Conversion API (CAPI)

A server-side method of sending conversion events to platforms, more durable than browser pixels.

Also known as: CAPI · Conversions API · Server-side tracking

A conversion API (CAPI) sends conversion events to ad platforms from a brand's server rather than the browser, making measurement more resilient to ad blockers and cookie deprecation.

It complements the browser pixel and aligns with the first-party, server-side direction creator-commerce attribution already takes.
