webhook missing callbacks to detect when messages are posted
The webhooks thing doesnt seem to provide a way to monitor an activity stream. My idea for a custom webhook integration is to post a GUID to a channel occasionally (because Glip doesnt have permalink support but does have infinite backlog fulltext search support) but only if there is activity in the channel. With the existing webhook API, I cant determine from my script if there is activity or not. Itd be pointless for me to post a bunch of GUIDs when nobodys talking.
How am I supposed to write a webhook integration like this without access to the activity stream?
