I first send this API code to create the Comment using a POST, then store the returned Content ID, 	Comment api_Body: {"Content":{"LevelId" : 284,"FieldContents" :{"18700":{"Type": 1,"Value": "PyDAT Monitoring Created Date","FieldId": 18700},"18701":{"Type": 1,"Value": "12/16/2022 07:41:27","FieldId": 18
701}}}, "SubformFieldId": 18681}
Then I use that Content ID in the below to update the Finding with a PUT, Finding api_Body: {"Content":{"Id" : 392384,"LevelId" : 62,"FieldContents" :{"2670":{"Type": 1,"Value": "PII Monitoring - Prod PII Detected for BIIPOD in Non-Prod Environment BIPODSD2","FieldId": 2670},"2265":{"Ty
pe": 1,"Value": "Monitoring is showing that Non-Production data instance XXXXXX contains Prod PII data. Please refer to PowerBI Report URL removed","FieldId": 2265},"19913":{"Type": 4,"Value": {"ValuesListIds" : ["73229"], "OtherText" : null},"FieldId": 19913},"19294":{"Type": 4,"V
alue": {"ValuesListIds" : ["76051"], "OtherText" : null},"FieldId": 19294},"19126":{"Type": 4,"Value": {"ValuesListIds" : ["71561"], "OtherText" : null},"FieldId": 19126},"19125":{"Type": 4,"Value": {"Value
sListIds" : ["71556"], "OtherText" : null},"FieldId": 19125},"11132":{"Type": 9,"Value": [{"ContentId":317931}],"FieldId": 11132},"2671":{"Type": 8,"Value": {"UserList" :[{"Id": 18620}],"GroupList": null},"
FieldId": 2671},"18681":{"Type": 24,"Value": [393200],"FieldId": 18681}}}}
The last FieldID 18681 is the ID for the Comments field in Findings.
