How to add Facebook App to Fan Page?

How do I start a Facebook fan page app and get an id/api key?

• I have just set up a "Companies + Organizations" fan page.  I am trying to get to the developers app so I can generate a API Key or App ID.  However, when ever I try http://developers.facebook.com/apps or click on any of  the "developers app" links in the facebook tutorials, all I get is my fan page in admin mode.  Can anyone help me understand this?

• Answer:

  If you want to create an app to be on your page First at the  https://developers.facebook.com/apps page, click on 'Create New App' (located on the top right). Put in a name and a namespace for your app. That web hosting option is if you don't have a host (like http://www.ipage.com/ipage/index.html) then press continue, put in the security text that will appear and then press submit. Now your new app window will appear. Above the 'Select how your app integrates with Facebook' space,  click on 'Page Tab'. Fill in the name of the tab app. Put in the Tab Url, like "http://THEDOMAINOFYOURAPP.com", the secure page tab url is the SSL configured URL, the ones that start with HTTPS. If you haven't got one, install a SSL certificate in your server, or ask for advice with your server's support. SSL certificate can be acquired from many different sellers, but i recommend the COMODO 90-Day tryout Certificate: http://www.comodo.com/e-commerce/ssl-certificates/free-ssl-cert.php. The Page Tab Edit Url can be the same as the normal tab url. And the Page Tab width will be what you need, depends, 520px or 810px (i would go for 810, just more space), then just click 'Save'. So it will look something like this: Now, after you've done your app, to add it to your page is simple, access this URL, replacing the ID and URL of your just made app: https://www.facebook.com/dialog/pagetab?app_id=YOURAPPID&next=YOURAPPURL . NOW, for this to work you must have a running server, fully working with that URL for that App (i mean, you'll need to have created the app already...we'll see that later). So, on the picture below, i used my Realise Network App ID and URL to show you how it works. So the img below will be what will appear: On that, you can choose what Facebook Page you want to add the App to. Select one and click 'Add Page Tab'. Then, it might take you to the App URL (the actual app), but go to your Facebook Page where the App was added, you'll see it there, like this: And there it goes! So now, if you want to make an app, the fastest and easiest way to do that is by using the Facebook SDK's. I use the PHP SDK, its nice. I wrote about the use of Facebook's PHP SDK on this Page: http://realisenetwork.com/developers.php Now, an interesting thing that most users like to have on there pages is the ability to check if the user that is visiting 'likes' the Page. There are some pages explaining that as well: - http://stackoverflow.com/questions/9566575/check-if-user-likes-page-via-graph-api - http://stackoverflow.com/questions/4703678/how-to-determine-if-facebook-user-likes-a-certain-page Now that you have an app up and running you can implement the Social Plugins any way you want! https://developers.facebook.com/docs/plugins/
