Configure apple sign in, a good starting point is the blog of Aaron Parecki

Add the following variables in your .env file:

SOCIAL_CLIENTID_APPLE=YOUR_APPLE_CLIENT_ID

SOCIAL_CLIENT_SECRET_APPLE=Client_secret

SOCIAL_REDIRECT_APPLE=/social-auth/handle/apple/

The following points should be considered in order to use the apple provider in socialite:

You only get the email address in the first login of the user. You should save the email address (user->email) and the apple identifier (sub) (user->id). The second time you use this identifier to find the user in your laravel applications. See SocialAuthController -> getHandleCallback

Add your authorization handle post request in the VerifyCsrfToken, in this example:

 protected $except = [
        '/social-auth/handle/apple'
    ];

Refresh the client_secret apple key each six months (write a automatic cronjob)

A cronjob example with client.rb:

#!/usr/bin/env bash

source /usr/local/rvm/environments/ruby-2.6.3

cd /your_path_apple_sign_in/

ruby client.rb > apple_client.txt

/bin/cp -f apple_client.txt /your_laravel_path/storage/apple/apple_client.txt

chown your_linux_user/your_linux_group /your_laravel_path/storage/apple/apple_client.txt

Other solution to refresh your client secret, see comment alinmiron

If the user is using his anonymous email-address, a standard email relay (mandrill, sendgrid) is not possible at this moment.

Succesfull login: Save your_apple_identifer as apple_identifier in your db and [email protected] 
user->email, you only get the email once!!), 
for the development you could delete your apple app https://appleid.apple.com/account/manage 
(security ->  to test this again

• Invalid grant: check that your client_id and client_secret has the same service_id.
• Timeout

• Initiate the apple request again, state is invalid.
