Google API How to get email alias for user?

Question

Question

Using Google OAuth for authentication, how can I get user email aliases?

I can not find any API docs on how to do this. What are the required areas and what is the right call to get this information?

Why

Let's say I have a user Alice who invites to [e-mail] the application. Unfortunately, [e-mail] is actually an alias for [e-mail]. When Bob enters the Google OAuth service, Google reports his email address [e-mail]. Now I accidentally created two accounts for Bob when I want to recognize them as the same account.

You can use the Google People API for this. Here is the documentation . The volume you need to use: https://www.googleapis.com/auth/user.addresses.read

This will return all the email addresses for the user and also tell you what is primary.
