+### How to handle stream
+
+If you enabled stream, whenever a AI message should be streamed, you will receive that kind of JSON response:
+
+```json
+{
+  "messages": [],
+  "clientSideActions": [
+    {
+      "type": "stream",
+      "stream": true,
+      "expectsDedicatedReply": true
+    }
+  ]
+}
+```
+
+The bot is ready to accept the message streaming. You now need to send the following query:
+
+```sh
+curl -X POST https://typebot.co/api/v2/sessions/{sessionId}/streamMessage
+```
+
+Where `{sessionId}` should be replaced by the session ID you got from the start chat response.
+
+This endpoint will send Server-Sent events with all the information to display the streamed message.
+
+Once it is done, you can contine the flow by sending a [continue chat request](./chat/continue-chat) with the streamed message as the message content.
