# NB: There are several other pieces of code which route requests by URL:
#
#   - legacy_urls.py contains API endpoint written before the redesign
#     and should not be added to.
#
#   - runtornado.py has its own URL list for Tornado views.  See the
#     invocation of web.Application in that file.
#
#   - The Nginx config knows which URLs to route to Django or Tornado.
#
#   - Likewise for the local dev server in tools/run-dev.py.

# These endpoints constitute the currently designed API (V1), which uses:
# * 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
#
# All of these paths are accessed by either a /json or /api/v1 prefix;
# e.g. `PATCH /json/realm` or `PATCH /api/v1/realm`.
