Google calendar API grantOfflineAccess() without a pop up - google-calendar-api

We have been working on an app that requires access to a users google calendar. We have been using the grantOfflineAccess() method described in google api's documentation - https://developers.google.com/identity/sign-in/web/reference#googleusergrantofflineaccessoptions
However, the problem we are facing is that this opens a pop up and we need to do this via a redirect. Does anyone have any ideas todo this without a pop up showing up?
Safari and Firefox block pop ups and this does not really work well on safari on mobile.
I was able to find a GitHub issue for this https://github.com/google/google-api-javascript-client/issues/288 but I have seen other websites do this without a pop up. You can check zendesk & frontapp.com - both of whom take offline grant for the users signing in.
Any ideas or help would be appreciated.

The only way to access a users data is to have a user grant you permission to access that data. This is done though Oauth2 a user is promoted to login to their google account then they are given a screen with the scopes of permissions that you are requesting.
There is no way around this. YOu will always have to ask a user at lease once to grant you permission to access their data if you are requesting offline access you will be given a refresh token that you can use to request a new access token and access the users data when they are not online.
As for popups they shouldn't be displaying as popups they should be opening in a new browser window.

'Token has been expired or revoked' - Google OAuth2 Refresh token gets expired in a few days

I am using Google Analytics API to fetch analytics data. I tried to authenticate it using following steps:
Created OAuth client ID in https://console.developers.google.com/ credentials section.
In consent screen I had set publishing status as testing
In OAuth 2.0 Playground I got the refresh token using above generated client id and client secret
Then I am using it to generate access token through it.
But after a few days, the refresh token expires although it is mentioned that the refresh token's validity is life long.
If your app is in testing mode then user tokens will expire in 7 days. Please find this explanations here: https://support.google.com/cloud/answer/10311615#zippy=%2Ctesting
I needed to send mails from a gmail account that I have access to, using nodemailer. It works for a couple of days before my refresh token is mysteriously revoked, even though the account belongs to me. A google search brought me here and I had been watching for a while hoping someone would help with a solution.
As you mentioned, this seems to happen with only test/unverified apps and I'm guessing google revokes tokens for such applications in your account after a few days. After much trials and errors, here is what I did.
NOTE: This is solution is only applicable to accounts you own, otherwise you must verify your app to access other people's accounts
Generate a new refresh token (existing one is most likely revoked) as described in this SO post
Go to the security tab of your google account dashboard
Under the Recent security activity section, you should see a security alert for your app.
Click on the context menu next to the notification and click DISMISS
At this point you'll be presented with a dialog of options where you indicate the level of trust you have for the app. I just went ahead and said I trusted the developer/app, obviously. And that's it! The refresh token should persist after this.
I could not find anything related anywhere else.
The other answer pointed me in the right direction but for me the option was located somewhere else: security > security checkup/security issues found > context menu next to your app > dismiss
This issue seems to be for unverified apps, Simply delete the token file from your project and rerun the project, it will create a new token.
My problem was when I've added access_token instead of refresh_token.
What I did:
Go to https://console.cloud.google.com/apis/credentials/consent and change from the testing status to published.
Delete the current token file.
Authorize the API again by signing into your gmail account. You will be sent to a warning screen. From there, you can choose to proceed.
When done you'll get a new token file
The solution is to delete your token.json file to force Google to find a new token.
I was able to get it to work WITHOUT a verified app. Perhaps the refresh() method will work once my app is verified. Not sure on that one.

Can't login using Google Auth, 403: org_internal

Can't login using Google Auth,
Error 403: org_internal
This client is restricted to users within its organization.
Go to cloud console (https://console.cloud.google.com/apis/)
APIs and services
Credentials
Oath consent screen
Ensure Application type is set to "public" and not internal.
Obviously assuming that you are creating an app that should be accessible outside your org. If this is related to testing and phones, it is possible to create testusers that are excepted from company policy rules.
The reason for this error is indeed because the Application type is set to "internal".
But setting it to public is not always the right answer...
Add "&prompt=select_account" to the authentication url. This will force the user to select the correct (organization-)account.
Without the parameter, Google tries to show the consent screen for the logged in Google-account, but as it is not an organization-account it will just display the 403 page without giving the user this choice.

