url - Facebook send dialog: adding a linebreak in the description

Question

This is an URL I have to send an invitation to an app of mine:

https://www.facebook.com/dialog/send?app_id=MY_APP_ID&
name=hola&
link=http://www.aWebSite.com&
picture=http://www.aWebSite.com/im01068442.jpg&description=participar!&
redirect_uri=http://elsuperdt.com

I'm trying to have a linebreak included within the description, but I just haven't found a way to do so. How do I do it?

Answer 1

I had the same issue and eventually gave up. Facebook seems to have gone to great lengths to avoid letting us have any linebreaks in the description.

The one thing you can do is add a &caption=first%20line which gets you one linebreak between the caption and the description. (There's a pretty short limit on how long the caption can be though - something like 80 characters.)

Update: this no longer works for send dialogs. It does still work for feed dialogs
