Althpough it is not yet available or documented, you can still start preparing your add-in for the day when it comes
– Aspects to consider
– Accessing the Revit
– DB application add-in manifest
– Next steps...
One important step to take before trying to run your Revit API code fully automated and unattended is to ensure that it does not create or modify UI in any way. For example, you must ensure that it does not cause Revit to display any warnings. This can be achieved with a warning swallower. Let's implement one for the StairsAutomation SDK sample...

How to export all the Revit data to an external database?
It is very simple to extract all the parameter data.
Let's implement a solution to do so
– Existing sample implementations
– Black box input
– Choices for the output and its structure
– Retrieve parameter values from an element
– FilterCategoryRule versus category filters
– Category description extension method
– Retrieve parameter data for all elements of given categories
– External command
– Sample run results

Today brings a nice gift from Andrey Bushman – NuGet Revit API package – RevitLookup using the NuGet Revit API package – Creating a NuGet package from assembly DLLs – More NuGet packages...
I am happy to present a pretty comprehensive overview and explanation of the process of defining a shared parameter by Scott Conover.
Question: What do I need to do to programmatically create a shared parameter? I would like to set the
SetAllowVaryBetweenGroups flag on it.
Answer: You create the details needed to define a shared parameter from
Existing shared parameter file entries can be read to become an
ExternalDefinition in your code, or you can create a new entry in the current shared parameter file using the
