# Interpublic Group

**APIs profiled:** 4

The Interpublic Group of Companies (IPG) is one of the world's largest advertising and marketing services holding companies, with networks including McCann Worldgroup, IPG Mediabrands, FCB, MullenLowe Group, and Acxiom. In 2024 Omnicom announced its acquisition of IPG; the combined brand operations now run under omc.com, and www.interpublic.com 301-redirects there. IPG publishes no unified public developer portal and no product REST API at the holding-company level - technology surfaces are delivered through agency-network products such as Acxiom data services and Mediabrands' identity and measurement platforms, all partner-gated. The one live, machine-readable HTTP contract on IPG's own host is the WordPress REST API still served from the apex interpublic.com origin, which carries the corporate newsroom (346 posts) and advertises 254 routes across 17 namespaces through its self-describing route-discovery document.
