Hi
Based on the request of IS team we have recently added support for loading
template files from the registry.
I think with this feature we can do the mapping at Event Publisher side,
then IS can send only the core data for the notification. I think building
the whole message at IS is too much customization for emails.
Please set up a meeting so we can discuss the possible ways to implementing
this.
Regards
Suho
