Getting date of birth from Google OAuth API in MVC

Question

I added the following areas to access data from the user

#region Google var googleAuthenticationOptions = new GoogleOAuth2AuthenticationOptions() { ClientId = ConfigurationManager.AppSettings["Google_AppID"], ClientSecret = ConfigurationManager.AppSettings["Google_AppSecret"] }; googleAuthenticationOptions.Scope.Add("profile"); googleAuthenticationOptions.Scope.Add("email"); googleAuthenticationOptions.Provider = new GoogleOAuth2AuthenticationProvider() { OnAuthenticated = async context => { //context.Identity.AddClaim(new Claim("birthday", context.User.GetValue("birthday").ToString())); string claimType; bool bAddClaim = false; foreach (var claim in context.User) { claimType = string.Empty; bAddClaim = false; switch (claim.Key) { case "given_name": claimType = "FirstName"; bAddClaim = true; break; case "family_name": claimType = "LastName"; bAddClaim = true; break; case "gender": claimType = "gender"; bAddClaim = true; break; } if (bAddClaim) { string claimValue = claim.Value.ToString(); if (!context.Identity.HasClaim(claimType, claimValue)) context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Google")); } } } }; 

When debugging in context.user in a side foreach loop, setting a breakpoint I get the following information

  {
 "sub": "101111724115925537597",
 "name": "Alok Nath",
 "given_name": "Alok",
 "family_name": "Nath",
 "profile": "https://plus.google.com/101111724115925537597",
 "picture": "https://lh3.googleusercontent.com/XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/
           photo.jpg ",
 "email": " [e-mail] ",
 "email_verified": true,
 "gender": "male",
 "locale": "en"
 }

So, even after adding the "profile" area, I do not get the birthday as part of the return value. I made sure that the profile has the appearance of a birthday, open to the public, i.e. It is visible to everyone. Is there any specific area or specific settings that I need to make in order to receive a birthday from Google ?

Or is there a way to solve this problem, please post a solution

It seems to me that you need to set the scope https://www.googleapis.com/auth/plus.login to get the date of birth suggested by this stackoverflow user:
