Share Dialog

The Share dialog gives people the ability to publish an individual story to their timeline, a friend's timeline, a group, or in a private message on Messenger. The Share dialog does not require Facebook Login or any extended permissions, so it is the easiest way to enable sharing on the web.

This documentation describes how to implement the Share dialog on the Web. To implement the Share dialog in a mobile app, see Sharing on iOS and Sharing on Android.

The following is an example of the Share dialog that is sharing a link to a user's timeline.

In the preceding image Share on your own Timeline is selected in the drop-down list for choosing the audience for the share. The drop-down list for choosing the audience for a share doesn't appear when a person is on a browser that is not logged in with a cookie. This is also true if the app uses the feed dialog instead of the share dialog or if the app uses iframe web view.

If you are the Webmaster for a page that is shared to Facebook, include open graph meta tags to customize the story that is shared back to Facebook. It's important that you mark up your website with Open Graph tags to take control over how your content appears on Facebook. For more information, see A Guide to Sharing for Webmasters.
