I am writing a REST API client and, at some point, I need to obtain a list of workspaces of the particular Marketo account. Is it possible? I could not find such endpoint at the Marketo REST API documentation.
What are you looking to do with a Workspace? I think lead partitions might be more what you are looking for? http://developers.marketo.com/blog/how-to-specify-lead-partitions-using-the-rest-api/
