The REALTOR.ca Data Distribution Facility (DDF®) Web API is CREA's national listing distribution surface, exposed as OData v4-style read endpoints over Property, Member, Office, OpenHouse and Destination resources, with per-resource Replication endpoints for full and incremental (LastUpdated) pulls. MLS® System data received from Canadian boards and associations is normalized to the RESO Data Dictionary. All endpoints, including the OData $metadata document, require an OAuth 2.0 Bearer access token obtained with data-feed credentials; anonymous requests return HTTP 401.
