# Triggers (/docs/concepts/triggers)

The three trigger types that start a workflow execution.



A trigger is the event that starts a workflow run. Workflows use trigger nodes to define how they start. Manual and cron triggers are limited to one per workflow. Webhook triggers can have multiple.

When to use which [#when-to-use-which]

* **Manual** - prototyping, debugging, human-in-the-loop flows
* **Webhook** - reacting to external events (price alerts, GitHub pushes, form submissions)
* **Cron** - periodic checks (portfolio snapshots, token monitoring, scheduled reports)
