    Offerpad publishes no developer authentication documentation, no API key programme and
    no client registration path. Both auth surfaces below were discovered by probing, not
    from developer docs. Neither grants access to any real estate, listing, valuation or
    transaction capability on a self-serve basis.

      WordPress application passwords, advertised in the wp-json discovery document under
      authentication.application-passwords. Credentials are issued interactively at
      https://www.offerpad.com/wp-admin/authorize-application.php and sent as HTTP Basic.
      Required for every write route and for reads in the edit context; anonymous callers
      get the view context only. Issuance requires an Offerpad WordPress account — there is
      no self-serve signup, so this is effectively staff-only.

    description: >-
      The private customer backend at https://helix.offerpad.com serves an RFC 8414
      authorization-server metadata document anonymously. It delegates to an Okta custom
      authorization server. Public clients (the Offerpad Connect SPA and the Offerpad mobile
      apps) use authorization code with S256 PKCE; there is no public client registration,
      so third parties cannot obtain a client_id.
