Google API C# SDK get profile email

Question

We're integrating Google api C# SDK to our application and following Google "web application" workflow. We need to retrieve currently authenticated Google user email.

We get it works using one of these approaches:

Directly make http request to https://www.googleapis.com/oauth2/v1/userinfo?alt=json&access_token=xxx .
Use Google people api C# sdk

    var peopleService = new PeopleServiceService(new BaseClientService.Initializer { HttpClientInitializer = result.Credential, ApplicationName = "Test App" });
    
    var peopleRequest = peopleService.People.Get("people/me");
    peopleRequest.RequestMaskIncludeField = new List<string> { "person.EmailAddresses" };

    var profile = peopleRequest.Execute();

Use Google Gmail api C# sdk

    var gmailService = new Google.Apis.Gmail.v1.GmailService(new BaseClientService.Initializer                                                                     
        {
            HttpClientInitializer = result.Credential, ApplicationName = "Test App"                                                                    
        });

    var gmailProfile = gmailService.Users.GetProfile("me").Execute();
    var userGmailEmail = gmailProfile.EmailAddress;

Scopes we're using are:

"https://www.googleapis.com/auth/gmail.readonly" "email" "profile"

Examples above work well, however we don't want to use https://www.googleapis.com/auth/gmail.readonly as it's "restricted" scope.

So, we wonder if there any chance to call the Google profile email using some method from C# SDK ?

Thanks in advance, Evgeny.

Profile scope will give you access to google people api however i think you need to user.emails.read to get access to their email address.

https://www.googleapis.com/auth/user.emails.read View your email addresses

using a gmail scope seems like overkill if you just want the users email address. Which api are you using in general some of them have ways of getting the users email.
