    Hi Dennis

    Thanks for this guide, much appreciated.

    I’m just checking the best way to retrieve the Sensativity Label ID?

    Hi Simon,

    Do you want to retrieve it manually or do you mean from within a Power Automate cloud flow?

    For the manual scenario you can go to Purview click on the sensitivity label to see the details you want to use and find the id in your Network tab of the Developer toolbar. There should GET request with an URL like:
    https://compliance.microsoft.com/apiproxy/di/find/Label?tenantId=yourtenantid&filter=Identity eq ‘5e06f0a7-9d7b-4dfe-bc22-bb1a43a1ff46’

    Dennis, this is a great post. I am attempting this action and for some reason getting the following error.

    {“lang”:”en-US”,”value”:”Attempted to perform an unauthorized operation.”}

    If I pass the same patch with the same label as currently assigned to the site, it completes successfully. Thus I cannot change the label from one to another. Any ideas?

    I am using an azure app registration and the HTTP action in power automate and I am positive the permissions are correct.
