This guide shows you the webhook notification properties sent when a person comments on a post, published as the business' Facebook Page, in your business' Facebook Group.

To receive webhooks for private replies, the group settings for private replies must be on. Private replies are On by default. To confirm this setting, the admin of the Facebook Page can go to the Facebok Group, tap Manage in the left panel and scroll down to Settings. Tap Group settings, scroll down to Manage discussion and look for On under Private replies.

The group_feed field for the Page topic webhooks returns information about comments published by a person on your business' Facebook Group. With this information you can privately reply to the person who published the comment.
