Hi @edkmak,
Have you uploaded the rule to the cloud.? If yes, do a GET call https://{{tenant}}.api.{{domain}}.com/cc/api/rule/list and you should be able to get the rule ID and name, which can then be added to your Azure source.
If the rule is not deployed yet, you can raise a SailPoint ticket to do that or make use of the SP-config. Take a look at the below thread which can be helpful.
