Hi OzanB,
I also needed to get Tulip Data into PowerBI for analysis. The only way I could get Tulip data in was through Power Query or Python using the code some nice people in this community created.
Power Query: getallTulipTableRecords in Excel
Python: Guide: Using the Table API and Python to import data from a Tulip Table into Power BI - #3 by stefan
Downside is that Power Query and Python related data extraction does not work in web based Power BI. On top of that, the python query will only work if the computer running the refresh also has python.
I think it would be an amazing improvement if data between Tulip and Power BI could be refreshable in the web client for easier sharing of reports.
