      RESO Platinum-certified Web API providing OData 4.0-compliant access to MLS listing data normalized to the RESO
      Data Dictionary. Resources include Property, Member, Office, OpenHouse, Media, Room, UnitType, and other
      RESO-defined entities. Supports $filter, $select, $expand, $orderby, $top (page size), and $count OData query
      options, plus Bridge extensions like the unselect parameter and the maxpagesize header (default 10, max 200). Data
      is refreshed every 10 minutes or less per MLS feed. Bridge is preparing datasets for RESO Data Dictionary 2.0
      certification.

      Bridge's native (non-OData) RESTful Web API serving the same normalized MLS resources (Properties, Members,
      Offices, OpenHouses, Rooms, UnitTypes, and off-market data where licensed) as flat JSON. Provides a simpler
      request/response shape than the OData endpoint while preserving RESO Data Dictionary field naming. Media is
      returned as an object on the Property record and is hosted on a CDN. Requires a server token or access token
      issued by Bridge per dataset.

    description: >-
      Manage webhook endpoints that receive real-time POST events from Bridge for listing create/update/delete and other
      dataset changes, eliminating the need to poll the Web API. Endpoints require an HTTPS URL with a valid X.509
      certificate; Bridge issues a PKI public key (PEM) for payload signature verification. Events are delivered as
      application/json; endpoints must respond 200 quickly. Failed deliveries are retried with exponential backoff for
      up to two days. Webhooks begin in a disabled state for testing before activation.

  Bridge (Bridge Interactive / Bridge Data Output) is a Zillow Group company that runs the Bridge Platform — a RESO
  Platinum-certified MLS data distribution service used by Multiple Listing Services and brokerages across the US and
  Canada. The Bridge RESO Web API exposes normalized listing data (Property, Member, Office, OpenHouse, Media, Room,
  UnitType) via OData 4.0 at api.bridgedataoutput.com/api/v2/OData, with a parallel native Bridge Web API serving the
  same resources as flat JSON. A Webhooks API delivers real-time listing change events with PKI-signed payloads. Bridge
  also distributes Zillow Group Data — parcels, assessments, and ZHVI/ZORI economic feeds — through the same API
  surface.
