Can a Rails app send messages through Signal Messenger?

I'm trying to figure out if it's possible to have a Rails application send messages to user via Signal messenger (as opposed to an email or SMS).

Has anyone tried to do this?

Have you tried yet? I'm trying to try it, but still no results.

It's not easy Madalin Stunt Cars.

One problem as I understand it is signal needs a phone number. It uses this for it's encryption protocol somehow, or so I've read.

I use the signal windows desktop app alot. My ROR app server is an Ubuntu server environment. Curious if Signal could be installed on ubuntu, linked to my current number and used via the command line.

Recent research shows signal-cli to be promising, but is resource intensive.
