Chat Departments are used to control access to Chats in conjunction with User and Agent permission groups, you can manage these through Channels > Chat > Departments.

Chat Departments are a separate system from Ticket Departments - creating a Ticket Department will not create the corresponding Chat Department.

Chat Departments & Agents

Chat Department permissions control which Chats Agents can accept.

Manage permissions for each Department by going to Channel > Chat > Departments, choosing a specific Department and selecting the Permissions tab.

Unlike the two permission levels of assign/full access for Ticket Departments, Chat Department access is either on or off.

Chat Departments Users

Like all  Usergroup Permissions, User Chat Department Permissions are set through Usergroups.

Usergroups control which Departments Users can select when they initiate a Chat.
