I am connecting to the Facebook API using HybridAuth on the server side (backend is written in PHP). This is for a SaaS publishing application that is hosted on our servers. I understand the mechanics of OAuth and that once I accquire the appropriate permissions from the user, I can write and read from the Open Graph API, which in theory will allow me to do almost anything.
The problem is that I would like to use some of Facebook's social plugins. In particular, I would like to implement the like button so that it automatically appears for each blog post, article and page.
The problem is that the like button and the various Facebook plugins require an app_id. I would prefer not requiring users to add the developer app to their account and creating an app to get an app_id as it can be a confusing process for non-developers.
Is there anyway we can create or retrieve an app_id from open graph (which we can store and use to generate the like buttons and other facebook widgets)?
With the migrations, I understand that each liked URL will not have it's own page. Once the user clicks a like button on your site, he automatically likes your page. However, let's say I have a page called http://www.mystore.com/products/some-awesome-product and there are other similiar pages, all with a like button. Is it possible that when clicking like, the user automatically likes our Facebook page, but when an item is published in their news feed for the like, the URL links to that specific product? Effectively, is there a way for users to like multiple pages from my site?
Update: It looks like we can generate app_ids programmatically with the create application API in the legacy REST API. However, this does not seem to be an option with the graph API.
