How can I programmatically read Power Query dataflow metadata?

[scurrp]

I want to return metadata like the power query dataflow name so if the name changes the metadata will reflect the updated name. 

What I'm thinking is a number of system variables that can be queried in the dataflow:
Something like
_.dataflow.Name - this is the name of the dataflow that is indicated in the title
_.dataflow.TableName

_.dataflow.WorkspaceName

The only way to read metadata about dataflows is using the REST API. See Dataflows - REST API (Power BI Power BI REST APIs) | Microsoft Learn

Some of what you want is there, but not everything directly. The Get Dataflow command though will export the entire dataflow definition to a JSON file, and that will have table names, column names, even column data types. You will just need to parse out the JSON file.
