Interacting with Viewers

Updated: Jul 2, 2026

Copy for LLM

You can use the Live Video API to get comments and reactions on live video broadcasts so that video producers and on-air talent can interact with viewers. You can get comments and reactions by periodically querying the LiveVideo object to get current comments and reactions, or set up Server-Sent Events to receive real-time comments and reactions.

Getting current comments and reactions

To get the current comments or reactions on a live video broadcast, send a request to:

GET /{live-video-id}/comments
GET /{live-video-id}/reactions

Sample request

Select language

curl -i -X GET \
  "https://graph.facebook.com/{live-video-id}/comments?access_token={access-token}"

Sample response

{
  "data": [
    {
      "created_time": "2018-08-30T18:47:02+0000",
      "from": {
        "name": "Steph C.",
        "id": "552524095105158"
      },
      "message": "This is such a great live stream.",
      "id": "911936075671494_911936769004758"
    },
    {
      "created_time": "2018-08-30T18:47:17+0000",
      "from": {
        "name": "Kevin D.",
        "id": "552524095105158"
      },
      "message": "Shoutout over here!",
      "id": "911936075671494_911936909004744"
    },
    {
      "created_time": "2018-08-30T18:48:14+0000",
      "from": {
        "name": "Clay T.",
        "id": "552524095105158"
      },
      "message": "Where is this place?",
      "id": "911936075671494_911937292338039"
    }
    ],
  "paging": {
    "cursors": {
      "before": "WTI5d...",
      "after": "WTI5d..."
    }
  }
}

Receiving real-time comments and reactions

To receive comments and reactions in browser clients in real-time, set up Server Sent Events and send a request to these endpoints:

GET /{live-video-id}/live_comments
GET /{live-video-id}/live_reactions

Note that the host URL for streaming events is: https://streaming-graph.facebook.com

Sample request

Select language

GET https://streaming-graph.facebook.com/{live-video-id}/live_comments?access_token={access-token}
