Trigger Engine
Schedule Triggers (Cron)
Execute workflows at specified intervals using standard cron expressions. Schedules are evaluated by the Hub and rebuilt on Hub startup. Updating a schedule trigger restarts the schedule with the new expression.
| Expression | Schedule |
|---|---|
| 0 9 * * 1-5 | Every weekday at 09:00 |
| */15 * * * * | Every 15 minutes |
| 0 0 1 * * | First day of every month at midnight |
Webhook Triggers
Expose unique HTTP endpoints for external systems. The Hub issues a unique webhook URL per trigger; the URL itself acts as the credential. Disabled triggers reject incoming requests.
Retry Model
Queue-level: bounded retries with exponential backoff. Execution-level: one automatic re-queue if a runner goes offline during ASSIGNED state. No automatic retry of failed executions at the trigger level.
