Requesting that Auth0 propagate /authorize parameters (like redirect_uri, state, ui_locales) through Actions event objects and Liquid template variables would benefit many use cases.
Use-case: If a client has multiple registered callback urls we need to know where to redirect it after confirming email, change password…to improve user experience. Also we want email templates to be translated on different languages ( if client sends ui_locales query string). This should be also available in custom-email-provider action (and some other like post-change-password) if don’t use built in email providers.
