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});

The Company I work with has many clients who uses Google Ads to do marketing for their websites. The company wants to use client's data for Analysis.
I am given a project to integrate Google Ads API using C# to get all the data such as Campaigns etc from Google ads and move it to our system for each client.
I am only given developer token and customerID for Clients.
such as
Customer ID for Client A
Customer ID for Client B
I am bit lost when I went through the google ads API documentation. In the documentation, the OAuth2.0 needs creating in order to use client library which would generate client ID and Client Secret, Refresh token to integrate the API.
My question is. Do I need to create OAuth2.0 for each client or do I need to ask my company to generate Client ID and secret in company's Manager Account or Client that uses Google ads would provide me these?
The following Link I found to create OAuth2.
https://developers.google.com/google-ads/api/docs/oauth/cloud-project
This is what I believe would require in C#
Content can be found at https://developers.google.com/adwords/api/docs/guides/first-api-call#.net_1
Would highly appreciate if any one can help me what actually I need to configure google ads using C#
If your company manager account is a manager for the relevant client accounts, you would just need to authenticate as the manager account using your developer token, client id and secret. This gives access to the Ads data for all clients linked under the manager account.
E.g. calling Google Ads API CustomerService > ListAccessibleCustomers returns a list of customers accessible to the authenticated client.
Further to comments where you say you will be creating a console app:
The link in your question says use a desktop application if:
You're managing all of your Google Ads accounts using a single top
level manager account. You're a first-time user, or want to get
started quickly with the simplest setup. Your app will only
authenticate Google users from one machine.
So using a manager account which links the required client accounts would be required in this case. See OAuth desktop application flow.
If you used a web application, the clients could log in and your app could read and store their refresh token in a database to make future calls to the api for their account.
You only need to create one application in the Google Console and have one Client ID and Client Secret for it.
Using that one set of credentials, you can go through the OAuth flow with each user to get an access token and refresh token for each of them. The access token, along with your Developer Token, will give you access to AdWords APIs for the user that granted it to you.
You need both your Developer Token and your user's Access Token in order to access the AdWords API.
If you're not as familiar with OAuth, you may look at a managed provider like Xkit (where I work). They have step-by-step instructions for accessing the Google AdWords API including how to generate the credentials and how to use them.
I am looking to integrate Gmail API in our .Net project (Both Windows & Web) so that user can send email or read users inbox, their list of folders (i.e. labels) and their respective mail to import in to our system.
During my initial research through google api documentation; Below are couple of questions come across:
For OAuth 2.0; OAuth credential needs to be created for type of application in google api console. I wanted to create wrapper around Gmail API (i.e. MyGmailAPIClass) so that same class can be shared between my windows & web projects along with common OAuth mechanism.
a. Do I need to create separate OAuth credential for Windows & Web and hence the OAuth implementation will differ based on type of application?
b. Can we use the same OAuth Credential for different types of application like windows, web or mobile apps? If yes; how can we achieve that?
I came across Service Account Credential stuff; Can we use that for application to access users email for sending and retrieving? How can we achieve that?
For Access and Refresh token; if we don’t store in some file or database; user consent screen will be prompted every time when user come to our application next time? I am not able to figure out valid use case for storing in file or database. The reason why I asked this because when In .net console sample; I turned off that mechanism after first successful sign-in when I again run the console sample again it will not show consent screen for granting permission?
Please suggest how should i proceed !! It would be good if someone can give any direction and also reference some working example.
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 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 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.
