Build a live guest queue

A host is live. Viewers ask to come on, the host picks who joins the stage, talks with them, then sends them back to the audience. The format behind live shopping, creator Q&As and call-in shows.

How it fits together​

  1. HostGoes liveJoins the room your server created.
  2. ViewerAsks to joinTurning on the mic or camera sends a request instead.
  3. MediaSFUQueues the requestThe host sees who is waiting and what they asked for.
  4. HostBrings them onAccepts, talks, then mutes or removes the guest.

Set it up​

  1. Create the room from your server with every media type on approval:

    curl -X POST https://mediasfu.com/v1/rooms \
      -H "Content-Type: application/json" \
      -H "Authorization: Bearer $MEDIASFU_API_USERNAME:$MEDIASFU_API_KEY" \
      -d '{"action":"create","userName":"host","duration":60,"capacity":200,"eventType":"webinar","meetingRoomParams":{"audioSetting":"approval","videoSetting":"approval","screenshareSetting":"approval","chatSetting":"allow"}}'

  2. For an audience larger than the room, add "recordingParams":{"recordingHLSSupport":true} and play the stream with the HLS guide.

  3. Let the host and viewers join from your app (below). Your server hands out the room details; the API key stays there (Secure backend).

Build it in your SDK​

Check it works​

  • Join as the host, then as two viewers on other devices.
  • Each viewer turns on their microphone. Two requests appear for the host; neither viewer is heard yet.
  • Accept one: that viewer is now on stage and audible. Reject the other: they stay in the audience.
  • Remove the guest from the stage, then end the session as the host.
