Getting status updates from Front

Good morning,
I’m trying to sync the Front conversation statuses in Front with our internal data so we can display them to our users in our app. We just need to get the Open/Waiting/Resolved value from the conversations. I'm playing with the application webhooks, as recommended in your docs, but I cannot find an event that reacts to a change in these statuses (there are some internal status changed events but for Waiting and Resolved are, internally, the same “archived” status so nothing triggers in this case). I’ve gone around this issue by creating a custom rule that adds a tag when the status changes so I can receive the “Tag added” event but then I’m getting a lot of events that are not actually changing the status… The other solution will be polling directly the API but given the API request per minute restriction, if the inflow of tickets grows it might not be realistic. Is there anything else we can do, or something that we are missing? Thanks in advance,
Ruben
