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 I am using is:
email profile https://www.googleapis.com/auth/plus.login
But when I call the API:
https://www.googleapis.com/oauth2/v2/userinfo
I get various information about the user such as family name, first name, gender, picture, etc. but it does not return the user's email.
How do I retrieve the user's email address? Do I have the wrong scope or am I calling the wrong API? I feel like this should be very simple but I have literally been trying to figure this out for hours and I cannot find an API and scope combination that consistently provides the user's email address.
Update: December 2018
On December 20th, Google announced that the Google+ API would be turned down in March 2019, with intermittent failure starting at the end of January 2019. As part of the the plus.people.get
endpoint is deprecated and scheduled to be terminated.
The userinfo
endpoint is de-deprecated (see clarification) and should provide the info assuming
https://developers.google.com/identity/sign-in/web/devconsole-project
scope andemail
field.Clarification: 24 Jan 2019
Google documented that the userinfo (v2) endpoint was deprecated, but later changed it to "deprecated, but kept available for backwards compatibility".
Current documentation discusses getting profile and email information through the currently supported openid
method. This includes using the "userinfo" endpoint specified in their discovery document, as required by OpenID Connect.
At the moment, that URL is https://openidconnect.googleapis.com/v1/userinfo
, but this has changed in the past and the discovery document at https://accounts.google.com/.well-known/openid-configuration
is the authoritative source for the URL to use.
So, to be clear:
Regardless, the plus version of anything (described below) is deprecated and scheduled to be removed.
Original Answer
There are a lot of issues here in what you're doing and how you're trying to do it.
For starters, the https://www.googleapis.com/oauth2/v2/userinfo
endpoint is deprecated, and scheduled to be removed in September 2014. It has begun working inconsistently - so don't use it.
As @abraham noted, you'll use the people.get endpoint at https://www.googleapis.com/plus/v1/people/me
. This should give you the emails field containing an array of addresses. In your case, there will likely be only one that has a type of "account".
As of 2017: use the email
scope. See Authorizing API requests.
This email scope is equivalent to and replaces the https://www.googleapis.com/auth/userinfo.email scope.
For signing in with Google using OAuth 2.0, there's no need to make a separate request to get user's email.
When Google calls the callback URL, it provides a code
in the query string that you could use to exchange for access token and ID token. The ID token is a JWT that contains identity information about the user, which includes the email address.
See more information here: https://developers.google.com/identity/protocols/oauth2/openid-connect
You'll want to add the https://www.googleapis.com/auth/userinfo.email
scope or replace https://www.googleapis.com/oauth2/v2/userinfo
with it. If you're using the HTML example they provide, you can list multiple scopes separated by a space.
<span
class="g-signin"
data-callback="signInCallback"
data-clientid="{{ plus_id }}"
data-cookiepolicy="single_host_origin"
data-requestvisibleactions="http://schemas.google.com/AddActivity"
data-scope="https://www.googleapis.com/auth/plus.login
https://www.googleapis.com/auth/userinfo.email">
</span>
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": "[email protected]",
"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()
