Laravel Socialite Google login only with one domain - laravel

Question

I have a Google+ login on my app with Laravel Socialite. When the login is done I have a callback to connect the user (I create her in database if necessary).
But I want to restrain the connection to only the company (email like "example#company.com", so only the email with "company.com").
Can I do it with Laravel Socialite ? I can make the verification manually in my callback but if Socialite can do it, it's better.
Thank you
My callback :
public function handleProviderCallback($provider){
$user = Socialite::driver($provider)->user();
if ($user) {
$local_user = User::whereEmail($user->getEmail())->first();
// If we don't have a user create a new user
if (!$local_user) {
$fragment = explode(' ', $user->getName());
$local_user = User::create([
'first_name' => isset($fragment[0]) ? $fragment[0] : '',
'last_name' => isset($fragment[1]) ? $fragment[1] : '',
'email' => $user->getEmail(),
'last_seen' => Carbon::now(),
'password' => ''
]);
$local_user->roles()->attach(Role::whereName('User')->first());
}
auth()->login($local_user);
}
return redirect($this->redirectTo);
}

You have a step by step guide for domain restriction.
In controller you need to specifiy these actions:
public function handleProviderCallback()
{
try {
$user = Socialite::driver('google')->user();
} catch (\Exception $e) {
return redirect('/login');
}
// only allow people with #company.com to login
if(explode("#", $user->email)[1] !== 'company.com'){
return redirect()->to('/');
}
// check if they're an existing user
$existingUser = User::where('email', $user->email)->first();
if($existingUser){
// log them in
auth()->login($existingUser, true);
} else {
// create a new user
$newUser = new User;
$newUser->name = $user->name;
$newUser->email = $user->email;
$newUser->google_id = $user->id;
$newUser->avatar = $user->avatar;
$newUser->avatar_original = $user->avatar_original;
$newUser->save();
auth()->login($newUser, true);
}
return redirect()->to('/home');
}

No, you can’t do it in Socialite itself because Socialite is just a mechanism of retrieving tokens from OAuth-compliant servers.
If you only want to accept users with a particular email suffix, then that’s business logic so something you should handle in your callback:
public function handleProviderCallback()
{
$user = Socialite::driver('google')->user();
if (Str::endsWith($user->getEmail(), '#example.com')) {
// Look up user and authenticate them
}
abort(400, 'User does not belong to organization');
}
