Good Morning,
I have the same problem as the user ANTHONYBANDARAS.
I need to get the Offense ID parameter to be able to add it to the email notification template. This case does not help me because the custom property you indicate is for when a user has been assigned a crime and what I need is that when an event is generated, the Offense ID parameter included in that mail.
I do not know if there is any way to add the Offense ID parameter to the email notification template of the events.
From what I have seen in: https://www.ibm.com/support/knowledgecenter/SSKMKU/com.ibm.qradar.doc_cloud/t_CONFIGURING_CUSTOM_EMAIL_NOTIFICATIONS.html
you can only add certain parameters in that template and you would need to include the Offense ID parameter in some way.
When I put in the template of mail notification this line $ {OffenseID} when putting the command /opt/qradar/bin/runCustAlertValidator.sh I get the following error:
Invalid field: OffenseID
Regards, and thank you very much.
