The Predictive dialing mode in Genesys Cloud CX places multiple calls per available agent and uses algorithms to predict agent availability, aiming to maximize agent talk time by reducing idle time between calls.

A query endpoint provides real-time access to the most up-to-date data and returns the requested information immediately. This is ideal for scenarios where the user requires immediate responses.
A jobs endpoint, on the other hand, is designed for scenarios where bulk export of data is required. It processes requests asynchronously and provides a response when the export is complete, making it suitable for larger data sets that don't require an immediate response.

In the Genesys Cloud CX Notifications API, ping/pong messages are used to check the healthof the WebSocket connection. These messages help detect if the socket is still open or if it has been dropped, enabling appropriate client-side handling.
