  title: Teads Advertiser Conversion API
  description: >
    Server-to-server Conversion API for advertisers running on the Teads /
    Outbrain combined open-internet platform. Lets advertisers send first-party
    conversion events directly from their backend (or via Google Tag Manager
    server-side container) to Teads for campaign measurement, optimization,
    attribution, and audience signals — independent of browser cookies. Modeled
    on the public Teads Conversion API GTM server-side template and Teads /
    Outbrain advertiser tagging documentation.
