where
- subscription_id − subscription ID (set arbitrarily in UUID format; mandatory parameter).
- event_type - event type (optional parameter).
- subject - subject of the event (detectors in this example; optional parameter).
To
...
receive events using a subscription,
...
do the following:
- Run a request with the PullEvents method.
After receiving the "200 OK" response, the events will be accumulated. - After the required time interval, run a request with the DisconnectEventChannel method.
You will receive a list of events that occurred between the two requests.
The request body with the DisconnectEventChannel method:
