Property Web Service Response Field Updates

Written by Melissa Team | Jan 22, 2026 8:00:00 AM

As part of our ongoing effort to improve the coverage of our property and deed data, we recently completed a detailed reevaluation of the source data that powers the Property Web Service.

While the overall scope and functionality of the service remain unchanged, this work has led us to reintroduce a number of fields that were previously deprecated.

Why These Additions Matter
