Web API Transition Leaderboard

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

The Real Estate Transaction Standard (RETS) is a data transport protocol that was created more than 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.

Vendors, brokers and agents have increased their usage of MLS Web API data feeds. Where it was once less than 5% of the industry in 2021, MLS feeds converted to Web API now cover 51.9% of U.S. subscribers. MLS feeds committed to Web API conversion cover 70.4% of U.S. subscribers.

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