Yahoo Conversion API
Server-to-server conversion-event API (CAPI) for campaign measurement, attribution and optimization, positioned as the successor to browser-side Dot Pixel tracking. Two specifications are published - a Standard variant using the conversion structures already present in the Yahoo DSP and Dot Pixel, and a Product variant supporting product-level events for the Yahoo In-Flight Outcomes solution. Requires its own direct OAuth 2.0 setup separate from the DSP Traffic API. Third-party integrations exist through LiveRamp, Narrative and Hightouch.
