Steps
Discover /api/events and /api/alarms hrefs from GET /api; a plain GET on these is short-poll and returns immediately (empty if nothing new)
Follow the updates.href on each (GET /api/events/updates, /api/alarms/updates) to long-poll — the call blocks until new items arrive or a timeout (~50s) elapses
Re-issue the request against the next/updates link returned in the response body to continue the stream
For monitoring many specific items at once, POST /api/items/updates with an itemIds array to create a subscription, then long-poll GET /api/items/updates?bookmark=... for changes instead of polling each item individually
Re-fetch the item-updates subscription within its short validity window (about 30s) or it is dropped and must be recreated
Known gotchas
There is no websocket or webhook push mechanism — all 'real-time' delivery is HTTP long-polling that must be continuously re-issued
An item-updates subscription expires quickly if not immediately re-GET, silently going stale
POST /api/events can also be used to inject third-party events into Command Centre, which is a different operation from reading them
