      "ref": "github.com/project-flogo/contrib/trigger/channel",
      "handlers": [
        {
          "settings": {
            "channel": "test"
          },
          "action": {
            "ref": "github.com/project-flogo/flow",
            "settings": {
                "flowURI": "res://flow:testflow"
            }       
          }
