If you are using the GetItems endpoint, it is important to ensure that the parameters are supported in the context of your request. The $top parameter is intended to limit the number of items returned, while $skip is used to skip a certain number of items. However, if the API is not recognizing these parameters, it might be due to changes in the API behavior or restrictions on the specific endpoint you are using.

You may want to check if there have been any updates or changes to the API that could affect how these parameters are processed. Additionally, consider switching to using $skiptoken for pagination, as it is recommended for handling large sets of list items.
