Google OAuth API to get user's email address?

Question

I am playing with Google\'s OAuth 2.0 Playground using my own personal Google account, but I cannot seem to recover my Gmail address using the playground.

The scope

Answer 1

To retrieve the email address, you need to include the scope: "https://www.googleapis.com/auth/userinfo.email" as mentioned in this document. If this scope is included while you generate the refresh token, you should be able to get the email address of the authenticating user by making the following request:

you can call this with your own access token then will give the response

https://www.googleapis.com/oauth2/v3/userinfo?access_token="YOUR_ACCESS_TOKEN"

response will look like this

{
  "sub": "1057abc98136861333615xz",
  "name": "My Name",
  "given_name": "My",
  "family_name": "Name",
  "picture": "https://lh3.googleusercontent.com/a-/AOh14qiJarwP9rRw7IzxO40anYi4pTTAU_xseuRPFeeYFg",
  "email": "MyName@gmail.com",
  "email_verified": true,
  "locale": "en"
}

or simply you can just write a function

import requests
def get_user_email(access_token):
    r = requests.get(
            'https://www.googleapis.com/oauth2/v3/userinfo',
            params={'access_token': access_token})
    return r.json()
