# Mattermost Integration

> Connect LemWatch alerts to a Mattermost channel via incoming webhook.

## Mattermost Integration

### Pro Plan and Above

 LemWatch posts a **Slack-compatible JSON payload** ( { text, attachments: [...] } ) to Mattermost. The same field also accepts catch-hook URLs from Zapier, Make, n8n, IFTTT, and Pipedream — see [Automation Recipes](https://lemwatch.com/help/automation-recipes).

### Setup

- In Mattermost: Main Menu → Integrations → Incoming Webhooks → Add Incoming Webhook .

- Pick the channel that should receive alerts, set the display name, and save.

- Copy the URL (looks like https://your-mattermost.example.com/hooks/abc123... ).

- In LemWatch: Settings → Notifications → Mattermost / Automation webhook → paste and save.

- Click Send test to verify.

### Self-hosted notes

- Any HTTPS host works as long as it accepts a Slack-style JSON POST.

- LemWatch blocks private/loopback IPs and non-HTTPS URLs at the server (SSRF protection).

- If you front Mattermost with a reverse proxy, make sure the proxy forwards the raw JSON body.

### Message format

- Severity-coloured attachment header (red / yellow / green).

- Site name, URL, alert type, and current metric values.

- A direct link back to the LemWatch dashboard.
