I have had trouble downloading workbooks using Tableau's REST API. I've been able to do a majority of Tableau's REST API calls without issue, but downloading workbooks makes it extremely hard to write to a file. Are there any code samples explaining how to do this? My language of choice is Python, if that helps. Thanks!
Can you give more details? What response are you getting when you make the call to the server to download the workbook?
Also note that if you are downloading a packaged workbook, you will get the extract as well, which in some cases can be very large and cumbersome to download.
