I am starting to get to know osticket.
osTicket Version v1.12 (a076918) — Up to date
Web Server Software Apache
MySQL Version 10.2.22
PHP Version 7.3.7
I use email piping to create tickets.
According to the doc, setting a help topic: "Ticket can be assigned a specific help topic, which, if applicable, will also add any custom form associated with that Help Topic."
I can successfully set the help topic (manually or automatically). However, never do these tickets automatically get associated with the help topic's custom form. I can "only" assign the forms manually via the "Manage Forms" UI within the view of an individual ticket.
