FACEBOOK ADD APPLICATION TO FACEBOOK PAGE.
How to Add an application to your Facebook page
After you have created your facebook Application, you need to use the following link to add it:
Before using the link, you need to edit the URL.
First you need to change the "YOUR_APP_ID". Fill in your "App ID/API Key". You can find this on: https://developers.facebook.com/apps Second thing you need to change is "YOUR_URL" at the end. "http://apps.facebook.com/yourappurl/" (the link where your app is located).
After you used the correct URL, you will be prompted to select what facebook page you want to install your Application on.
Be mindful on HTTP and HTTPS, since Facebook is moving towards using Secure link - So eventually you will need a server with SSL.
