Hi Natalia,
You can still use the weblinks feature and have your event set up to be invitation only. Within your registration paths, you'll want to set up the settings as seen in the screenshot below so that only those on invitation lists are able to register for the event and they are able to register via email and through the event website.

This means that anyone who is not uploaded to one of your invitation lists will not be able to register for the event and you can still create registration type or path specific weblinks and send those out to attendees via email so that they are directed to the correct registration path when they click on the link.
