Tasks are a way to execute your pipelines using a fixed schedule or by accessing a URL. The URL method of execution can also feed data into a pipeline and receive the output of the pipeline. From the Tasks page, you can view what tasks are already available and create new ones. Since the pipelines executed by tasks will be run in an unattended mode, you can receive notifications of activity by specifying a comma-separated list of email addresses.
If you are on the Tasks page under a project, the list will display what type of task each one is in the Run Policy column. If you are on the project-level page, this column is not available.
Hover over the task name to get access to the context menu. From there, you have access to view the task's activity log to see when it was created or modified.
