Using a case number I can use the SIEM API (caseGetCaseDetail) to retrieve the esmID.
Once I have the esmID I use it as input for ipsGetAlertData which returns the alert data.
I was wondering If it is possible to do a reverse search based on the alert data? Below is a snippet of the data retutned. Would it be possible or is there a call that I could make to retreive the alert data if I used External_EventID=12071295131225806731 ?
