I am trying to query the iTunes U API to return a list of all of the details in my iTunes U site. I am using the /API/ShowTree call detailed in the documentation but I am getting the following XML return:
<error>Command not allowed</error>
I have been able to do this in a previous site that has not been migrated to use the Public Site Manager so I am wondering if there is a difference in the APIs between versions? If so is there a new call or better yet an updated version of the docs that I can review to better understand the differences?
