    Hello @Andrew Mercantini

    Thanks for reaching out.

    I'm able to reproduce the error message you are getting in API response. Seems like you are using Application token (application permission type) while listing plans for a group, which is not supported. Refer this documentation.

    Please provide Delegated token (delegated permission type) with these permissions (least to most privileged) to list plans for a group.

    With Application token:

    With valid delegated permissions:

    Hope this helps.

    Hi @Andrew Mercantini , I tested locally and reproduced the same error, and I find when the user you are authenticated to log in belongs to the group you requested, you will be able to have permissions.
    Hope this helps. Best Wishes.