I had an Internal app that I was trying to authenticate with one of our YouTube channels using an organization account, and I was getting the same error:
Authorization Error
Error 403: org_internal
This client is restricted to users within its organization.
After contacting Google Workspace Support, they asked me to Change the restriction on it from Limited to Trusted.
Steps are mentioned in this support thread: https://support.google.com/a/answer/7281227
Open the Google Admin Console.
From the sidebar menu, choose: Security → API Controls.
Click on MANAGE THIRD-PARTY APP ACCESS button.
Hover the cursor over the required app and click on Change access.
Choose the option: Trusted: Can access all Google services
And save the CHANGE.
Once you've done, take note that there will be 24 hours of propagation on it before it gradually takes effect.
Make sure, for the browser you are using, that you have logged out of "All" Google account(s). This should force the "select account" windows to display.
We have almost exactly the same problem while trying to configure WP Mail SMTP for Wordpress.
The OAuth Client's Application Type has to be "Internal" so changing it to "External" was not an option for us.
Hope this helps.
I had the same issue and in my case was because the project didn't had a support email address set it.
I fix it by adding one on the Firebase Console > Project Settings > General under the Public settings section.
This error is most likely due to the configuration of your application in Google Cloud Platform.
Setting your application to "internal" is causing this error. Try making your app "external" in the OAuth consent screen, but make sure it is in a "testing" status. Then, add yourself to the test users. This configuration will work well for an internal, lightweight application.
Once complete, try to authenticate with the channel again.
I had the same issue with a project. The error only appeared if I tried to log in to my app while already logged in with an account outside the organization (worked just fine while logged out of all accounts, or while logged in with an internal organization account). I had to change the OAuth Client's Application Type from Internal to Public in the Google Dev Console.

Maybe you have another google email to login, not the correct one.

Meteor Restivus: keep user logged in if he goes to the main website

I have a Chrome extension that communicates with my Meteor app through a REST API created with the Restivus package.
The user authenticates to the REST API and then uses authenticated tokens to make any further requests.
So far, everything works fine, as long as he stays within the extension. However, from the chrome extension, I'd like to redirect the user to his profile page on my main website. When that happens, he's no longer authenticated, and must re-sign-in to access the profile page.
I figure this is because the REST API session and the webpage session are two completely different sessions on the server (even though both the API and the webpage run from the same server). My question is, is there a way to maintain the user's logged-in state as he moves from the extension to the main website?
I figure there are a few options:
I'm using the standard meteor accounts package. Is there a way to push whatever standard cookie / data that the accounts package uses, to the user's browser, so that when he goes to the website, he'll be considered logged in?
Push a custom cookie to the user, which I then check for and log him in when he first comes to the website. However, I don't know how to push a cookie through a REST API or generate one in the Chrome extension
Use DDP to communicate with the second session and transfer the login credentials.
I don't know if these are the best options (or even how to implement them if they are...). Has anyone figured out a way to do this already? Thanks!
I would suggest you to develop your own flow of authentification using a token as an URL parameter. You should achieve a similar experience that slack provides with magic authentification links
The idea is to generate a token and add it to the Meteor.users collection for the user logged in your chrome extension.
Then, redirect your user to an url with the token as a parameter. The app checks which user is linked with this token and log him in.
You can get inspiration on what is done in the account package to handle enrollment and reset links, or in the passwordless package

Anonymous Log in with Firebase (Javascript)

I know there is a way to log in anonymously with Google Firebase, but I haven't gotten it working. The issue I am having is that my app needs to be accessible on any device without logging into any account with the app.
It needs to have full control of the app's database, both reading and writing. This app isn't really meant for public use, so I am OK with anonymous authentication. I also should not have to click a button in order for it to authenticate, it should do it automatically. I tried adding the code that Google provides, but it still wont authenticate. It does work with a Google account.
Thanks!
It was an issue related to the database rules. The default rules are set so that only authenticated users are able to read and write to the database. I set both so that anyone can read or write to the database from any device without logging in.

What type of facebook auth/token do I need for this?

I want to build a custom asp.net control to put on a webpage that will allow people to see a piece of information from my facebook account that requires auth. For the sake of simplicity let's just say I'd like it to display the last thing that I liked. I don't want the visitor to my site to have to be logged into facebook (nor would they have to be my friend on fb). I want my site to somehow store a token that I have authorized and then it will use this token for the access. I know this can be done initially, but I'm confused what happens when the token expires. Or for that matter if I log out from facebook. Is there some type of token or secret or something that I can request that can be auto-renewed again and again by my website independent of any login state that I have as an fb user? Does this require me creating an fb app and associating the token to it?
I don't have any code at this point, I'm looking for a higher level of guidance on the protocol that should be used here, from there I can hopefully figure out the code from existing samples, docs, etc. This is my first code interaction with facebook so don't assume that I know very much at this point :-)
EDIT: I've been reading everything I can about this topic and I can't seem to find a solution. In the past there was an RSS feed but that appears to be gone now. Then there was also the offline_access permission which is no longer available. This seems like such a simple task but I'm just not able to connect the dots. I have been able to get the initial user token with perms for reading "likes", that's easy. Now I can store that in my website's db and use it to make requests for that data anytime someone loads my page. But eventually the token will expire and I'm not seeing any automatic way to renew it that wouldn't potentially involve user "Larry", who happens to be browsing my website, being asked to supply MY facebook credentials. Basically it seems as though I could never log out from facebook or I'd be risking a broken feed on my website. Is the fb auth model just not set up to allow for thist? To summarize again - a user Bob wants to give his permission to acme.com to always be able to display Bob's most recent like regardless of whether Bob is logged in to fb or not. He would only want to have this stop working if he revoked authorization to the WhatDoesBobLike app which runs on acme.com. Possible?

You would need an extended access token. It will only last up to 60 days and from then you would need to re-extend.
If it were a page you could extend the user access token then grab the page access token which would never expire.
