# NB: There are several other pieces of code which route requests by URL:
#
#   - legacy_urls.py contains API endpoint written before the redesign

#
#   - runtornado.py has its own URL list for Tornado views.  See the

#

# * REST verbs
# * Basic auth (username:password is email:apiKey)
# * Take and return json-formatted data
#
# If you're adding a new endpoint to the code that requires authentication,
# please add it here.
# See rest_dispatch in zerver.lib.rest for an explanation of auth methods used
#
