AppleIdToken

This gem is a simple wrapper around Apple Sign In to validate provided tokens from https://developer.apple.com/documentation/sign_in_with_apple/generate_and_validate_tokens. You can also send tokens provided by official Apple library for iOS and Android applications.

We make use of JWT Ruby gem -> https://github.com/jwt/ruby-jwt to decode token provided by Apple and also it makes all the validations mentioned here -> https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_rest_api/verifying_a_user to ensure integrity of provided token.

Add this line to your application's Gemfile:

gem 'apple_id_token'

And then execute:

$ bundle

Or install it yourself as:

$ gem install apple_id_token

To make use of the gem, just call .validate method of AppleIdToken::Validator. You need to provide token issued by Apple and also your APP_ID generated here -> https://help.apple.com/developer-account/#/devde676e696 as audience.

validator = AppleIdToken::Validator
begin
  payload = validator.validate(token: token, aud: audience)
  user_id = payload['sub']
  email = payload['email']
rescue AppleIdToken::PublicKeysError => e
  report "Provided keys are invalid: #{e}"
rescue AppleIdToken::ValidationError => e
  report "Cannot validate: #{e}"
end
