What is the correct way to handle dynamic script injection via AppFoundry?

General Discussion

What is the standard approach to inject dynamic content into an active agent script from an external AppFoundry integration without triggering a full page reload or losing the agent’s current interaction context?

Our premium app needs to update script fields based on real-time data from our backend. Currently, we are attempting to use the purecloud:agent-script event to push updates, but the UI does not reflect the changes immediately. The agent sees a stale version until they manually refresh, which breaks the conversational flow.

Environment details:

  • Genesys Cloud Platform (Standard Edition)
  • AppFoundry SDK v2.4.1
  • Architect Flow: Simple script playback with custom fields
  • Browser: Chrome 120+ (Windows)

We have verified that the API call to update the script data succeeds with a 200 OK response. The issue seems to be in the client-side synchronization. Is there a specific method in the SDK to force a re-render of the script component, or should we be using a different approach entirely? We want to avoid polling the API every second, as that seems inefficient and risks hitting rate limits during high-volume periods.

Any guidance on best practices for real-time script updates would be appreciated.

You need to use the purecloud:agent-script:update event instead of the standard push. This triggers a targeted DOM update without reloading the interaction context.

window.dispatchEvent(new CustomEvent('purecloud:agent-script:update', { detail: newData }));

This is a standard event emission pattern, but ensure your AppFoundry app registers the listener correctly.

window.addEventListener('purecloud:agent-script:update', (e) => { console.log(e.detail); });

Missing the listener often causes the silent failure described above. Check the browser console for errors.

Make sure you verify the event payload structure before dispatching, as malformed data often causes silent failures in the script engine. The purecloud:agent-script:update event is indeed the correct mechanism for targeted DOM updates without reloading the interaction context. However, ensure the detail object matches the expected schema for the specific script widget you are targeting.

  • Define the update payload with clear key-value pairs.
  • Dispatch the custom event on the main window object.
  • Listen for the event in your AppFoundry app to confirm receipt.
const updatePayload = {
 fieldId: "dynamic_note",
 value: "New real-time data"
};

window.dispatchEvent(new CustomEvent('purecloud:agent-script:update', { 
 detail: updatePayload 
}));

This pattern avoids full page reloads and preserves agent context. Testing with JMeter showed that rapid updates can still cause UI lag if the event frequency is too high. Consider batching updates or adding a debounce function if you are pushing data at high throughput rates during peak load. The listener registration mentioned above is critical; missing it leads to the stale UI issue described.
