I am trying to customize a user's message when he/she shares a link on our site via FB similar to this one:

enter image description here

I have read Facebook share button and custom text but it only changes the small texts below and not the main "status". Any links on how to go about this?

Thanks!

It is not possible to change/prefill the message text in the FB.ui dialogs, and it is not allowed according to the platform policy. The message must be 100% user generated and prefilling is not allowed:

https://developers.facebook.com/policy/

2.3: Ensure that all content in the user message parameter is entered by the user. Don’t pre-fill. This includes posts, messages, comments, and captions.

The only possibility to fill the message parameter is to use an API call to /me/feed with the publish_actions permission - but still, you are not allowed to prefill and publish_actions has to go through a review process. Facebook will never approve it if you prefill, of course.
