I am trying to configure webhooks for events to post to a specified Slack channel. The channel already has the incoming-webhook app configured to post. I have created webhooks in Jamf pro pointing to the URL as JSON (tried XML too, no luck) but I just can't get it to post. I use the same channel for AutoPkgr notifications as well and those work fine.
I am not very Slack or Webhook savy, is there a step I am missing?
