Rotation

Source: src/AWS/SSMContacts/Rotation.ts

An Incident Manager on-call rotation — a recurring schedule that rotates engagement duty between contacts. Attach rotations to an ONCALL_SCHEDULE contact via its engagement plan’s RotationIds.

Creating Rotations

const rotation = yield* SSMContacts.Rotation("Primary", {
  contactIds: [alice.contactArn, bob.contactArn],
  timeZoneId: "America/Los_Angeles",
  startTime: "2026-01-01T00:00:00Z",
  recurrence: {
    NumberOfOnCalls: 1,
    RecurrenceMultiplier: 1,
    DailySettings: [{ HourOfDay: 9, MinuteOfHour: 0 }],
  },
});
