Realtime: SSE and WebSocket

Render the answer as it streams instead of waiting for the agent turn to finish.

POST chat/stream: same parameters as /chat, text/event-stream response.
Events: session (sessionId), token (partial text), final (complete answer), error.
WebSocket: /re-act namespace for bidirectional realtime.

Streaming — JavaScript (fetch + SSE)

const res = await fetch("https://api.votredomaine.com/api/v1/re-act-agent/chat/stream", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ botId: "VOTRE_BOT_ID", sessionId, msisdn: "0700000000", message }),
});
const reader = res.body.getReader();
const dec = new TextDecoder();
let buf = "";
while (true) {
  const { done, value } = await reader.read();
  if (done) break;
  buf += dec.decode(value, { stream: true });
  const parts = buf.split("\n\n");
  buf = parts.pop() ?? "";
  for (const evt of parts) {
    if (!evt.startsWith("data: ")) continue;
    const msg = JSON.parse(evt.slice(6));
    if (msg.type === "token") append(msg.delta);    // texte partiel
    if (msg.type === "final") finish(msg.content);  // réponse complète
    if (msg.type === "error") fail(msg.message);
  }
