This GET endpoint is used to get tax information for a specific user identified by their user_token. It provides access to historical tax attribute values as well as the ability to perform attribute velocity checks. To use this endpoint, replace user_token in the URL path with the actual user token of the user whose tax information you want to retrieve. This endpoint's purpose is to aid in the identification of users with matching attribute values and to prevent fraudulent activities by monitoring unusual attribute value changes over time. It compares the provided attribute value to the historical attribute values for the same user to see if it meets the velocity check criteria.
