FME Server Topic

The FME Server Topic trigger sends messages generated from FME Server Notification Service Topics.

The FME Server Topic trigger has two output ports. The success port (✔) can send a message if the trigger fails. The failure port (x) can send a message if the trigger succeeds.

Note: Use the Topic trigger only to initiate a workflow, or a portion of a workflow. It is otherwise not necessary to explicitly define topics for a workflow to run.

Parameters

  • Topics: Select the topic(s) you want to send messages.
