Chain workflows, like a downstream extraction whenever an upstream one finishes or its data changes. Workflow triggers ## Create a trigger 1. Open a workflow → **Triggers** tab → **Add trigger**. 2. Choose when it fires: * **Data changed** — data changed between runs * **Workflow finished** — a run completed * **Export completed** — an export finished 3. Select the workflow to run → **Create trigger**. The target runs the next time the event fires. Toggle a trigger off to pause it without deleting. ## What you'll see * Workflows with triggers show a lightning icon and count in the dashboard table. * The **Triggers** tab lists outgoing triggers and, below, incoming triggers (workflows that start this one). ## Limits * Up to 5 triggers per workflow. * A workflow can't trigger itself. * Realtime workflows can't be targets. * Source and target must share the same team (or the same user for personal workflows). * A triggered run only starts if the target is active, not already running, and has no open support issue. Events that arrive mid-run are skipped, not queued. * Chains up to 5 levels deep to prevent loops. For time-based runs, see [Scheduling](/docs/ui/workflows/scheduling). To get notified of these events instead, see [Notifications](/docs/notifications).
