Hi Systemzee,We've created a mod for osTicket (see discussion thread here) which includes the following API functions:API ticket - create (similar to the original function)API ticket - add client messageAPI ticket - add staff replyAPI topic - get list ("all" or a predefined group)API user - get detailsAPI user - modify (includes "create new user" and "modify existing one")You can see details by following link to our website here.Note, osT+ is a modified version of osTicket with extra features added, however independent from development efforts of the osTicket team. It's free to use, no strings attached.Regards,SebastianosT+: centralised hub to easily handle multiple business areas with responsive design (free osTicket mod)
