Exposing streaming API to provide real time updates to the user
Opens a new event stream according to your request filters. Unlike our other APIs, a request to /api/events/ returns a stream of data, where each line is a JSON object. The response body contains all the events in that stream. Since streams by definition go on forever, Real-time Data Streaming will never end the response without some external reason.
