Available Triggers & Actions

Microsoft Outlook Calendar logo

Microsoft Outlook Calendar

Triggers (5)

Because deleted events cannot be re-fetched from the Outlook API after deletion, this trigger emits notification metadata only (not the full event object). The emitted payload includes the deleted event identifier (eventId), changeType, subscriptionId, tenantId, and notificationTimestamp. Downstream processors must rely solely on this metadata. See the documentation

webhook
New Calendar Event Update (Instant)

webhook
New Upcoming Calendar Event
