Facebook requires publishers to have a registered Website Facebook App in order to do native sharing inside FB. By default, we use our own Marfeel account, but if you already have one registered, we could replace this with your own App ID.
You might want to use your own Facebook App ID so that when your content is shared, users will see where it came from and know where to get more of it. 

Get your own Facebook App

If you don’t have an App and would like to create one, here's a guide on how to configure it:
  1. Go to Website Facebook App and click on Add a new App.
  2. Choose Website platform and configure with your own URL.
  3. Make it public.
Share your ID with Marfeel and we'll do the configuration for you.
