 The link below shows how to define an endpoint and parse headers and json content. It doesn't show how to configure Flask for HTTPS, but is fairly straightforward:
 http://flask.pocoo.org/snippets/111/
 
+You can also link an httpbin service to the development environment for testing webhooks using:
+
+```
+make docker-compose-notifications
+```
+
+This will create an `httpbin` service reachable from the awx container at `http://httpbin/post`, `http://httpbin/put`, etc. Outside of the container, you can reach the service at `http://localhost:8204`.
