Hi, I'm new to okta, so please don't bite 😝
What I'm trying to achieve is after succesful user registration I want to imediately add the registered user id (it's 'sub' filed as I presume) to an external database, in which there will be another data (I don't want to mix login info with the user data, so the user id would be the only field in common), but I really don't know where to begin with it.

may hooks helps:

Hooks or SCIM connector or jobs using Okta APIs can help.
