    HOW DATAHASH SETS IT UP

    From kickoff to verified events.

    1. Connect

      Columns from your GA4 events align to OpenAI's Conversions API in the visual mapper, hashed as each event fires and checked for OpenAI's web measurement rollout.

    3. Deliver

    FAQ

    Asked on almost every call.

    How often does the GA4 OpenAI Web CAPI sync run?

    The pace follows your GA4 events: Signals sends changes from GA4 to OpenAI as each event fires. Because it forwards each event as it arrives, a web-conversion feed mapped and ready before OpenAI's surface launches stays current while analytics teams instrumenting GA4 keep OpenAI's web measurement rollout in view. Delivery needs no export and no manual upload.

    What match rate should a GA4-sourced OpenAI Web CAPI batch expect?

    In GA4, match rate tracks the email and phone quality your GA4 events carry. Clean identifiers land for OpenAI; blank ones never will. The first Conversions API report shows analytics teams instrumenting GA4 where OpenAI's web measurement rollout needs work, a data-quality task handled in GA4.
