The RESO Transport workgroup is proud to announce an update to RETS Web API (now version 1.0.2).

The goal of this standard is to provide a more open data approach using the widely-adopted RESTful (REpresentational State Transfer) technology in use by many industries today.  RESO’s move toward a RESTful standard is to encourage and promote access to real estate information directly from web, mobile, social and other HTTP-based applications.

The 1.0.2 standard leverages the best of Global Technologies and is built upon, in part, the OData v4.0 standard.  Extensive efforts put forth by the RESO Workgroup volunteers has ensured the future of the transactional specification to conform to OData 4.0 in order to provide off the shelf OData tool set compatibility for the Real Estate Industry.  The new specification provides a number of updates based on feedback from the workgroup and RESO membership.  Content was added to or modified in nearly all sections to help clarify content or answer open questions.  The Data Dictionary v1.3, v1.4, and the EDMX are currently being generated for the API Specification and should be completed no later than end of September.  The 1.0.2 Specification is the officially approved and ratified standard by the RESO Board of Directors.  Realtor owned and/or affiliated MLSs will have till June 30, 2016 to implement and certify against the RESO Standards through the RESO Compliance Certification Process per the N.A.R. Mandate in the MLS Policy Statement 7.90.
