It’s messy, but if you setup both a Post and a Topic webhook. When a message, or topic is first created, both hooks will be fired. You can use the `topic_id` that is sent with the Post webhook to get the topic `archetype` from the topic webhook data. It will be set to ‘private\_message’ for messages, ‘regular’ for regular topics.

It would be great to get some topic data sent with the Post webhook - `category_id` and `archetype` would both be useful.
