+Now let's add urls
 
+```
+from django.urls import path
+
+from .views import (
+  ChatSessionView, ChatSessionMessageView
+)
+
+urlpatterns += [
+  path('chats/', ChatSessionView.as_view()),
+  path('chats/<uri>/', ChatSessionView.as_view()),
+  path('chats/<uri>/messages/', ChatSessionMessageView.as_view()),
+]
+```
+
+Also include chat urls in base urls
+
+```
+urlpatterns += [
+    path('auth/', include('djoser.urls')),
+    path('auth/', include('djoser.urls.authtoken')),
+    path('api/', include('chat.urls')),
+]
+```
+
+Our endpoints are ready and any AUTHENTICATED user make requests to them
+
+Let’s try it out in **terminal** or **cmd**:
+
+```
+# command
+curl -X POST http://127.0.0.1:8000/auth/token/create/ --data "username=admin&password=trydjango"
+
+# output
+{"auth_token":"6e6b6b6f4f1efe2e3f88db8dbec8da74cc556cf6"}

+# put auth_token in next command
+curl -X POST http://127.0.0.1:8000/api/chats/ -H "Authorization: Token 6e6b6b6f4f1efe2e3f88db8dbec8da74cc556cf6"
