SSE Streaming Event Reference (Generic)
Each business message is pushed through SSE as data: {json}\n\n. Parse messages by top-level type.
type | Meaning | Frontend handling suggestion |
|---|---|---|
system | Stream initialization event (usually subtype=init) | Extract session_id and pass it back as conversationId for follow-up turns |
assistant | Assistant output chunks (text/image/thinking, etc.) | Render as the main assistant stream |
user | SDK passthrough messages (usually tool execution output) | Mark as "tool output", do not treat as manually typed user input |
result | Success end signal for the current turn | Stop stream concatenation and mark completion |
error | Failure end signal for the current turn | Stop stream concatenation, show error, and allow retry |
done | Optional SDK passthrough end hint | Can be used to stop loading, but business completion should follow result / error |
Notes
- Heartbeats are SSE comment lines (for example
: heartbeat ...) instead ofdataevents, and can be ignored in business rendering.
