While GA4 processes data, it can sometimes take a few minutes for events to appear in the Google Analytic 4 realtime interface. If you don’t see your event after a couple of minutes, we recommend first checking that you receive a positive response from Bidding signals when dry_run is set to true.
If you’re receiving an 'OK' response for requests with dry_run set to true, but your events still aren’t showing up in the Google Analytics 4 realtime interface, please reach out to Alvie support team for further technical assistance.
