You can use DBus to post notifications to the panel under wayland. There is a command-line utility to make it easy to post them. From a terminal:
wfpanelctl notify "a message"
or
wfpanelctl critical "a critical message"
If you look in /usr/bin/wfpanelctl, you can see how the DBus access works.
Under X, there is a much simpler mechanism whereby the application can be directly messaged - the equivalent of wfpanelctl is lxpanelctl, so
lxpanelctl notify "a message"
wfpanelctl notify "a message"
or
wfpanelctl critical "a critical message"
