I’m running the sample app here: https://github.com/zoom/rtms-developer-preview-js
It appears to work successfully, but no media data is ever received. It gets meeting.rtms_stopped after about 30 seconds of running. These are the full logs:

This is the RTMS code I was running, I would have expected it to receive audio data
// Import the RTMS SDK
import rtms from "@zoom/rtms";
// Set up webhook event handler to receive RTMS events from Zoom
rtms.onWebhookEvent(({ event, payload }) => {
console.log(`Received webhook event: ${event}`);
// Only process webhook events for RTMS start notifications
if (event !== "meeting.rtms_started") {
console.log(`Received event ${event}, ignorsding...`);
return;
}
// Create a client instance for this specific meeting
const client = new rtms.Client();
// Configure HD video (720p H.264 at 30fps)
client.setAudioParameters({
contentType: rtms.AudioContentType.RAW_AUDIO,
codec: rtms.AudioCodec.OPUS,
sampleRate: 16000,
channel: rtms.AudioChannel.MONO,
dataOpt: rtms.AudioDataOption.AUDIO_MIXED_STREAM,
duration: 20,
frameSize: 320
});
// Set up audio data handler
client.onAudioData((data, size, timestamp, metadata) => {
console.log(`Audio data: ${size} bytes from ${metadata.userName}`);
});
// Set up transcript data handler
client.onTranscriptData((data, size, timestamp, metadata) => {
console.log(`${metadata.userName}: ${data}`);
});
// Join the meeting using the webhook payload directly
let joinResult = client.join(payload);
console.log(`Join result: ${joinResult}`);
});
Does the home URL for my zoom app need to link to a functional zoom app? Currently it just points to a localhost url that doesn’t do anything, so the zoom app displays a blank screen. Auto-start is enabled for the zoom app though and the webhook url is pointing to ngrok. So unclear if you need a functional home url AND a webhook url or if you just need a webhook url.
Update: Here’s some feedback that something is going wrong. In the zoom client you see this for a about 30 seconds
then it says connection failed and we get the rtms.stopped event
