SharePoint GET /roleassignments REST API returns 403 Forbidden Error

Question

Hi,

We have a requirement to retrieve RoleAssignments for a SharePoint Site using following REST API:

GET <Site_URL>/_api/web/roleassignments?$expand=Member/users,RoleDefinitionBindings

But this API is retuning 403 Forbidden error:

{
    "odata.error": {
        "code": "-2147024891, System.UnauthorizedAccessException",
        "message": {
            "lang": "en-US",
            "value": "Access denied. You do not have permission to perform this action or access this resource."
        }
    }
}

Does a user need administrator access to retrieve RoleAssignments or what access user need in order to fetch these details using REST API?

Any leads will be appreciated.

Note- The user with which we are trying to fetch RoleAssignments using REST API is a non-admin user.

Thanks,

I checked this with full control with user access but not able to retrieve the permission.

I believe you need site collection administrator access to retrieve the role "RoleAssignment".

Hope this answers your question.
