ChatGPT Ads can only optimize for the sales it sees. PromptPixel sends each paid order to OpenAI's Conversions API with the ad click that led to it, server to server. Unlike a browser-only pixel, an optional theme embed keeps the ChatGPT click even when a shopper blocks tracking, and a dashboard shows every order and whether OpenAI accepted it. Needs a ChatGPT Ads account: paste its Pixel ID and API key, no code. No customer personal data is sent.
