Why It Matters
RESO compliance isn't optional
📋
NAR Mandate
All NAR-affiliated MLSs must adopt RESO Data Dictionary 2.0 within one year of ratification. Non-compliant associations face public listing on RESO's non-compliance board.
⚡
Vendor Integration Speed
Before RESO standards, a single MLS feed integration took 25+ hours. With Web API, it takes 2–16 hours. Bad data costs your vendors time and your members money.
🔒
Data Security
Proper OAuth 2.0 implementation protects member PII. A misconfigured endpoint exposes your MLS to unauthorized access and potential liability.
📈
Member Value
Clean, standardized data means better IDX websites, better CRMs, and better tools for your REALTOR® members. Data quality is your MLS's core asset.
