I want my bot (Microsoft Bot Framework in C#) to access my google calendar so that I and others who chat with the bot can view upcoming events. Most of the Google Docs I found show how to authorize a New User's own Google Calendar (https://developers.google.com/google-apps/calendar/quickstart/dotnet and the OAuth 2.0 library)), but I do not want the bot to access the specific User's calendar, just one specific calendar every time.
Will the bot need to authorize repeatedly to view this one calendar? Am I able to embed the credentials in the code so Users are not prompted for Authorization?
Thanks :)
Try using Google Service Accounts.
The Google OAuth 2.0 system supports server-to-server interactions such as those between a web application and a Google service. For this scenario you need a service account, which is an account that belongs to your application instead of to an individual end user. Your application calls Google APIs on behalf of the service account, so users aren't directly involved. This scenario is sometimes called "two-legged OAuth," or "2LO." (The related term "three-legged OAuth" refers to scenarios in which your application calls Google APIs on behalf of end users, and in which user consent is sometimes required.) Typically, an application uses a service account when the application uses Google APIs to work with its own data rather than a user's data.

I need help.
I need to create an app, which takes all events from different calendars from my company, and display them in computers in conferences rooms. This is created, works good. To authenticate I use Oauth 2.0 like google wants, but I tested it only on my computer. When the app was launched on the computer in the conference room, the app needed logging into google account, which surprised me, because I put my oauth 2.0 credentials into my code, so I thought that this would be enough.
How can I skip that part, to authenticate only from code level and not display Oauth popup message to user?
When you run your code locally you are authorizing it. If you are using the official Google api .net client library then it is storing your authorization credentials in the %appdata% folder on your machine. Once you move this to the computers in the conference rooms they have not been authorized and there for will require that you authorize them. So you should be able to just run it once on each machine and authorize it and it will be all set.
If you do however have a google workspace account, I would recommend you look into using a service account and configuring domain wide delegation this would stream line your process a bit.
The following example shows how to use a service account with domain wide deligation.
var credential = GoogleCredential.FromFile(PathToServiceAccountKeyFile)
.CreateWithUser("user#yourdomain.com") // delegate to user on workspace.
.CreateScoped(new[] {CalendarService.ScopeConstants.Calendar});
I am writing an application in C# which would run on a PC and allow a user to login to GCP and manage files there.
I looked at the sample codes on https://cloud.google.com/storage/docs/reference/libraries
The documents show how to use a service account for authentication, but I want to use user authentication.
In this way, if the user do not have permission to say delete data, the application can not do it. If I use a service account, which I don't want.
Is there any way that I use user authentication to log in to cloud storage services?
Is there any sample that I can use for this purpose?
Update 1
My main aim is to develop an application similar to gsutil but in C# and it should authenticate users similar to gsutils.
The same as gsutil, it would be used only by cloud admins who already have access to buckets via gsutils or cloud.google.com
Is the source code for gsutils published? How does it authenticate users?
What you might be wanted to use is this "User account credentials". This at the ends guides you to Firebase Authentication, which supports email and password authentication as well as federated sign in with identity providers such as Google, Facebook, Twitter, and GitHub.
You can sign in users to your Firebase app either by using FirebaseUI as a complete drop-in auth solution or by using the Firebase Authentication SDK to manually integrate one or several sign-in methods into your app. This will be up to your needs and how you want to build your app.
I am setting up a WebAPI that needs to collect events from a calendar, located in sharepoint. The WebAPI is registered i Azure Portal and does not support user login. Can i restrict the application to only that one calendar, or only have access to a specific users calendars?
This is what i currently have.
A WebAPI ( .Net Core 2.1 )
Azure AD with a bunch of users
Registered in Azure Portal, with Application "Calendars.Read" permissions
Using TenantID/ClientID/ClientSecret when authentication the app, and have not user login for the webserver, and would prefer not to have user login if possible.
As of now, i can pull the events with Microsoft graph by using something like:
https://graph.microsoft.com/v1.0/sites/root/lists/4bddc7ee-xyz-xyz-83cc-/blablabla
The problem is that i have access to all users calendars, and i need to restrict the app to only have access to that specific calendar.
I have seen several similar questions like this, the answer is No, Microsoft Graph does not support that currently.
I am just starting out with a windows azure mobile services .net backend, and am running into so many headaches as a new programmer. I have gone into my azure mobile services account and downloaded the todoitems demo app (c# for .net backend). I then followed the tutorials regarding adding facebook authentication, but I am absolutely not pleased by this method, as it shuts down the app for a few seconds. As such, I set out determined to create a custom authentication login page which ties to my mobile backend.
I found this article and thought, "Great!" only to realize that I had no clue how to catch a user created account from a textbox and to pass it along to the public class RegistrationRequest. The example at the end of the link shows how to connect to a local machine - but I want it to connect to my actual database at the following location: https://mycustomapp.azure-mobile.net, return a token, and continueon.
What is frustrating is that I am able to obtain a facebook authentication token, as well as user information. BUT, I have no idea how to generate a windows azure mobile auth token so that the client may write/retrieve data from my azure table.
Essentially my question is this - using the above link, how in the world may I take a user's username and password from a textbox, run it through the RegistrationRequest, and not have to pop advil on this? Do I need to pass my facebook token? I assume not?
I am also not using a facebook SDK or anything like that - simply put, I am using the above site's code trying to get an auth token from my azure mobile services, despite having one from facebook already, to authenticate a user against my azure mobile services data table.
If you already have a FB token, the easiest way to login to your mobile service is by using the FB token, then you don't need to make a custom UI/etc.
This can be done by calling
var token = new JObject();
token.Add("access_token", "access_token_value");
await client.LoginAsync(MobileServiceAuthenticationProvider.Facebook, token);
see: http://azure.microsoft.com/en-us/documentation/articles/mobile-services-windows-dotnet-how-to-use-client-library/#authentication, Client Flow for more
if you want to login to your service with a Facebook account, you do not need to implement a custom authentication and to capture user name and password in your own textbox controls.
You should be able to use MobileServiceClient.LoginAsync() and pass as parameters the provider that you want to use. Check this article fro more information.
As an organisation, we use Google Apps. We have the paid version (mapped to our domain) etc...
We are developing a web based application to manage orders, and other business functionality.
I want to be able to use federated login with our google apps accounts-
For example, if a user is logged in to their email (gMail) - they should automatically be logged in to our ASP.net application
If they're not logged in - the log in form should auth. against our google apps account.
How can this be done?
Is it possible to be able to "get" the user who is currently logged in using this method etc...?
Sure, use dotNetOpenAuth. It's recommended by OpenId library and it should be easy in use. As far as google provides OpenId interface there should be no problem with using it in your application.
Stackoverflow is successfully using it and I'm logged here always when I'm logged on my google account.
Just doing a quick search through Google's API documentation, it sounds like you need to use Google's implementation of OAuth protocol.
If you have not yet started developing, you could even considering developing for Appengine - using python or Java (though I would prefer Python myself).
Advantage is that it has a much closer integration with Google Apps services and it will be much easier to build further functionality that works with Google apps (docs/mail etc). Besides this, there arent too many hassles for hosting the app.
