How to create a FB application to publish your WP posts and pages on FB. (For other purposes, different than mere publishing, I don’t know)
Go to:
https://developers.facebook.com/apps
Click on “create a new application” (I don’t now exact words in English as I have the page in Italian)
A little form will appear where to put a Name for application and mamespace. Advices will appear in real time if you are doing thing wrong, so correct any error as needed:
* Display name
* Namespace
When done save.
In the next step insert your email address:
* Email address
* and in “Website with Facebook Login” add the Url of your site.
Don’t do anything else and save. That’s it. Now you have a new application.
If you use the application for a publishing plugin, go back to the plugin and insert App ID, App Secret and your fanpage ID then do all the setting you want or needed following the instruction of your plugin.
At this moment I’m using succesfully Simple Facebook Connect.
