I am including a facebook Like/Share button on my webpage. I don't need anything more fancy than that, but the code still requires an app id. (I am using the "url" option from https://developers.facebook.com/docs/plugins/like-button/#settings)
Do I need to build a Facebook app just to include a like button on a page? And can this facebook app be in sandbox mode if I want to use the ID?
My code:
<iframe width="400" height="40" frameborder="0"
src="http://www.facebook.com/plugins/like.php?
href=http%3A%2F%2Fwww.myurl.nl&width=400&layout=standard
&action=like&show_faces=false&locale=nl_NL&share=true
&height=35&appId=MYAPPIDHERE"></iframe>
