Why is the state parameter not available in Auth0 Pre-Registration Hook?

Hi @norbert.juhasz,

Welcome to the Auth0 Community!

Can you confirm you are talking about Hooks? Please note that Hooks/Rules are now read-only ahead of their deprecation. If you are referring to the Pre-User Registration Action Trigger, unfortunately, it is not possible to access query string parameters. Please see here for more: Accessing Query String Parameters in a Pre-User Registration Action

Thanks,

Mary Beth
