Hi,

Yes. You can get the IdTokenRaw from the AccessToken in the login result. However, this is a raw ID token string (JWT) without parsed, so you need to convert it to a JSON and get its email field manually. This is not convenient for now and we will add to our backlog! Before we can have a built-in way to parse it, you can try to find some other library or parse it yourself (Basically it is a base64 URL encoded string, and you can find a few existing libraries for this purpose.)

The detailed steps:

• Apply for OpenID and email permission in the developer portal console:

• Login with necessary scopes:

var scopes = new string[] {"profile", "openid", "email"};
LineSDK.Instance.Login(scopes, result => {
  //...
}

• Convert the raw string and get email

var raw = result.AccessToken.IdTokenRaw; // Remember to check null.
var jwt = SomeJWTLib.convertToDictionary(raw);
var email = jwt["email"]; // Remember to check null. Users can choose not allow you access the email.
