Build your first on-call rotation
Five team members, weekly handoff Monday 9am. Five minutes.
Build your first on-call rotation
Make sure your team exists
Go to On-Call → Team. The list shows everyone in your workspace.
Missing people? Click Invite member, enter their email + role. They get an email with a magic link — when they accept, they appear here.
Create the schedule
Switch to On-Call → Schedules, click + New schedule.
Fill in:
- Name — "Engineering On-Call" (or whatever)
- Slack channel (optional but recommended) — pick the channel where pages should land. Searchable; polls every 5 seconds while open in case you create one in Slack.
Leave Layers (1) showing one Primary layer. Inside that layer:
- Rotation — Weekly
- Handoff day — Monday
- Handoff time — 9:00 AM
- Timezone — your team's main TZ
- When is this layer active? — Always on-duty (24/7)
- Rotation order — Click Add all to add every team member, then drag to reorder. Each person on top will take the first shift.
Create the schedule
Click Create Schedule. The Currently On-Call banner appears at the top showing the first person + how long until handoff.
Wire alerts to it
Open any monitor's alert rule, toggle Notify on-call, optionally pick this schedule. Now when that monitor goes down, the alert posts to the schedule's Slack channel and @-mentions whoever is on call.
Test the flow: schedule's Test button fires a synthetic page. The current on-call person sees it in Slack within ~2 seconds.
Link your Slack identity
Go to Settings → Integrations → Slack identity. Click Auto-match by email — Happy Uptime calls Slack's users.lookupByEmail, finds you, stores your slack_id. Now alerts can @-mention you specifically.
Each team member should do this for themselves (or use the Link team by email bulk button on the Team tab — admin only).
What you got
- A weekly rotation that hands off every Monday at 9am in your timezone, even across DST.
- A Slack channel that gets paged when monitors fire, with @-mentions of whoever is on call right now.
- An iCalendar URL (Schedule card → ICS button) you can subscribe to in Google Calendar / Outlook.
