I am in the process of setting up Slack webhooks for all of our Campaign alerting. However, I can't find if its possible to intercept any alerts generated to the workflow supervisor. It looks like they are generated directly by the server and not processed in any workflows.
Right now, the only way I have to find failed workflows and send alerts is polling the nl.monitoring API which seems a bit hacky.
Can someone confirm if you can intercept the workflow supervisor alerts?
