+### Server-Sent Events (SSE)
+
+All streaming endpoints also support [Server-Sent Events (SSE)](https://www.w3.org/TR/2012/WD-eventsource-20120426/). SSE is a standard protocol that enables servers to push data to clients over HTTP, and is natively supported by most browsers and HTTP client libraries.
+
+To use SSE, include the following header when establishing your connection:
+
+```
+Content-Type: text/event-stream
+```

+SSE support is currently available on the staging environment only. This will be rolled out to production in a future update.
