Can advertisers track conversions from ChatGPT Ads?

What is a Conversions API for ChatGPT Ads?

It's a server-side connection that sends conversion events straight from a company's backend systems to ChatGPT Ads, catching purchases and signups that browser-based pixel tracking can miss, per Tealium.

Tealium adds ChatGPT Ads pixel and server-side conversion tracking

Tealium said Oct. 6 it added a client-side Measurement Pixel and a server-side Conversions API (CAPI) connector for ChatGPT Ads, letting enterprises route website and backend conversion events — purchases, signups, checkouts — into OpenAI’s ad measurement system. Tealium CEO Jeff Lunsford said shared event IDs between the two paths prevent double-counting conversions, per Tealium’s announcement. The integration follows OpenAI’s Oct. 5 expansion to 20 measurement and attribution partners for ChatGPT Ads.

Why it matters: Tealium joining OpenAI's measurement-partner roster gives ChatGPT Ads buyers the same pixel-plus-server-side tracking stack they already run for Google and Meta, treating chat ad spend as a budget line that can be measured rather than taken on faith.

The record: OpenAI ChatGPT
