Must I use an App ID with Facebook? It’s a hassle
We have chosen to encourage the use of Facebook App ID because that’s the overall direction that Facebook wants to take. We think that this will enable future-proofing and ensure that your web application doesn’t break and you can benefit from future developments to Facebook’s APIs.

There are no settings or custom functions. Set custom post types to be sticky just as you would with regular posts, and those post id’s will be included in the result of <code>get_option( 'sticky_posts' )</code>.
PLEASE NOTE In order to integrate as seamlessly as possible, this plugin will not alter any queries or filter any functions. If your sticky posts aren’t appearing the way you want, there’s probably a good reason in your query (Is <code>ignore_sticky_posts</code> set to <code>true</code>? Is <code>post_type</code> set to a different type?). This plugin may be most appropriate for developers who just want the native sticky post UI and no other superfluous features.
If you find this plugin useful, please rate it accordingly.

Seamless Sticky Custom Post Types

Perfect

Great plugin! Hasn't been updated for over three years. But it works great, still!

Still works like a dream

Extends the native sticky post functionality to custom post types in a way that is identical to default posts.
