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 and operates combined brand operations under omc.com. IPG does not publish a unified public developer portal or open REST APIs; technology surfaces are delivered through agency-network products such as Acxiom data services and Mediabrands' identity and measurement platforms.

No public REST APIs are published by Interpublic Group at the holding-company level. Developer-facing surfaces exist inside individual networks (Acxiom, IPG Mediabrands) and are typically partner-gated. This repository will be extended if and when IPG or its successor entity publishes openly accessible APIs.
