How to create a messenger user over REST API

Hello Members,

I would like to create messenger users and then associate them with GW users over REST API. According to the documentation I need to do a POST operation to this url "/domains/{domain}/postoffices/{postoffice}/users/{user}/messengerlink/{messengerId}" and I have to pass over data also. But what data? The documentation lists every possible attribute to post. Do I really have to dump every GW user attribute and pass it to messenger? Even the moveStatus array? Or is there a minimum required attribute list?

TIA,
Gellért
