+## Event Hooks
+
+`requests` allows event hooks to mutate `Request` and `Response` objects. See [examples](https://requests.readthedocs.io/en/master/user/advanced/#event-hooks) given in the documentation for `requests`.
+
+In HTTPX, event hooks may access properties of requests and responses, but event hook callbacks cannot mutate the original request/response. 
+
+If you are looking for more control, consider checking out [Custom Transports](advanced.md#custom-transports).
