I am creating a customised Facebook share button. The idea is upon clicking on the Facebook share button, it will pick up the meta tags on the page and prefill the share information with a title, description and image that have been curated.
What URL should I be using for the button? There is https://www.facebook.com/dialog/share and https://www.facebook.com/sharer/sharer.php
I heard the latter has been deprecated? And you can append a whole bunch of information to the URL as well?
I can't quite figure that out.
