What is the use of the "xd_receiver.htm" file?





Appreciate if you can like this page if you find it useful! - Click "Like"

The "xd_receiver.htm" file is the cross-domain communication channel file that enable communication between your website and Facebook. This file is used by the old JavaScript Client Library (some people refer this as the "Connect Library") only.

While you have question on this, I believe you are new in developing application on Facebook or integrating Facebook to your websites. In such case, I strongly suggest using the JavaScript SDK instead of using the old JavaScript Client Library.
