# End Ambient After Streaming
> Send the RU9G end marker, close the WebSocket, then end the ambient session with REST
**Problem:** You close the WebSocket, but the ambient session never completes and no note is generated.
**Solution:** Send a final `AUDIO` frame with `"data": "RU9G"` (Base64 of ASCII `EOF`), close the socket, then `POST /api/v1/ambient/session/{ambient_session_id}/end`. Closing the socket alone is not enough.
This cookbook assumes you already have your Partner ID, authentication tokens, and an active ambient session with a WebSocket stream open.
```typescript theme={"theme":{"light":"github-dark","dark":"material-theme-darker"}}
// After the last PCM chunk on the ambient WebSocket:
ws.send(JSON.stringify({ type: "AUDIO", data: "RU9G" }));
ws.close();
const endRes = await fetch(
`https://sdp.suki.ai/api/v1/ambient/session/${ambientSessionId}/end`,
{
method: "POST",
headers: {
sdp_suki_token: sdpSukiToken,
sdp_provider_id: sdpProviderId,
},
}
);
if (!endRes.ok) {
throw new Error(`End ambient session failed: ${endRes.status}`);
}
// Then poll status before content APIs
```
```python theme={"theme":{"light":"github-dark","dark":"material-theme-darker"}}
import json
import requests
# After the last PCM chunk on the ambient WebSocket:
ws.send(json.dumps({"type": "AUDIO", "data": "RU9G"}))
ws.close()
end = requests.post(
f"https://sdp.suki.ai/api/v1/ambient/session/{ambient_session_id}/end",
headers={
"sdp_suki_token": sdp_suki_token,
"sdp_provider_id": sdp_provider_id,
},
)
end.raise_for_status()
# Then poll status before content APIs
```
## Common mistakes
* Close the WebSocket without sending `RU9G`.
* Send Dictation-style `AUDIO_END` on the ambient `/ws/stream` endpoint.
* Treat WebSocket close alone as session complete. You still need REST end, then status polling.
