Facebook auto publish Without https?

At present we need to submit the Facebook app for review to get it approved(for permissions publish_pages and manage_pages). You can use the approved app in the plugin if your site is https.

Or our alternate solution where you can use an already approved app for publishing your wordpress posts to Facebook(will work for both http and https sites).
For this select Application Selection as Use smapsolution.com’s Facebook application in WP Facebook Auto Publish’s settings page.
Please note that “This solution is a paid service and the price starts from USD 10 per year”.
