Reply to ticket api

Hi,

I've been building a custom system that allows clients to view and reply to their tickets. Viewing their tickets is no worry and replying to the ticket is no worry either however when I submit a ticket reply through the "External API" it shows as a staff member has submitted a reply, not the client. I've tried adding the $postfields["clientid"] = "1"; attribute which does add the client id to the tblticketreplies row "userid" but again...the system recognizes it as a staff reply rather than a client reply. How can I fix this?


Any help/suggestions would be greatly appreciated.

Thanks
