Manual TriggerThe manual trigger allows you to start a workflow by clicking a button
A workflow with a Manual Trigger will only run when you click the 'Run Workflow Now' button:
This is useful for when you have automated processes which only need to be kicked off exactly when you say - i.e. they are not scheduled, nor are they dependent on receiving input from other services.
The Manual Trigger is also very useful for setting up test workflows. It is very handy for triggering a workflow run, before checking the logs to see if it has worked and inspect the output results.
