  version: 0.1.0
  summary: Per-tenant, website-facing search and enquiry API powering Apex27-built estate agency websites.
  description: 'API Evangelist DERIVED description of the Apex27 Portal API.


    Apex27 publishes no OpenAPI, Swagger or reference documentation for this surface. This document was derived mechanically from Apex27''s OWN published n8n community node — npm n8n-nodes-apex27portal@0.1.0, publisher "james_apex27" — which contains the complete operation set, query and form parameters, enumerations and the auth mechanism.


    It is NOT a provider-published contract. The Portal API has no shared host: the base URL is each agency''s own Apex27 portal domain with `/api` appended. The server URL below uses the vendor''s OWN published placeholder host verbatim; substitute the agency domain. Authentication is an `api_key` query-string parameter issued under Admin Panel > Websites > [Your Website] > Integrations tab > Portal API section.'

      note: Apex27PortalApi.credentials.js declares the api_key query parameter and the https://portal-abcd1234.apex27.co.uk/api base-URL placeholder used as the server below.
    caveat: Per-tenant API. There is no shared production host to probe, so no live status codes were recorded for this surface.
