      • If you set the Event Source Type parameter to Alibaba Cloud Service Event Sources:

        Select an Alibaba Cloud service from the Event Source drop-down list and an event type from the Event Type drop-down list.

        Note

        Events from Alibaba Cloud services cannot be published to custom event buses. Therefore, you cannot set the Event Source Type parameter to Alibaba Cloud Service Event Source if the event bus that you use is a custom event bus.

      • If you set the Event Source Type parameter to Custom Event Source:

        Select a custom event source from the Event Source drop-down list and specify an event pattern in the Pattern Content code editor.
