To get the ID information needed to put into your Crowdcast, you would need to setup a Pixel and get the code. There is a good article from Facebook on how to do so setup a Pixel.
Where do I find my Pixel ID?
There are two ways to obtain your Pixel ID.
Log in to Facebook and go to your Ads Manager account.
Open the Navigation Bar and select Events Manager.
