I’d like to do some external automations when a topic is moved from category A to category B. Specifically, I want to remove all comments from the topic when that happens. To achieve this, it seems I need to catch a webhook when the topic is moved, and do it then.
I see there is a webhook event header of topic_edited. The issue I see is that it seems to offer no relevant data about the category it was moved from.
Any suggestions on the best way to achieve this?
