OpenAI Ads Insights: new Platform breakdown, conversions re-read for 32 days

OpenAI Ads added a platform breakdown to its Insights API: each row can be split by the ChatGPT app or web browser the ad was shown in. Improvado now ingests it as the new Platform field of the Insights report. The report also re-reads more days, so conversions that OpenAI credits late reach your data.

The Platform field

Selecting Platform returns one row per platform per entity per day, at every aggregation level: Ad Account, Campaign, Ad Group and Ad. The values are:

• ios_app, android_app, macos_app, windows_app - the ChatGPT app on that operating system. OpenAI started reporting the desktop apps separately in late October 2026; earlier desktop app delivery is under unknown.
• desktop_web, ios_web, android_web - ChatGPT in a web browser, split by operating system from 10 September 2026.
• web - web delivery without that split: all web delivery before 10 September 2026, and web clients OpenAI cannot classify after it.
• unknown - delivery without recognized client information.

Platform rows add up to the report without the breakdown: impressions and clicks per entity and day match exactly, and spend matches to within a cent or two of rounding.

Rules the API enforces

• Data starts on 3 August 2026. OpenAI returns no platform rows for earlier days, even where the account had delivery, so a Platform extraction loaded further back shows no rows for that period.
• One breakdown at a time. Platform cannot be combined with Country, Device Type or the product fields in the same extraction. Device Type stays a separate breakdown (desktop or mobile).
• No conversions per platform. OpenAI Ads does not report conversions by platform. Selecting Platform together with Conversions is refused when you save the extraction, so keep Conversions in a separate extraction without the breakdown.

Conversions are re-read for 32 days

Since 30 September 2026 the Insights Conversions figure counts click-through and view-through conversions together and dates each one by the day of the click or view, so a day keeps gaining conversions for up to 30 days. Insights extractions on the default refresh window now re-read the last 32 days on every run instead of 14, the same as the Conversions Insights report, so late conversions and OpenAI's corrections reach your data without a manual reload.

Insights keeps OpenAI's default attribution: 30 days after a click and 1 day after a view. For click-through and view-through conversions as separate columns, or for shorter windows, use the Conversions Insights report.
