What is IDX Web API and RETS?

The Real Estate Transaction Standard (RETS) was mandated for use on all MLS Boards by mid 2009 by the National Association of REALTORS® in an effort to standardize programming language used by MLS systems nationwide.

These days The Real Estate Standards Organization (RESO) and Web API now provide a coherent, consistent and simpler method of managing and accessing data.

The concept of having all MLS (multiple listing services) real estate systems using the same language is a valid way of standardizing computer languages and eliminating the need of learning multiple languages by software vendors such as ourselves.

RESO is evolving steadily and is the new method of IDX data sharing by local MLS Boards. For developers of IDX websites, RESO and Web API allows faster deployment into new markets. This encourages more third party vendors such as the UltimateIDX™ to enter new markets resulting in better service and productivity for MLS customers.

Another advantage of RESO and Web API is the frequency of data updates available to REALTORS® on their personal real estate websites. Some local boards allow updates frequently throughout the day giving potential buyers the most accurate information available. These frequent MLS data updates are extremely beneficial to Brokers, Agents and potential buyers that visit these real estate sites.

UltimateIDX Use Of Web API

The UltimateIDX encourages and supports the use, development and implementation of RESO standards and Web API with all MLS systems nationwide. In addition to offering our MLS Clients the latest Web API services available, our entire system is built using RESO standards. This ensures our Clients receive the benefits of RESO such as constant updates throughout the day and support for sold properties (where available) too.
