Hey guys, working on a massive Zendesk to Genesys Cloud migration and hitting a wall. We need to build a custom wallboard that shows live agent status (Available, On Queue, Away) for hundreds of agents. Right now, I wrote a script that just loops through all the users and hits the GET /api/v2/users/{id}/presences endpoint every 10 seconds. It works, but we are absolutely hammering the API rate limits and getting 429 errors during peak hours. What is the correct way to get real-time status updates without pulling the data manually every few seconds?
Oh man, I did the exact same thing when we first rolled out our custom dashboard for our 800 agents here in Tokyo. You definitely cannot poll the presence API for that many users, it will break the platform limits instantly! You have to switch over to the Notification API. You basically open a WebSocket connection and subscribe to the v2.users.{id}.presence topics for your agents.
Once you subscribe, the Genesys server just pushes the status changes directly to your dashboard whenever an agent clicks a new status. No polling required!
That WebSocket approach is amazing for lightweight dashboards! But if you are building an enterprise wallboard that needs to aggregate data and maybe pipe it into other systems, you should definitely look into AWS EventBridge! It is a total game changer! Instead of managing WebSocket connections and worrying about reconnect logic in the browser, you just tell Genesys Cloud to stream all the presence events directly to your AWS account. You can hook the EventBridge up to an AWS Lambda function and update a DynamoDB table, and then your wallboard just reads from the database! It scales flawlessly!
EventBridge is fine for backend systems, but if you actually try to build a pure frontend dashboard with WebSockets, prepare for a headache. The Notification API restricts you to 1000 topic subscriptions per WebSocket channel. If you have 800 agents, you use up your entire channel capacity just subscribing to presence events, leaving no room for routing status or active conversation topics.
Furthermore, WebSockets randomly disconnect, meaning you have to write a ton of complex reconnect logic and resubscribe to all 800 topics every time the connection drops. It is incredibly tedious to manage.
