This can be quite challenging because GA4 has changed quite a lot from UA, including how the data is structured and reported. For GA4, there is currently no public reporting API like there was for UA. As of now, GA4 only has the Data API which is in alpha phase and does not provide the complete functionality of the previous version. This might be the reason why your events and parameters are not returning the expected data. Also, custom dimensions and metrics are treated as event parameters in GA4, so there may be changes in how they are queried. For accurate implementation, it would be best to check Google’s up-to-date documentation or reach out to Google’s support network for guidance.
