Provider – Google

Google Sample

Important notice

Google Apps created for Social Login now need to be verified by Google. Verification is required if your app is marked as Public. Before your consent screen and application are verified by Google, you can still test your application with some limitations, once the limitation is exceeded, users will receive a notification from Google, that the App is not verified and probably isn’t trustworthy.
So before proceeding, please have a look at the Unverified apps documentation which indicates how unverified apps may behave. If you would like to know more information about the verification it self, please check the OAuth Application Verification FAQ of Google.

Common error messages returned by Google during verification


Error: redirect_uri_mismatch
The redirect URI in the request,, (where the is your domain) does not match the ones authorized for the OAuth client.

Access blocked: This app’s request is invalid
You can’t sign in because this app sent an invalid request. You can try again later, or contact the developer about this issue. Learn more about this error
If you are a developer of this app, see error details.
Error 400: redirect_uri_mismatch

The problem is that the entered Authorized redirect URIs field is not correct for your app. Check the 19th step of the App setup to fix the problem.


Error: invalid_client The OAuth client was not found.

The entered Client ID is not correct. Maybe the app with the entered ID was deleted. Go to the Google provider → Settings and make sure that an existing App’s Client ID and Client Secret was entered.

Request is missing required authentication credential

Error: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See

The entered Client ID or Client Secret is not correct, it is probably contain some extra white-space characters. Make sure you copied the Client ID and the Client Secret in the appropriate format.

Error 403: org_internal

Error 403: org_internal
This client is restricted to users within its organization.

The “User Type” in your App was set to “Internal”. The problem is that, the internal Apps can only be used be the members of the organization. If the goal is to make the App being usable by everybody, the “External” User Type must be selected, as we suggested in the 7th step of the Getting Started Section.

Other 403 and 404 errors

When your other providers work properly, but your Google provider gives you 403 or 404 error, your server or firewall will most likely have a limitation that prevents accessing to pages with HTTP/HTTPS links in them. For more information please visit our Google 403 and 404 errors documentation.

Frequently Asked Questions

Why am I not logged in automatically after the version 3.0.19?

For a better user experience we modified our Google authentication related codes. So once the user was already logged in with the Google provider and logged out, then the person will have the opportunity to chose a different Google account.
It was a common problem that users logged in with a Google account other then the one they wanted, so they logged out from the site. But from this point, the login happened automatically with the selected account.
Fortunately Google offers an account selector scope, so starting from Nextend Social Login 3.0.19, the account selection box will be offered instead of the autologin. In this way users will be able to choose the account they would like to login with.
