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