// Once you have determined the height you'd like the iFrame to conform to...
// inform Pulsar SFS of that height formatted as you would CSS.
var myHeight = "800px";

window.parent.postMessage({
  "type": "refresh",
  "height": myHeight
}, "*");

// Note: sending "*" as the origin is acceptable since this will never carry sensitive data
// Note 2: sending "*" as the height tells FSL to size the iFrame to fill the available space in the view port
