Webhooks is a great addition to Discourse! I’d like to +1 @r3trosteve’s earlier comment:
Triggering webhooks on a “Badge Event” would be incredibly useful. We could use these to toggle on permissions in external applications when badges are earned in Discourse (e.g., you can edit our wiki once you’ve earned trust level 2 in our forum).
Extra credit: reduce unnecessary traffic by allowing badge events to be scoped to specific badge(s)
