Building node site to manage ga-auth-keys data group

I have a node site built which can help manage the ga-auth-keys data group used in the Google Auth APM process. However, I need a way to force a sync between my two F5 units in an HA pair after I add a user and key to the data-group. I have tried /cm/traffic-group, but it doesn't have the ID of the active unit, that I can tell. Also, I cannot figure out how to force a sync using the tmsh shell commands.

I will be posting the node app, once I get this completed.
