My Open Graph is still not configured and in my Facebook Application Page it does not appear the Open Graph menu item.
I would like to know if it's possible to create an action for login. I mean: every time a user logs in my website, it creates a post in timeline "XYZ is visiting WebSite ABC".
In this case, which Open Graph plugins are necessary? Currently, all of them are not available in my Joomla, as you can see in the picture below.
I need to install all of them, or only a group of plugins required for this?
Right now, we don't have an action for logging in or registering. We're looking into the possibility of adding such an action, but we need to verify with Facebook that that's a legitimate type of thing to post into a user's Timeline. There are some things that they don't want being posted on behalf of a user because it's not 'important' actions.
We do like the idea though, and would love to have a plugin for that in the future.
You have to click the "Edit Settings" link to see the Open Graph options in your app.
For reading an article, you should use either the Open Graph - Content or Open Graph - K2 plugins. You can see the full Open Graph Actions for Joomla configuration guide.
Hope that helps,
