Login with Apple OAuth2 + PHP Symfony redirect URI as GET

The "Login with Apple" redirects via POST method. I can't store the given token in a session because Symfony resets it if there is a POST request from crossdomains.

Is there any way to change the POST method to GET? All other OAuth2 applications are using GET and this works fine with PHP Symfony.
