(I created a REST WEB SERVICE from OTRS interface with TicketCreate operation)
1. ticket was created
2, notification was created, but some tags like <OTRS_CUSTOMER_BODY>, or <OTRS_NOTIFICATION_RECIPIENT_UserFirstname> and maybe others are not replaceable, in notification, so I want that body from the ticket created to be visible in body of notification, but appear jus "No body" and other tags missing.
If somebody can help with this, we'll be good, Thanks all !
