# Triggers

Trigger

Triggers are the starting point of every workflow. They monitor for events and fire when their conditions are met, producing an output payload that flows downstream to connected nodes.

Trigger nodes have no inlet ports — they only produce data through their outlet. Each trigger type watches for a specific kind of event: file system changes, scheduled intervals, application lifecycle, incoming HTTP requests, clipboard activity, keyboard shortcuts, system events, and more.
