Get the first_name and last_name from $user_id after a new user registers on a Wordpress.

Hi I am trying to create a plugin that takes data for newly registered users and uses it to populate and external api POST. I can't get first_name or last_name though from $user_id when using the action user_register.

I understand they are values store in the usermeta tables but even if I use get_user_meta($user_id)) I still can't seem to find them, they turn up empty.

Any ideas?

Have you gone through user registration to verify that First/Last name is required?
