Workflow modules
The workflow structure is essentially made up of modules and their connections. Which modules you need, which service the module executes and which settings are required for the module is described below for each module.
From time to time workflow modules are replaced by versions with more setting options or new modules. The old modules that still appear in the workflows continue to function, but are no longer present in the pool of workflows provided for use. Consequently, they cannot be used in workflows that need to be created or cannot be restored if they are deleted in an existing workflow.
These old modules should be replaced promptly with the new versions. You can recognize these modules by the fact that they are marked with a red exclamation point.
