QoS Data Empty Most of the Time

API and Webhooks
1

The https://api.zoom.us/v2/videosdk/sessions/{sessionId}/users/qos endpoint seems to be returning data very inconsistently. We are attempting to use this during live sessions. Most of the time, the data looks like this:

        {
          "date_time": "2026-03-24T20:00:00Z",
          "audio_input": {
            "bitrate": "",
            "latency": "",
            "jitter": "",
            "avg_loss": "",
            "max_loss": ""
          },
          "audio_output": {
            "bitrate": "",
            "latency": "",
            "jitter": "",
            "avg_loss": "",
            "max_loss": ""
          },
          "video_input": {
            "bitrate": "",
            "latency": "",
            "jitter": "",
            "avg_loss": "",
            "max_loss": "",
            "resolution": "",
            "frame_rate": ""
          },
          "video_output": {
            "bitrate": "",
            "latency": "",
            "jitter": "",
            "avg_loss": "",
            "max_loss": "",
            "resolution": "",
            "frame_rate": ""
          },
          "as_input": {
            "bitrate": "",
            "latency": "",
            "jitter": "",
            "avg_loss": "",
            "max_loss": "",
            "resolution": "",
            "frame_rate": ""
          },
          "as_output": {
            "bitrate": "",
            "latency": "",
            "jitter": "",
            "avg_loss": "",
            "max_loss": "",
            "resolution": "",
            "frame_rate": ""
          },
          "cpu_usage": {},
          "cpu_pressure_level": {},
          "wifi_rssi": {}
        }

Sometimes, a few of the fields will return data.

I’ve seen previous threads where it was mentioned that this data does not return in the first minute of a session. This is happening long after the first minute. We also do have 2 users in the session, both with mic and camera on.

Is there any way to increase the quality of the quality of service data?

Hi @Jon-L
Thanks for reaching out to us .
I am happy to escalate this so our Engineering team can take a closer look.
Would you be able to share a tracking ID found in the response headers of your request
