By using this trigger, you can respond to your custom API events.
You can select a resource by double-clicking the External event trigger node.
An Interactions program will only be triggered if the size of event data for the given event is below 20kB. The API call will not trigger the Interactions program even if you get the 200 OK response.
You can filter External events based on the time when they were received by Interactions with the ems_event_time attribute.
