To create a custom, real-time visualization dashboard, you would use the Juniper Mist APIs. The process requires two key functions: first, retrieving the static map and floorplan data, which is done using the RESTful API. Second, receiving the continuous, real-time location coordinates of clients on that map. This live stream of data is provided by the Mist WebSocket API, which is designed for efficient, low-latency, real-time data feeds. Combining these two APIs allows a developer to build a rich, interactive, and live location dashboard.

A. Live View is a pre-built feature within the Mist UI. You would use it to view a dashboard, not use it as a tool to create a new custom one.

C. Webhooks are used for sending event-driven notifications (e.g., an AP goes offline). They are not suitable for the high-frequency, continuous data stream needed for real-time location tracking.

1. Juniper Mist API Documentation, "Mist API". The documentation is structured into sections for "REST API" and "WebSocket API", indicating they serve different functions.

2. Juniper Mist API Documentation, "Maps". It details the REST API endpoint /api/v1/sites/:siteid/maps to "Get list of maps for a site," which is necessary to retrieve the floorplan image for the dashboard.

3. Juniper Mist API Documentation, "Location WebSocket API". It states, "The location websocket API provides a real-time feed of the location of wireless clients... This is the same API that powers the Mist 'Live View'." This confirms its use for creating real-time location visualizations.
