Web API Transition Leaderboard

Timelines for MLSs Transitioning 100% to RESO Web API and Sunsetting RETS

U.S. MLS Subscribers Committed and Converted to Web APIThe Real Estate Transaction Standard (RETS) is a data transport protocol that was created 20 years ago by a coalition of real estate industry thought leaders and the National Association of REALTORS®. This group eventually created RESO and its Data Dictionary. RESO deprecated RETS and developed its successor, the RESO Web API.

The industry’s utilization of the RESO Web API is accelerating quickly. At least 90% of MLSs in the industry have RESO-certified Web API services.

In recent years, vendors, brokers and agents have increased their usage of MLS Web API data feeds from less than 5% of the industry to over 40%. More than 60% of MLS organizations have committed to a full conversion.

RESO tracks the migration to the improved Web API standard. If your organization is not listed, please contact us to be included. Please consult our free Web API Transition Guide for advice.
