Scheduled Trigger
The Scheduled trigger automatically starts a workflow at a configured execution frequency — no human intervention needed.
Overview
Configure timing rules through the frequency selector — no need to manually write Cron expressions — the panel auto-generates and live-previews the Cron expression based on your selections. Four frequency modes are supported: every N minutes, every N hours, daily at a fixed time, and weekly on specific days.

Execution Mode
Triggers support two execution modes, determining which page the workflow runs on:
| Mode | Description | Configuration Required |
|---|---|---|
| Open New Tab | Opens a new browser tab, loads the specified URL, then executes | Execution Page URL (required) |
| Match Open Page | Matches an already-open tab by URL pattern, executes on the matched page | Match Pattern (Chrome match patterns format; see URL Match Patterns) |
The Execution Page URL supports referencing received data via {{variableName}} (see Variables), enabling dynamic target page selection. Match patterns are fixed and do not support variables.
FAQ
The scheduled task didn't execute at the configured time
Symptom: The configured time has passed, but the workflow didn't start.
Cause: The browser is in a sleep state, or the tab isn't active, causing the browser to throttle the timer.
Solution: Enable the "Activate Tab" toggle to ensure auto-focus when triggered; confirm that the browser's background running permission is enabled.
