  title: Interpublic Group WordPress REST Root API
  version: root
  summary: The live WordPress REST API served by the Interpublic Group corporate website.
  description: 'Derived verbatim from the route-discovery document the Interpublic Group web server publishes
    at https://interpublic.com/wp-json/ (fetched 2026-08-12, HTTP 200). Every path, method, parameter
    name, type, default and enum in this document was read from that live response; nothing was invented.


    This is the content-management API of the corporate marketing site, not a product API. Interpublic
    Group is an advertising and marketing-services holding company and publishes no developer product
    API at the holding-company level. The surface is included because it is a real, live, self-describing
    HTTP contract on the provider''s own host: the apex https://interpublic.com still serves the WordPress
    origin (346 posts, X-WP-Total observed) while www.interpublic.com 301-redirects to omc.com following
    the Omnicom acquisition.


    Only the WordPress core namespaces are represented (`wp/v2`, `wp-abilities/v1`, `oembed/1.0`, root).
    Third-party plugin namespaces advertised by the same discovery document (yoast/v1, redirection/v1,
    webdev-insight/v1, wordfence/v1, accessibility-suite/v1, aam/v2, wp-offload-media/v1, wpe_sign_on_plugin/v1,
    wpe/cache-plugin/v1, wr/v1, fluent-smtp, ada-plugin/v1, wp-site-health/v1, wp-block-editor/v1) are
    intentionally excluded as vendor plugin internals.'
