Has the User Requests ATOM Feed API Payload Recently Changed?

Summary:

We are currently utilizing the User Requests ATOM feed API (/hcmCoreApi/atomservlet/user/userRequests) to retrieve all newly created user records for our downstream integrations.

Previously, we relied on the userCategory field to distinguish non-worker user records, such as supplier records or service accounts. However, earlier this year, we observed that this field is no longer present in the API payload response. This change led to failures in our integrations and required us to modify our code accordingly.

Could someone please confirm whether there have been any updates or changes to the API that might explain the removal of this field?
