Answer 1

When Google return the Authentication Code code to your Socialite, it can only be used to exchange to Access Token once. Doing more than once will result in the error Code was already redeemed.

The flow should be:

1. User click the login button on your website
2. You redirect user to Google and Google is asking user to login/grant you access
3. If successful, Google redirects back to you with a one-time-use Authentication Code?code=.....
4. Socialite use the ?code and exchange it with Google to get user's Access Token. This can only be done once per flow.
5. You can now request user details using the access token requested in step 4.
