End Ambient After Streaming

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.

Python

// 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

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.
