Scheduler
Triggering flows
Overview
The Scheduler Helper allows you to trigger flow runs automatically at regular interval or just once.
The Scheduler Helper must be the first step in the Flow. To activate the scheduler, set the Flow to status active.
Actions
The Scheduler Helper has only one default action - Schedule Flows.
On the screenshot, you see the options you have for scheduling flows:
Start Date Time
Required
The Start Date Time Is required to determine the first time a flow should ever run.
The time you take is your local time and is converted to UTC in the background. Meaning, that if your browser time-zone is based in London and you set the Start Date Time to start at 9 am, this will trigger a flow at 10 am Central European time.
End Date Time
Optional
The End Date Time sets until which date time a Flow should be scheduled. This is entirely optional as a flow may run indefinitely.
Interval
Required
The Interval is the crucial piece of every scheduler and has the following options:
every 5 mins - Runs every 5 minutes
every 15 mins - Runs every 15 minutes
every hour - runs hourly
daily - runs every day regardless of any selection of weekdays
weekly - runs every week on the specified weekdays
monthly - The flow will run monthly on the same day of the month. For example, if the start date is the 11 of March, the flow will always run on the 11th of each following month until the end date or if it is not chosen, indefinitely. Each case: If you schedule it on the 30 of June, the flow will always run on the 30th of each month, and in the case of February, having usually only 28 days, the flow will run on the last day of February. Meaning, that if a month has fewer days than the chosen day, the flow will run on the last day of the month. We found that this serves most business cases and hopefully also yours.
once - Only runs once ever
custom - Runs according to the set Custom Interval
Custom Interval (Minutes)
Required and only takes effect for Interval custom
When the Interval is set to custom, the Custom Interval (Minutes) must be used. The minimum interval is 5 minutes and the maximum is 1440 minutes (1 day).
Weekdays (required for interval weekly)
Required and only takes effect for Interval weekly
When the Interval is set to weekly, Weekdays needs to be used. If no days are selected (and the interval is weekly), then the flow will be scheduled to run on all days.
Allow Parallel Flow Executions
Optional
The Allow Parallel Flow Executions setting determines whether Flow Runs are allowed to run in parallel if they are triggered by the Scheduler. Parallel Flow Execution happens if the Scheduler interval is set to a shorter time than the Flow Run duration (e.g. the interval is set to every5mins, but the Flow Run takes 12 minutes).
If it's allowed (default), the next Flow Run (and all following ones) will happen as scheduled
If it's not allowed, all scheduled Flow Runs will be skipped (appearing with status skipped in the Flow Debugger) until there are no more running Flow Runs that were triggered by the Scheduler
This only applies to Flow Runs where the currently running and the run that might be canceled were triggered by the Scheduler. Thus, when manually triggering a Flow and then a scheduled Flow Run happens, the scheduled Flow Run will not be canceled, even if the manually triggered Flow Run is still running.
