01
Pixel and Conversions API
OpenAI supports browser Pixel events, server-side Conversions API events, or both. When the same conversion is sent from both sources, use the same event ID so the platform can deduplicate it.
✦ Conversion measurement
Measure ChatGPT Ads before you optimize them
Reliable optimization starts with reliable conversion evidence. Understand Pixel, Conversions API, oppref, event IDs and attribution before you scale spend.

02
Preserve the click reference
OpenAI recommends preserving the oppref click reference through redirects and landing-page navigation and sending it with server-side events when available. Losing this value can reduce the quality of click-to-conversion matching.
03
Measurement quality is an optimization input
Magnify's operating principle is to separate a real performance problem from a measurement problem. If event coverage is incomplete or duplicated, campaign optimization can move spend in the wrong direction.
04
Expect attribution differences
Ads Manager, analytics tools and other advertising platforms can report different totals because of attribution windows, timestamps, consent/storage conditions, deduplication and modeled conversions. Differences should be diagnosed, not automatically treated as errors.
05
Measurement is an optimization dependency
A channel cannot be optimized toward business outcomes if the conversion layer is incomplete. Treat event naming, event IDs, attribution references, deduplication and server/browser agreement as a data-quality system. When the evidence is partial, the optimization conclusion should remain partial too.

Frequently asked questions
Are context hints the same as Google Ads keywords?
No. Context hints are natural-language descriptions that help explain when an offer may be relevant. OpenAI says they inform relevance but are not exact-match targeting rules and do not guarantee delivery in specific conversations.
Can ChatGPT Ads measure conversions?
Yes. OpenAI supports conversion measurement using the OpenAI Pixel, the Conversions API, or both. Magnify treats measurement quality as a prerequisite for optimization rather than assuming every reported conversion signal is complete.
Should I use both Pixel and Conversions API?
OpenAI recommends using both when appropriate and using the same event ID for the same conversion so events can be deduplicated.
What is oppref?
OpenAI documents oppref as a click reference that can be preserved from an ad click and passed with server-side events to improve conversion matching.
