Are you using Tableau Online, or Tableau Server.
In Server, you can access the repository which will give you this information, but dont think that you can get at it when using Online.
I'm not sure that you can get this information using the REST API though
Thanks for the quick response. I'm using Tableau Online and the REST API, unfortunately.
I may use the Tableau Server in the future, so it's good to know the information is available.
