Slack Integration

Send monitor alerts to Slack channels using incoming webhooks. Get notified when monitors go down or recover.

How It Works

Uptime Monitor sends alerts to Slack using incoming webhooks. When a monitor goes down or recovers, a formatted message is posted to your configured channel.

  • •Monitor name appears as a clickable link to the dashboard
  • •Down alerts show the error reason
  • •Recovery alerts include total downtime
