I am using Koala to post on my Facebook wall and I would like to mention a page. But the following doesn't work:
@graph.put_wall_post("This page rocks: @[1466840030227949]")
Any way to do this with Koala? And without Koala?
I know this is old, but this answer may help someone else who ends up here.
the syntax above is correct with Koala. To mention a Facebook Page you need to include @[page-id] in the message parameter.
To use Page Mentioning with any Facebook Page, your app need to have been granted the manage_pages and publish_actions permissions. Your app will also need approval for the Page Mention feature.
There is a way to test this without being approved for the permission or feature but please check out my related question and the Facebook docs for more information on how to do that.
