GA4 custom dimensions

Mary3 — Tue, 22 Jul 2025 08:43:29 GMT

Hi,

We are trying to use the 'Google_Analytics_4' connection to bring through data. Within GA4 we have a custom dimension that we use that we want to bring through into Qlik (along with other standard dimensions and metrics which do run and come through). The field exists and works in GA4’s Data API (customEvent:analytics_id) however when I have tried to bring it through via Qlik I get

The following error occurred:

Failed on attempt 1 to POST. (The remote server returned an error: (400) Bad Request.).

Is it possible to bring through custom dimensions with this connections and if so how (I have tried different variations on the name, in quotations, in brackets etc but none seem to work).

we are on this version

Thank you for any help
