Hi @flappix, the instructions you’re looking at in the link that you referenced (https://docs.mattermost.com/developer/webhooks-incoming.html#how-do-i-send-a-webhook-post-to-a-direct-message-channel) is for Direct Messages (meaning a channel with you and one other user or yourself). I’m not sure if it works for Group Messages or private channels with more than 2 users. In the first example that you posted a week ago, are you the user “test”?
