For anyone using the new style SharePoint lists, there is now a new action for Microsoft Flow integration. It’s a really cool product that integrates all the Office 365 products (and more) into your workflow.
SharePoint Designer workflows still have their place but the Microsoft Flow interface offers rich functionality and is easy to view and structure workflows.
One downside to using Microsoft Flow is the error messages. They come back as error messages from the REST API as headers which can be very confusing for non-technical users. SharePoint Designer errors were much clearer and easy to understand for general users.
