affect the validation?
Also on the actual channel, the user is listed as the Primary Owner.
I think the problem has to do with Apps Script's limited OAuth scopes. Open the Script Editor and navigate to Resources->Advanced Google Services and you'll see that YouTube's Reporting API is not supported. However, you can get around this by using Service Accounts. They are a pain to set up but once you get them up and running you can explicitly request the scopes required to make authorized calls on the API from GAS.
Here are a few links to get you started:
Using OAuth 2.0 for Server to Server Applications
OAuth 2.0 Scopes for Google APIs
For Using OAuth 2.0 for Server to Server Applications you'll want to scroll down to the section titled Preparing to make an authorized API call. Select the HTTP/REST tab and it should walk you thru the steps you'll need to setup a service account (you'll need to create a JWT - JSON Web Token from your Google console for use in your API calls). You'll also need to retrieve the needed OAuth scope urls for YouTube's Reporting API from the second link provided. Once you're all set up you'll be able to make requests to the API directly from Apps Script using URLFetchApp. Best of luck with your project.
One more thing. Check out Google's API Explorer listing for the YouTube Reporting API. You can get the URL endpoints (and request methods) you'll need to use in your UrlFetchApp calls by playing with the Explorer.
UPDATE 4/28/2017
Also be sure to enable the YouTube Reporting API from your Google API Console.
I have a scenario that I think should be fairly simple, yet I'm not finding a solution and wondering if someone can point me in the right direction.
The setup:
1) SharePoint online website (user must be authenticated to see page)
2) .NET MVC Web API service endpoint (user must be authenticated to get data from the service)
Both of these authenticate using the same Azure Active Directory. The Web API has been registered in Azure AD.
The problem:
I would like to put some javascript on a SharePoint Online page (not a Sharepoint Add-in, not an AngularJS SPA) that will make an AJAX call to the Web API using the logged in user's credentials without any kind of user prompt (since this is an ajax call, the user won't see the prompt anyway).
I've tried looking into the ADAL libraries, but all the JavaScript ones I can find require the use of Angular and require the user to authenticate a second time. I've found some documentation using OAuth 2.0, but (from what I can tell) require you to get the client to authorize the Sharepoint Online page to act on their behalf - which the user will not be able to consent to because it's an AJAX call and the consent page is not displayed in the browser (and it's still doing this despite having the app already approved by an administrator in Azure AD).
It seems to me the user shouldn't have to leave the SharePoint page and shouldn't have to enter their credentials a second time. I believe there should be some way that the log-in to SharePoint Online should also be able to be used as the log-in for our in-house app.
If someone could just point me in the correct direction, I would be very much appreciate it. Thanks in advance.
Normally, if we call the resource which protected by Azure AD, we need to authorize the app via OAuth 2.0.
Were you able to put a hidden iframe in the SharePoint online page? If it is possible, then we can use the Azure AD implicit flow get the token through iframe, and we can call the REST which protected by Azure AD via the token return by iframe. To enable the implicit flow, we need to download the application manifest from Azure portal and switch ‘oauth2AllowImplicitFlow’ to true.
And if you were only developing a single tenant which doesn’t require users to consent the app. Here is the HTML code request the token from a Iframe for your reference:
<iframe width="0" height="0" id="oauthHideIframe" src="https://login.microsoftonline.com/{tenantId}/oauth2/authorize?response_type=token&client_id={Client_Id}&redirect_uri={redirect_Url}&resource={your web api app url register on the protal}"> </iframe>
And to pass the token from iframe to the parent window, we can use the window.postmessage which allow the corss-orignal communication.
I understand that I can use Google Sign in button and grant access to my website only to users from my domain (using metadata tag).
My question is, once a user is logged in can I control the pages that he/she sees. For example I want some users to be admins but other users to be regular users. Each user 'type' will have access to different set of pages.
Thanks,
Shay
Google's sign-in API can only authenticate users, it can't manage authorizations. For that you'll need to either use a cloud service like Cognito (which supports Google sign-in as a federated login provider for its own temporarily-generated identity) or write your own server-side access manager that associates the sign-in token with specific permissions, and then handles the authorization of user requests.
I'm currently building a frontend client for my own Apigility API.
The API uses OAuth 2.0 Authentication which is working fine.
I want to create an AngularJS Landingpage to let the users authenticate by entering their credentials. Because the Client is created with JavaScript,
I shouldn't save the client_secret in the Client, correct?
I have read a lot of posts, but still haven't the right solution.
Is it correct to use the implicit grant type for this scenario?
This procedure is working, I'm being redirected to the authentication server,
after the client authorization and entering credentials, I get back to the client (authenticated).
But I don't want to get redirected to another authentication page.
Is it also possible to authenticate directly and secure on the angularJS frontend?
Thanks,
Simon
You should take a look at this post i made:
https://stackoverflow.com/a/42443878/2963703
It details how to do this using the Spotify API. Your page won't get redirected, instead a popup window will open in which the user authorizes themselves. Once they're authorized the window will close itself and in your main page you will have the access token you need.
