Could not obtain Google oAuth 2 token on POSTMan

Question

Well, since the Other problem(solved) remain unsolved, I was thinking to use POSTMan to do Trial and Error on each steps that the Client library will do.

So I read the Basic steps of Google OAuth2 again, created another OAuth 2 ID at Api Manager > Credentials in Dev Console and ID type is Web Application, and filled them into the POSTMan:

1. New tab in POSTMan, then click the Authorization label.
2. Choose type as OAuth 2.0 and select "Add token to the url"
3. Auth URL: https://accounts.google.com/o/oauth2/v2/auth
4. Access Token URL: https://www.googleapis.com/oauth2/v4/token
5. Client ID: [the Client ID that I just received]
6. Client Secret: [the Client secret that I just received]
7. Scope: [empty]
8. Grant Type: Authorization Code
9. Request access token locally: Selected
10. Click "Request Token"
11. POSTMan replied me: "Could not complete OAuth2.0 login"

Do I missed something?

Answer 1

BigHomie's suggestion of scope to 'email' worked for me as well. But I used a different Auth URL and Access Token URL than BigHomie, because I think it's been updated.

Auth URL: https://accounts.google.com/o/oauth2/auth

Access Token URL: https://accounts.google.com/o/oauth2/token
