What it does
A team’s owner or admin adds a webhook in the Mattermost format and picks the events. Each arrives as a Markdown message with a link; board text is escaped and @ is replaced, so nothing on a board can ping @channel, @all or @here.
Webhooks only ever tell a channel about boards the whole team can open: never personal boards or private projects.
Connect Mattermost
Step 1
In Mattermost, go to Integrations → Incoming Webhooks, add one for the channel and copy its URL.
Step 2
In your team’s admin console → Webhooks, add an endpoint with that URL, the Mattermost format and the events you want.
Webhooks are on unless the server’s operator set WEBHOOKS=false.
In Freero, Apps & agents → Mattermost takes you straight to this step.
