Problem:
Once you get everything setup and your permissions right, users are still not able to see comments or updates that have been posted to the ticket. Solution:
We all know that Symfony is already in the core of Drupal 8 but how it works and how both systems work? Not that many people understand fully this integration. Me neither but I would like to pubilsh my research notes about how Drupal 8 works now.
Everyone loves the Services module. It allows you to easily create API endpoints for Drupal's core features, permitting you to interact with Drupal from external applications.
