We ran into the same issue today. Even though we don’t use facebook very extensively, comments on posts should definitely become tickets. The connection itself seems to work, as new posts made on the page show up as closed tickets, just as @diwaspuri wrote here.
This is on 5.0.x, Docker-compose, Ubuntu 20.04.3 LTS x86_64
I think the issue lies in inadequate Facebook permissions as when I am about to link the page from self hosted Zammad installation, the following is cautioned by FB.
If this is the case, appropriately documenting the necessary permissions and a ‘screencast’ as is required by FB to get approved, might be helpful for us.
Kindly provide the list of necessary permissions and a screencast, if anybody has been able to get it to work.
The following permissions require approval from Facebook for Zammad to fetch Facebook posts & comments properly.
pages_manage_posts
pages_manage_engagement
pages_manage_metadata
pages_read_engagement
pages_read_user_content
Right now, the official documentation for setting up Facebook with Zammad at Facebook — Zammad documentation seems incomplete as it doesn’t provide the users adequate resources / steps to achieve the linkage.
