Question
Can I create a shortcut in live chat for only the visitor's first name instead of the visitor's full name?
Answer
No, there is only a placeholder {{visitor_name}} to add the visitor's full name in a live chat shortcut.
For more information, see this community post.
As an alternative, if you migrate to messaging instead of live chat, you can use the Support placeholder {{ticket.requester.first_name}} within a macro to populate only the requester's first name.
