In Facebook, everything has an ID. So if you want to get any account or page ID which will never change by years. You can do it by visiting http://graph.facebook.com/-------- after the (/), just paste the username for the page or account. So, if we want to get the ID of Obama's Facebook official page, this is the way: 1. Go to http://graph.facebook.com/barackobama 2. The ID: 6815841748 That's it
Can I use that as the app_id or do I have to go through the process for creating apps for each subdomain on my site? <metaproperty="fb:app_id"content="1234567890"/> Code (markup): https://developers.facebook.com/docs/opengraph/using-objects
If you are adding facebook's open graph meta tags to your pages one of the options they have is the app_id I'm just wondering if we can use the id you mention of if I have to add a app in facebook's developer area.
There is a difference between pages ID and apps ID, it's hard now to create new app. Anyway you can buy it and you need App ID and App Secret.
An App ID and a Page ID are two different things. If you require an App ID, for the Facebook Comments plugin for example, you can create one App ID that will work anywhere on your website. Shoot me a note if you want help doing this. A Page or User ID has a variety of uses. For instance, if you wanted to integrate Facebook Comments, you would need both an App ID and a User ID. The User ID would be used to identify the moderator(s) for your Facebook Comments. I hope that helps.
