Explanation

This indicates that the $filter parameter could not be parsed. If you receive this error message, please review your $filter parameter and look at the features listed in the Filtering in REST page.

The AvaTax API permits you to specify complex filters, but the filter must be constructed carefully. Please review your filter and search for a valid filter clause.
