Application Integration supports several types of listener-based connectors that can be used for event-based processing of messages and files. Process Designer exposes a wide range of attributes in the connectors so you can use many file listener properties when you configure a listener-based connection.
These connectors, like the AMQP Connector (message-based) and File Connector (file/storage-based), act as message brokers or file monitors that can be reused to make data objects, service calls, and events available to the Process Designer.
