Problem
We’re pushing real-time queue analytics notifications to our internal Kafka cluster. The Genesys Cloud UI shows the notification subscription active, but the Node.js consumer keeps dropping messages after the first batch. The subscription payload looks correct in the admin panel, yet the stream closes unexpectedly. Our Pacific region org usually handles this fine, but the queue dashboard metrics stall completely. The routing settings are standard, nothing fancy. The admin panel shows the subscription ID matching our config.
Code
const ws = new WebSocket('wss://api.mypurecloud.com/api/v2/analytics/notifications/stream');
ws.on('open', () => {
ws.send(JSON.stringify({
subscriptionType: 'realtime',
entities: ['queue:8a7b9c1d-2e3f-4a5b-6c7d-8e9f0a1b2c3d'],
metric: 'queueStats'
}));
});
ws.on('message', (data) => {
console.log('Received:', data.toString());
producer.send({ topic: 'genesys-queue-stats', messages: [{ value: data.toString() }] });
});
Error
Network traces show the server sending a ping, but our client never responds. The connection establishes fine, but after roughly 15 seconds, the socket emits a close event with code 1001. No 401 or 403 errors show up in the logs. The Kafka producer confirms it received the first three payloads, then the stream just stops. We’ve verified the OAuth bearer token has the analytics:read scope. The payload structure also shifts slightly after the initial burst, which breaks our schema validation. Memory spikes right before the disconnect. We can’t replicate the issue on staging.
Question
How do we keep this WebSocket alive without triggering the 1001 close code? The docs mention a heartbeat mechanism, but the implementation details feel scattered. Any ideas on the keep-alive header setup
