I am using `Sitecore 8.1  (rev. 160519)`. In Sitecore `FXM` experience editor I have added one placeholder and component on it and publish all these changes, but it is not reflected on External Site. 

There are no errors in the FXM log files and the component is showing correctly in the FXM Experience Editor. When I try to figure out the external app post call request all was good but the component data is not present in the post call response. 

There is also one capture click action which is working fine on external site and the click event is also getting captured in Sitecore Analytics. But the added component is not showing on external site. 

Below is the response for the external site post call ,
