• In your Mattermost System Console, under Custom Integrations, check that these settings are enabled:
• Enable Incoming Webhooks
• Enable integrations to override usernames
• Enable integrations to override profile picture icons
• Enable Custom Slash Commands (if you want slash commands)
• Login to your team, click your name in the top left, then click Integrations

I think this document should be updated. A lot of this stuff is inaccurate… unless I’m using an older verion of mattermost but I do not think so…
