Custom members integrations with web app?

I would like to know if it is possible to integrate my web app’s member login to my webflow site? For example, a user logged into my web app and my webflow site would be notify and understand this current user is logged in and webflow CMS is only showing (not just hiding content in front-end-client but CMS does not send data to the front-end client) the user certain contents? Is such integration possible?
