External Triggers (Magic xpi 4.1)

External triggers do not run in a trigger worker thread in a managed engine. Instead, they run in their own processes and create flow invocation requests originating from other applications.

The HTTP trigger, for example, is a module running under a web server (IIS or Apache). The SOAP Web services trigger is another example of an external trigger invoked by the Systinet server.

External triggers are typically synchronous.
