What's the difference between an active, , hidden, or inactive flow pattern?

Active flow patterns are those that are listed on the Submit a Flow page. You can submit these flows from this page or you can automate the submission using a flow service.

Some flow patterns, such as flow patterns used for system integration purposes, are only be available for submission though a service. The hidden option ensures these aren't displayed in the Submit Flow page.

Inactive flows are disabled and are no longer available for submission on the Submit a Flow page or through a service.
