Integrating with HTTP Servers
HTTP Wait-Notify
HTTP Wait-Notify is a step, configured with a post url, that can be added to a workflow. The workflow data is posted to this url when the task is executed. A call back url is included in the post. The workflow and task are suspended until the receiver posts back.
Processing form data POSTed to your web server is described in the Submissions Stored Outside of frevvo.
