I have no idea what it is that you are trying to ask... also 1.9.8 is end of life / out of support and has been for a very long time.

API documentation is at:
https://docs.osticket.com/en/latest/Developer%20Documentation/API%20Docs.html?highlight=api
and
https://docs.osticket.com/en/latest/Developer%20Documentation/API/Tickets.html

And I wrote this document a long while back which also might point you in the right directoion.
