Mattermost

Receive clear, formatted alerts in your Mattermost channel (Cloud or self-hosted).

Setup

1. In Mattermost, make sure Incoming Webhooks are enabled (System Console → Integrations → Integration Management).
2. Go to Integrations → Incoming Webhooks → Add Incoming Webhook.
3. Choose the channel, save, and copy the Webhook URL (https://your-server/hooks/...).
4. In AlertHub, open the project Connections tab and click the Mattermost card.
5. Paste the Mattermost URL and save.

The Mattermost server must be reachable over HTTPS from the internet. AlertHub sends an attachment with project, level, title, and description. Warning and critical alerts are delivered; info stays in the dashboard.
