A bus is a logical entity that groups events and links connectors, which send events to the bus from external sources, with rules that process events and deliver them to targets.
An event is a JSON object delivered to the bus in one of these ways:
- Via a connector.
- Via the EventService/Put gRPC API call. You can use the API to deliver user events.
For more information about sending events to a bus, see Sending events to the bus.
An event is considered processed when all targets of all triggered rules return a successful response, or when the event is moved to a dead-letter queue.
