ChatGPT Ads added Shopify and HubSpot integrations alongside conversion optimization updates

In the same announcement as Sponsored Agents, OpenAI rolled out new ChatGPT Ads integrations with Shopify and HubSpot and further conversion-optimization and attribution controls, making it easier to pass ecommerce and CRM conversion data back into the Ads Manager.

• New third-party integrations: Shopify and HubSpot, joining earlier partners such as WorkMagic.
• OpenAI also cited conversion optimization, flexible attribution windows and granular platform targeting in the same rollout; platform targeting and view-through windows shipped in late August 2026.
• Together with the Ads Manager plugin released on September 4, 2026, this rounds out the measurement stack for self-serve ChatGPT advertisers.
