I need to make SOAP requests from OTRS 3.3 to a WCF service I'm currently implementing when a ticket in OTRS is created, changed or deleted. I need it for sending emails containing information about the changed ticket. Therefore, it would be nice that this SOAP request contained full information about the ticket.
All I can find after googling is that OTRS has invokers mechanism that can be configured to call SOAP services when a desirable event is fired including ticket creation, changing or deleting.
But when I go to the Admin -> Web Services -> My service, there is no invokers in the Add Invoker dropdown under the OTRS as requestor section.
What should I do next in order to attach an invoker that makes SOAP request with information about changed ticket? Or latest OTRS version doesn't contain invokers out of the box and I have to implement it by myself using Perl programming language?
