Oncall Relay reads your PagerDuty schedule and tags the right people in Slack — automatically, on a schedule you set, with upcoming rotations included.
Runs as a step inside Slack's own Workflow Builder. No dashboard to log into.
Most tools stop at the current shift. Oncall Relay shows the full picture — every level, every timezone, before the handoff even happens.
See who's covering as backup too, not just who's first in line — most tools only show the primary on-call.
"Starts Thu, 9:00 AM" means their morning, not yours. No more mental timezone math for distributed teams.
DM the incoming on-call person a configurable amount of time before their shift starts — so nobody finds out they're on call from an incident.
Authorize read-only access to your on-call schedules. Oncall Relay never sees or stores your PagerDuty credentials — Slack holds the connection.
Add the step to a Slack workflow. Choose the PagerDuty schedule, the channel to post in, and how many upcoming rotations to include (free plans: 1 schedule, current + next rotation — Pro removes both limits). Pro plans can also turn on direct DMs to whoever's tagged.
Slack's own scheduler triggers the post — daily, weekly, whatever cadence fits your team. No servers, no cron jobs to maintain.
Pro plans can add a second step that DMs the incoming on-call person a configurable amount of time before their shift starts — 15 minutes, an hour, a full day ahead, whatever fits.
Takes about two minutes. You'll connect PagerDuty and pick a channel from inside Slack.
