Automated flows can call any Common Data Service action
As a part of reaching parity with the Common Data Service Workflows, automated flows can now call all actions that are available in Common Data Service. This includes everything from fulfilling a sales order to exporting an Excel file. Actions represent operations that might have side effects in the database, such as creating or updating records. An Action might require parameters and might return a value, and can be associated with certain records.
These actions include the out-of-box SDK messages, process and custom actions, and even custom workflow activities.
