Settings → Notifications takes a webhook URL: a Slack incoming webhook, a Discord webhook, or anything from Zapier, Make or n8n.
Once set, you get:
- A daily summary at 9:30am your time: what the checks did the day before, plus what's waiting on you, oldest first. Nothing is sent on an empty day.
- An alert when a check fails for a business or when something needs a person right now.
Send a test confirms the URL before you rely on it.
