Thank you for your reply.  However, when I wrap the endpoint in 
mywebapp::api with 'prefix' per your suggestion, I am still getting 404s 
on both 'http://localhost:5000/api/userdata/dancer_operator' and 
'http://localhost:5000/userdata/dancer_operator'.

Here is the diff of what I am trying:

So I'm still finding that 'appname' is not DWIMming.

Thank you very much.
