Currently we do not have any API to allow autopost to social media, but I will explain how it work when you click social button from backend blog listing page, you can check my attached screenshot below which place i mentioned.

When you click share button from the dialog, it will go to this blogs controller php file.
JoomlaRootFolder/administrator/components/com_easyblog/controllers/blogs.php (function autopost())
When it call following autopost function, it will go to post library.

			$post = EB::post($id);

			$post->autopost($oauth->type, true);

This is post library php file -> JoomlaRootFolder/administrator/components/com_easyblog/includes/post/post.php then it will call this function autopost()

Then you will see it will call this following method to proceed autopost :

EB::autoposting()->shareSystem($this, $type, $force);

The file is located at JoomlaRootFolder/administrator/components/com_easyblog/includes/autoposting/autoposting.php (function shareSystem())

After that it will call this push method.

		$table = EB::table('OAuth');

		$table->load(array('type' => $type, 'system' => 1));



		// Push the item now

		$table->push($post);

This method is located at this file JoomlaRootFolder/administrator/components/com_easyblog/tables/oauth.php (function push())

This is the part get all the post data and send to Facebook.

		// Now we do the real thing. Get the library and push

		$lib = EB::oauth()->getClient($this->type, $key, $secret, $callback);

		$lib->setAccess($this->access_token);



		// Try to share the post now

		$state = $lib->share($post, $this);

That share method is located at this file -> JoomlaRootFolder/administrator/components/com_easyblog/includes/oauth/adapters/facebook/client.php

And the Facebook API is located at this file -> JoomlaFolder/administrator/components/com_easyblog/includes/oauth/adapters/facebook/base_facebook.php

Hope this will help.

Ok, will get my hands dirty with this, and let you know, if its good,
The references you showned, I think I need just this (Just confirming is it ost or post?)

$post = EB::oost($id);

$post->autopost($oauth->type, true);

I guess : p together went to smily

yes, that is true, it should contain the p.

[gist type="php"]
$post = EB:post($id);
$post->autopost($oauth->type, true);
