I can 'become' a user in the UI but when I try to use a token to do it in the API, I get this error:
curl -v "https://canvas.test.instructure.com/api/v1/users/self/activity_stream?as_user_id=99999999000000082" -H "Authorization: Bearer `cat sis@canvas-test`"
I've tried using the format (faked id here) "as_user_id=sis_user_id:322323" too...same result
in the 2nd case I got the user id via
curl -v "https://canvas.test.instructure.com/api/v1/accounts/99999999000000001/users?search_term=stuff" -H "Authorization: Bearer blahblah
What do I have wrong here?
